Submissions
Authors are requested to submit their original manuscript and figures online via http://ees.elsevier.com/mep/. This is the Elsevier web-based submission and review system. You will find full instructions located on this site - a Guide for Authors and a Guide for Online Submission. Please follow these guidelines to prepare and upload your article. Text files should be provided in Word format if possible; if you cannot upload such files, please provide a word count of your article. Once the uploading is done, our system automatically generates an electronic pdf of the paper, which is then used for reviewing. When submitting your paper in any format (including LaTex), please ensure that the equations have translated correctly in the pdf built by the online submission system. All correspondence, including notification of the Editor's decision and requests for revisions, will be managed via this system.

On first submitting an article, authors must suggest the names of five potential referees. The suggestions should include names e-mail addresses and details of their affiliations. Authors should only include suggested reviewers with whom they have no previous working relationship. All suggested reviewers should also be from a different country to the corresponding author. It is at the discretion of the Editors as to whether any of these referees are used to review the manuscript.

Authorship
All authors should have made substantial contributions to all of the following: (1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting the article or revising it critically for important intellectual content, (3) final approval of the version to be submitted.

Changes to Authorship
This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts:
Before the accepted manuscript is published in an online issue: Requests to add or remove an author, or to rearrange the author names, must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include: (a) the reason the name should be added or removed, or the author names rearranged and (b) written confirmation (e-mail, fax, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship has been agreed.
After the accepted manuscript is published in an online issue: Any requests to add, delete, or rearrange author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.

Acknowledgement of other contributors
All contributors who do not meet the criteria for authorship as defined above should be listed in an acknowledgements section. Examples of those who might be acknowledged include a person who provided purely technical help, writing assistance, or a department chair who provided only general support. Authors should disclose whether they had any writing assistance and identify the entity that paid for this assistance.

Author declaration form
All authors must complete and submit with their manuscript an author declaration form. The declaration statements should also be included in the manuscript prior to the references. Within the form, authors must declare:

Conflict of interest
All authors must disclose any financial and personal relationships with other people or organisations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding.

Role of the funding source
All sources of funding should be declared. Authors should declare the role of study sponsors, if any, in the study design, in the collection, analysis and interpretation of data; in the writing of the manuscript; and in the decision to submit the manuscript for publication. If the study sponsors had no such involvement, the authors should so state.

Structure of manuscript
If you would like advice on how to structure your manuscript, then you may wish to consult the following reference:Brand RA and Huiskes R. Structural outline of an archival paper for the Journal of Biomechanics. J Biomech 2001;34:1371-4This paper is available free via the Journal of Biomechanics' website (http://www.jbiomech.com/article/S0021-9290(01)00104-X/fulltext). Although it was written for that journal, its general comments are equally applicable to Medical Engineering & Physics.

Abstract
Papers should be provided with a summary of between 100-200 words, explaining why and how the work was done, and what were the results. Abstracts are often featured in secondary source publications and will attract readers if they are succinct, quantitative and avoid unnecessary jargon. The incorporation of appropriate keywords will help ensure that the paper is referenced properly in scientific databases. Authors should, if possible, indicate under which of the Journal's main subject areas their manuscript falls.

Illustrations
Information relating to the preferred formats for artwork may be found at http://ees.elsevier.com/mep/.

Almost all illustrations will be reduced in size to fit a single or double column width. The authors should ensure that lettering and numerals on the figures will remain legible after reduction. Figure captions should be typed in double spacing on a separate sheet and numbered consecutively.

Colour illustrations will be considered if pertinent to the scientific understanding; prices are available on application. Please make sure that artwork files are in an acceptable format (TIFF, EPS or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable colour figures then Elsevier will ensure, at no additional charge, that these figures will appear in colour on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in colour in the printed version. For colour reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for colour in print or on the Web only. For further information on the preparation of electronic artwork, please see http://www.elsevier.com/wps/find/authors.authors/authorartworkinstructions.Please note: Because of technical complications which can arise by converting colour figures to "grey scale" (for the printed version should you not opt for colour in print) please submit in addition usable black and white versions of all the colour illustrations.

Tables
Tables should be accompanied by a suitable caption at the top. Column headings should be brief, and indicate units of measurement in parenthesis.

References
These should be indicated in the text by superior numerals that run consecutively throughout the paper. The references should be grouped in a section at the end of the text in numerical order and take the form; author's surname and initials, title, journal title, year of publication, volume number, page numbers. If in doubt authors should always write the journal title in full. References to a book should take the form: author's surname, followed by initials; title of book in single quotes; editors (if any); volume number/edition (if any); name of publisher, place of publication; year of publication and page number(s). Where a paper is cited more than once in the text, the same superior number should be used on each occasion. References to `submitted' works should not be made and references to conference proceedings should be avoided. Where references are cited `in press', a copy of the relevant manuscript should accompany the submission to help the reviewing process. `Personal communications' are not acceptable as references.

Mathematical formulae
All symbols used in mathematical formulae should be defined in the text. The proof of a formula should be provided in an appendix or reference made to where the proof is shown. It is the authors' responsibility to ensure that equations and figures have transferred and built correctly in the PDF prior to submission.

Page numbering
Authors are requested to include page numbering and continuous line numbering throughout.

Units and abbreviations
SI units should be used. On graphs, if values are recorded in non-SI units then additional scales in SI units should be used. If a large number of symbols are used it is helpful if authors submit a list of these symbols and their meanings.

Randomised controlled trials
All randomised controlled trials submitted for publication in Medical Engineering & Physics should include a completed Consolidated Standards of Reporting Trials (CONSORT) flow chart. Please refer to the CONSORT statement website at http://www.consort-statement.org for more information. The Journal has adopted the proposal from the International Committee of Medical Journal Editors (ICMJE) which require, as a condition of consideration for publication of clinical trials, registration in a public trials registry. Trials must register at or before the onset of patient enrolment. The clinical trial registration number should be included at the end of the abstract of the article. For this purpose, a clinical trial is defined as any research project that prospectively assigns human subjects to intervention or comparison groups to study the cause-and-effect relationship between a medical intervention and a health outcome. Studies designed for other purposes, such as to study pharmacokinetics or major toxicity (e.g. phase I trials) would be exempt. Further information can be found at www.icmje.org

Studies involving experiments with animals must state that their care was in accordance with institution guidelines. Patients' and volunteers' names, initials, and hospital numbers should not be used.

Supplementary Data
Elsevier now accepts electronic supplementary material to support and enhance your scientific research. Supplementary files offer the author additional possibilities to publish supporting applications, movies, animation sequences, high-resolution images, background datasets, sound clips and more. Supplementary files supplied will be published online alongside the electronic version of your article in Elsevier web products, including ScienceDirect: http://www.sciencedirect.com . In order to ensure your submitted material is directly usable, please ensure that data is provided in one of our recommended file formats. Authors should submit the material in electronic format together with the article and supply a concise and descriptive caption for each file.

Elsevier has a track-record of working on behalf of our authors to ensure authors can always publish in Elsevier journals and still comply with archiving conditions defined in research grant awards.

Open access
This journal offers you the option of making your article freely available to all via the ScienceDirect platform. To prevent any conflict of interest, you can only make this choice after receiving notification that your article has been accepted for publication. The fee of $3,000 excludes taxes and other potential author fees such as colour charges. In some cases, institutions and funding bodies have entered into agreement with Elsevier to meet these fees on behalf of their authors. Details of these agreements are available at http://www.elsevier.com/fundingbodies. Authors of accepted articles, who wish to take advantage of this option, should complete and submit the order form (available at http://www.elsevier.com/locate/openaccessform.pdf). Whatever access option you choose, you retain many rights as an author, including the right to post a revised personal version of your article on your own website. More information can be found here: http://www.elsevier.com/authorsrights.

Authors can specify that they would like to select this option after receiving notification that their article has been accepted for publication, but not before. This eliminates a potential conflict of interest by ensuring that the journal does not have a financial incentive to accept an article for publication.

Proofs
One set of page proofs in PDF format will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent by post). Elsevier now sends PDF proofs which can be annotated; for this you will need to download Adobe Reader version 7 available free from http://www.adobe.com/products/acrobat/readstep2.html. Instructions on how to annotate PDF files will accompany the proofs. The exact system requirements are given at the Adobe site: http://www.adobe.com/products/acrobat/acrrsystemreqs.html#70win.
If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and return by fax, or scan the pages and e-mail, or by post.
Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible to get your article published quickly and accurately. Therefore, it is important to ensure that all of your corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility. Note that Elsevier may proceed with the publication of your article if no response is received.

Offprints
The corresponding author, at no cost, will be provided with a PDF file of the article via e-mail or, alternatively, 25 free paper offprints. The PDF file is a watermarked version of the published article and includes a cover sheet with the journal cover image and a disclaimer outlining the terms and conditions of use. Additional paper offprints can be ordered by the authors. An order form with prices will be sent to the corresponding author.For full instructions on the electronic submission of artwork, please visit the following web address: http://authors.elsevier.com.
