Section 2 Publishing Scope

Computerized Tomography (CT) is a technology that, without destroying the structure of an object, uses mathematical methods to reconstruct two-dimensional images on specific layers of an object through computer processing based on the projection data of physical quantities (such as seismic waves, X-rays, etc.) obtained around the object, and forms three-dimensional images based on a series of the above-mentioned two-dimensional images. With the development in CT technology and other disciplines, CT technology now has a wide application in material detection, and has been widely used in medicine, industry, geophysics, engineering, non-destructive testing and other fields. The publishing scope of this journal includes:

Innovative development of CT theory

Cutting-edge progress of CT science and technology

Application of CT technology in detecting the earth's internal structure

Application of CT technology in industry and engineering

Application of CT technology in security check

Medical imaging and image processing

Application of CT technology in medical field

Application of CT technology in archaeology, agriculture and other research domain

4. Figures

● Figures shall be attached, if necessary, which should be scientific, standardized, clear and well designed. The resolute should be 300 dpi at minimum. 

● Heading and number of each figure must be marked clearly. Headings should be in both Chinese and English, and put beneath the figures. Coordinate axis is expressed in "measurement symbol/unit," such as f/Hz, v/(m·s-1). 

● Country borders in maps must comply with national regulation. Notations can be added if necessary.


5. Tables

● A three-line style should be adopted. Auxiliary lines can be added when necessary.

● The number and heading are placed above the tables both in Chinese and English.

● The requirement for measurement symbols and units is the same as for figures.

● Figures and tables could be embedded in text or be submitted in separate files.


6. Statistics and Simulations

● Statistic results should be provided for content involving mathematical statistics or model simulation. For example: "The results of this article are the same/higher/lower compared to literature [1]". The mean test of single sample should be given.

● In comparing the means of two populations, the mean test of independent sample or a paired sample should be given. For example, if the article involves regression model, the model and parameters should be provided, as well as the goodness of fit of the model.


7. References

● Submitted manuscripts should follow the Copyright Law.

● References information must be listed in full when materials, data, methodology, graphics, results, and conclusions are cited.

● The “sequential coding system” should be adopted for description format of the reference documents. For details, please refer to the “Manuscript Template”.

Authors will sign Copyright Transfer Agreement (template can be found at “Download Center”) and agree to transfer the copyright of the article (in any language), including reproduction, distribution, online dissemination, online-first publishing, translation, and compilation (part or all of the article), to the editorial office of Computerized Tomography Theory and Application worldwide free of charge. The editorial office has right to transfer the rights above to a third-party.

2. Computerized Tomography Theory and Application is an open access journal. Once published, all articles will be immediately and permanently available for readers to read and download free of charge.

3. Since 2000, all journal articles have been digitally archived and can be searched and downloaded from the journal website. In order to ensure data security, all information has also been backed up in the editorial office. Before 2000, the hard and soft copy of each issue of the journal had been kept in the editorial office for archiving. In addition, other relevant materials are also kept by the editorial office, such as supplementary information and forms provided by the authors. 


Section 5 Peer Review and Editing

1. The journal adopts blind review system. After submission, the editorial office will conduct a preliminary review of the manuscript. The editorial office will reject the manuscripts which are insufficient in originality, having serious scientific or technical mistakes, lacking valuable information, or not in the scope of the journal. Manuscripts which have passed the preliminary review will be anonymously sent to two or more peer reviewers. Authors must respond to reviewers' every comment and submit the revised version in time. This process would be repeated until reviewers and editors are satisfied with the manuscript. The Editor-in-Chief will conduct the final round of review and the editorial office shall impartially select manuscripts on the basis of academic quality and the review comment.

2. If there is no reply for more than 3 months after submission, it shall be deemed as rejected and authors can re-submit the manuscript to another journal. Authors should keep a copy of the manuscript by their own. The revision of manuscript should be completed within the given time.

3.  The editorial staff / editors / editorial board members should not be involved in publishing decisions on papers which they have written themselves or have been written by their family members or colleagues. Any such submission should be strictly subject to the journal’s usual editorial process. Peer review should be handled independently from the relevant author/editor and their research groups.


Section 6:Correction & Retraction 

Articles published online or in print are considered the final and complete version. In principle, the journal does not make corrections or retractions on published articles. However, in case of the situations described below, corrections or retractions may be carried out if truly necessary.

1. Correction: If there appears to be an unintended scientific mistake in the article which would not lead to significant impacts on the results and conclusion, the editorial office will publish corrections in the journal as soon as possible, detailing the changes made to the original article and indicating the source of the article. The journal will release the corrected new version of the article, and specify the changes to the original article and the date of update. In addition, the superseded version will also be archived. Readers can obtain it directly, but only the latest version of the article should be used for citation.

2. Retraction: In the following cases, the editorial office would retract published articles and issue retraction statements:

(1) If an article is found to have severe scientific errors making the results and conclusion of the article unreliable;

(2) For article suspected of academic misconduct, such as plagiarism and data falsification, the editorial office will initiate an investigation and issue a statement to inform readers of the risks associated with the article. Once the investigation is completed, the result will be made public. If the academic misconduct is confirmed, the article will be immediately retracted and a retraction statement will be issued by the editorial office.
