The site is a structured database of medical studies, stored in DICOM format. You can download any study and add a study to the archive database yourself. The studies archive contains medical visual images in DICOM format as individual files (archives) – zip- and rar- documents, with a name in the form of a sequence number (according to the number of addition). The structure of the archive is based on the compared classification of diseases between pathoanatomical manifestations and clinical classifications, in order to reflect all possible visual changes and determine their situation in the general structure of diseases. The archive of medical images of different pathological processes is designed for demonstration of visual manifestations of diseases, pathological and syndrome-based changes, as well as certain anatomical changes and variants on the images obtained with various radiological methods. The archive can be used openly for both educational and scientific purposes. All information is in free and paid access for users of the site. It is allowed to use the archival data of medical images for research purposes, publication and educational demonstrations. The studies archive of this site contains impersonal data of patients, which is achieved by automatic deletion of data from each study at the moment of uploading studies to the site. Home page
The top panel is a set of icons that reflect the structural organization of the “Diagnosis Tree”. By clicking on them you can go to the section of interest with automatic sorting of studies in a table, according to the selected section and subsection. The top panel also includes a tool called “Filter” that allows to sort the studies and show them in the table.

The table is an organized list of studies, structured according to the addition of studies to the site archive. The table contains a sequence number of a study (by order of addition), drop-down bar, age of the patient, information about the presence of this study in the group of other studies (in a metastudy), date of creation and date of the study, nickname of the user who added this study, method of the study, area of study, chosen diagnosis, note of the cost of the study and attributes.
Main elements of the table
The drop-down bar includes the option “Edit”, by clicking on which the author of the study can edit it and other users can visualize the main parameters of the study and see a screenshot, as well as the presence of attached files and see a detailed diagnosis. The option “Download” - allows downloading the study in DICOM format in a zip-archive. The option “Preview” allows opening the study in the on-line DICOM viewer.
“I” element is a pop-up table with a brief description of the study and a miniature screenshot with the main data of the study.
Attributes are symbolic abbreviations: the number reflects the number of downloads, the letter E reflects the Caucasian race (it can be also the Negroid and the Mongoloid race– N and M, respectively), the symbol of sex (male/female), the subjective reliability level established by the author, which reflects the confidence in the correct diagnosis, as well as a mark of public access (the globe) are added after moderation (the mark is in the form of an upward arrow before the moderation).
The filter is a tool for filtering studies in the table. It is possible to set and change all the available parameters of the table in the filter.

On-line DICOM viewer is equipped with the minimum necessary number of tools for viewing and analyzing the images of DICOM files.
A metaexamination means a group of several examinations by a common feature. Such feature can be the studies performed natively and the studies after contrast enhancement, which should be combined for convenient search. It is also possible to combine studies for dynamic observation of the course of a disease during the treatment (several studies with a different time range), studies of different areas of the same patient’s body and other reasons for grouping.
The general view of Metaexamenations includes the examination number, date of creation and “i” symbols with the possibility to open a drop-down box with a miniature image and a brief characteristic.

You can delete the added diagnosis by clicking on the “-“ button. Open a “Diagnosis Tree” by clicking on the button with a pencil. If there is a convincing picture on the methods of visualization or verification of the pathological process, it is recommended to mark the section “Diagnosis (Microscopy)”.
The assignment of diagnosis is made by selecting one position in the so-called “Diagnosis Tree” - a structured set of pathologies, collected by combining and comparing clinical, pathoanatomical and radiological classifications.
The section “Microscopy” includes “Histology” for designation of changes in the tissue cells and “Microbiology” for designation of an infectious agent.
The next panel includes the selection of the study method, which also has a hierarchical structure of location of the elements of methods, a panel for selecting a subjective level of reliability of the diagnosis, the selection of the location of the place of study.

The site administrator guarantees the safety, non-disclosure and non-distribution of your study during the moderation process. Studies that do not undergo moderation:
- Studies containing information about the patient that cannot be deleted automatically.
- Studies with attached documents, containing information about the patient and/or medical staff.
- Studies located in the folders with names similar to the last name or first name of the patient.
- Studies containing DICOM-files not associated with this Diagnosis.
- Studies in this database, added by another user.
Reasons for refusal of public access to the study (failure to pass the moderation):
- Content of information about the patient that cannot be deleted automatically, for example:
- Folders in the uploaded file that contain information about the patient must be renamed.
- Images in DICOM format that contain information about the patient must be deleted:
Remarks to the moderation – all administrator’s requirements when returning the study to the user without opening public access will be summarized in the comments or sent to e-mail with the study number, because the administrator cannot personally change the data chosen by the user. After the correction, the user must send the study for moderation again or delete it, change on his/her computer, recreate an archive, download to the site and send it for moderation with a note (in the comments) about the correction of the previous inconsistencies.
Completion of moderation (obtaining public access). After a positive decision of the administrator about the conformity of the user’s study with the rules of filling in and publication on the site, a globe icon appears in the attributes on the user's page “My studies”.
When opening this study, its page will look like the rest of public studies:
