Dear Modeler,
The purpose of the atlas is to reproduce an accurate model of the human anatomy.
Particular techniques are used to meet the needs of a functional 3D atlas of anatomy, but what matters most is the attention to the anatomical dimension.
The two essential missions are:
-to correct the existing objects following the error reports made by the anatomists
-to complete the missing anatomical structures, using the same principles
The file weight and RAM needed to display it is essential:
If the file is too heavy, it won't run on many devices.
Professional anatomists will report the errors that need to be fixed in a spreadsheet.
Anatomical books, images, should be used as reference.
Many other questions regularly arise; here are the first attempts to explain the particular techniques used in the .blend file.
To discuss what to do and share your suggestions and/or contributions, you can answer to this post.
The two following subjects also concern the 3D Modelers:
Create a FEMALE MODEL
Create ANIMAL MODELS

Hello ! I want to contribute as 3D Modeler. Can someone guide me through how and what I've to do for further process!?
Dear Mr Siddhpura,
This list shows you which parts are missing in the atlas (when columns A and B are white). You may want to use this viewer to see the hierarchy.
In the future, the errors will be reported in red (column D) with a description.
The two techniques that you will need the most are the use of curves for all the vessels and nerves (see 'Curves') and the Labeling process ('Labels').
When you will have modified or created new objects/labels, you'll be invited to share them (PasteAll or else) and I will merge them in the main file and update it on the website.
This is the first collaboration on the 3D content of the project and it will allow to establish the best practices.
Ideas about what to begin with:
-new eyebrows, the medulla and its content, glans of penis, the oral cavity and pharynx, the temporal bone and its relations, etc.
There is much anatomical expertise to do by yourself for the moment but I hope that anatomists will soon provide comments and images to guide our work.
These comments would then describe the modification needed in the corresponding part of the spreadsheet.
Hello ! First of all many thanks for warm welcome. And now I'll come to the topic.
I'm not getting what all we've and where to start. As a modeler do you mean to design from scratch ?
In my opinion, I would suggest to bring up all anatomical details from actual patient data. Like, CT, MRI data...
Hoping you're getting me. I'm Actually a Implant Designer in Blender and Also I'd demonstrated history in medical Imaging for segmentation of medical data into 3D.
So, I'm confuse in between your provided information.
Thanks & Regards,
Deven
You can view my recent work for Medically segmented data from medical imaging at this link. I'd done this for my company.

SO, Here you could check the level of Accuracy in all the data. Even we'd segmented MRI data so well so we can get vasculature data in depth.
You raise the central question:
Where is the .dicom used for reference?
Answer: I have no idea.
The segmentation of a .dicom allows to generate anatomically accurate meshes.
To match the atlas' needs (weight, visual aspect), these meshes will probably have to be decimated, remeshed.
The lack of .dicom reference is an important inconvenient.
If you feel like creating models from scans, the functions made to use Blender as an anatomy-viewer are available for you to share them.
I would sometimes like to have segmented meshes to use them as reference, but it is quite a complicated process (segment, export, remesh, adapt, integrate).
Although it is not a conventional way of working for the radiologists, anatomy illustrators are forced to accept a certain degree of approximation in order to produce the illustrations. The same compromise has been accepted in the creation of the 3D model of the Atlas.
Please read the post about creating a female model for more information.
Your meshes could be directly used for the Open anatomy project, though, and be used as reference for the model shared on Z-Anatomy.
