From my work experience with Panasonic. I had a chance to work a 3D Anatomy project. Th main purpose of the project is education. It is a simulation software for the anatomy of the body and allows you to dive in different layers. I think this type of project classifies as class 1. however not sure which department is responsible for such a project, is it CDRH? Because it is learning software and not really a medical device. you can search the product on Google. Also, there is simulation videos on youtube.
