Brain stem anatomy and safe entry zone learning app

"Brain view" is an app developed by the University of Tokyo Department of Neurosurgery that allows you to intuitively learn the anatomy of the brain stem and the safe entry zone (SEZ: a safe area for approaching the brain stem).

Conventional textbooks and anatomy books are limited to two-dimensional display, and internal nerve fibers and nerve nuclei can only be learned by observing the cross sections of the midbrain, pons, and medulla oblongata only in pieces. Although it was difficult to grasp the real three-dimensional space of, it is possible to freely and intuitively operate in a "brain view" that allows you to freely rotate, magnify, and see through a three-dimensional understanding. I will.

The development of the three-dimensional model of the brain stem is based on 3DCG created by Dr. Yukinari Kakizawa (Red Surgery, Suwa Red Cross Hospital).

Rotate or enlarge/reduce the display by dragging or pinching the screen, and tap the anatomical structure to make it semi-transparent/transparent and display the inner nerve fibers and nerve nuclei.

SEZ has collected information from 20 publications on PubMed (1982 to 2019) and displayed 14 types and 24 areas in total. Tap on the SEZ to highlight important relevant structures and view typical surgical approaches, complications, and relevant information gathered from the literature along with citations.

In lesion mode, virtual lesions can be displayed as purple spheres/ellipsoids. The size and position of this virtual lesion can be set arbitrarily, and the shape of a sphere/ellipsoid can be changed. For example, it is possible to examine the surgical approach by displaying lesions that mimic actual cases in the clinical setting.

The scenes examined in this way can be saved in the library with the scene registration button, and the saved scenes can be instantly called by tapping the scene browsing button.
