[EN] FOBOS™ (Forensic Body Scanner) is a diagnostic digital radiology system designed for forensic pathology. The system is designed to allow non-stitched whole-body, AP and lateral, x-ray images in under a minute.
The system’s design allows for automatic full-body x-ray image capture without moving or touching the body. High penetration capability for bodies up to 550 lbs.
“Smart” filters allow for improved visualization of the body, thus creating conditions for more reliable detection of injuries and anomalies. The filters provide: a) Reduced noise from X-ray images and b) Automatic contrast adjustments of x-ray images.
An optional radiation protection cabin allows the system to be safely used in any room/location.
My responsibilities:
Communication between PC and Controllers via TCP (developed own protocol).
Designed CAN-bus for controllers and motors.
Control driver via CANOpen protocol (DS402)
Developed own CAN protocol for communication between Universal Controllers in the project.
