Abstract
A computed tomography scanner having a brake which is automatically engaged in the event dynamic motor braking fails to stop scanner motion. Within a predetermined range of motion two brake mechanisms are employed. One has a brake shoe to contact a braking surface and stop rotation of the scanner in one direction and a second has a second brake shoe which stops rotation in an opposite direction. The brake shoes are engaged and retracted by a cam surface which as the scanner rotates, moves into contact with one of two bearings connected to associated ones of the brake shoes.
