ABSTRACT:
An x-ray cassette including a body having an interior configured to hold a sheet of x-ray film. The body has a window disposed for the transmission of light into the interior of the body. A shutter is mounted on the body. The shutter is free of apertures. The shutter is slideable relative to the window between a closed position, in which the shutter occludes the passage of light through the window, and an open position, in which the shutter is spaced apart from the window to allow the passage of light through the window. A mechanical latch is reversibly translatable between locked and released configurations. The latch in the locked configuration arrests the shutter in the closed position. The latch in the released configuration frees the shutter.
