Paper Abstract

A medical imaging camera with an avalanche-type image pickup tube (HARPICON) was developed for digital radiography. The camera obtains high quality images even at low doses because its sensitivity is as much as 32 times higher than that of a conventional pickup tube camera. The camera also has a wide dynamic range and a high signal-to-noise ratio because of HARPICON's gamma characteristic.
