Abstract :
A Monolithic Active Pixel Sensor (MAPS) prototype device for real-time dosimetry in brachytherapy application is presented. A novel charge sensitive element is used for pixel design. It features a built-in charge-to-current conversion and allows operation mode with charge integration. The two 32/spl times/32 pixel arrays prototype design in a standard CMOS process is presented.
