METHOD AND APPARATUS FOR OBTAINING VOLTAGE INFORMATION BASED ON CHARGE PACKETS THAT ARE INPUT DIFFERENT TIMING

摘要

A voltage obtaining device comprises; a plurality of conversion units which convert each charge packet into voltage and are connected to each other in parallel; and a control unit which controls a time point when the charge packet is inputted to each of the conversion units. When an operation of a (n-1)^th conversion unit is completed, the control unit controls the time point so that the charge packet is inputted to an n^th conversion unit. The n means the number of the conversion units. According to the present invention, a processing speed of a photon counting detection (PDC) device can be improved.
