PORTABLE RADIOLOGICAL IMAGE CAPTURING APPARATUS AND RADIOLOGICAL IMAGE CAPTURING SYSTEM

WIPO Patent Application WO/2010/073838

A1

Provided are a portable radiological image capturing apparatus and a radiological image capturing system wherein the battery waste and the break of bias lines or the like can be prevented and wherein excess charges can be sufficiently removed from radiation detecting elements.  The portable radiological image capturing apparatus comprises: a plurality of radiation detecting elements that are two-dimensionally arranged and located in the respective areas defined by scan lines and signal lines; a bias power supply that applies a bias voltage to the radiation detecting elements via bias lines; switching means that are associated with the respective radiation detecting elements; a scan driving means that controls the voltage to be applied to the switching means, thereby controlling the on/off states of the switching means; and a battery.  During a reset process for discharging excess charges from the radiation detecting elements, the scan driving means controls the voltage to be applied to the switching means via the scan lines, thereby restricting the outflows of currents from the radiation detecting elements to the bias lines.
