Fluoroscopic image capturing apparatus

A fluoroscopic image capturing apparatus comprising:

• a timing control device configured to output an irradiation timing signal in synchronization with a drive timing signal for driving a specimen or a timing signal as a detection result of an operation of the specimen;
• an electromagnetic wave generation unit configured to irradiate, in synchronization with the irradiation timing signal, the specimen with a pulsed electromagnetic wave beam having a wavelength with which the electromagnetic wave beam is transmitted through the specimen;
• and
• an electromagnetic wave detection device configured to receive the electromagnetic wave beam transmitted through the specimen,
• wherein the electromagnetic wave generation unit includes a plurality of pulse generation units configured to generate a plurality of voltage pulses having different periods and different pulse widths, and an electromagnetic wave beam irradiation unit configured to generate the electromagnetic wave beam according to any of the plurality of voltage pulses.
