Patent ID: 8086014

Claim:
An X-ray image diagnostic apparatus that irradiates a subject with X-rays and transmits multiple captured images obtained by imaging the subject to a control apparatus, the X-ray image diagnostic apparatus comprising: a first calculation unit configured to calculate the transmission amount that can be transmitted per unit of time; an obtainment unit configured to obtain conditions, out of the imaging conditions present when imaging the subject, that relate to the data amount of each captured image and the number of captured images captured per unit of time; a second calculation unit configured to calculate the respective resulting data amounts when a captured image captured under the conditions obtained by the obtainment unit is compressed at first and second compression rates; a determination unit configured to mix the captured images compressed using the first and second compression rates and determine the mix ratio so that the transmission amount per unit of time when the multiple captured images are transmitted is less than the transmission amount calculated by the first calculation unit; and a transmission unit configured to transmit the multiple captured images compressed using the first and second compression rates at the ratio determined by the determination unit.
