摘要： A reference image of a patient may be generated. A subsequent x-ray image of the patient may be generated after the generating of the reference image where the subsequent x-ray image is associated with a low dosage. A difference between the reference image and the subsequent x-ray image that is associated with the low dosage may be determined. A motion of the patient may be identified as having occurred based on the determined difference.

摘要： A signal relay device comprises a first connection I/F, to which an emission switch is connected, a second connection I/F, to which an emission signal I/F of an electronic cassette is connected, and a third connection I/F, to which a switch I/F of a source control device is connected, and a signal processing unit. The signal processing unit generates an emission execution signal during a time period in which an emission command signal from the emission switch and an emission enable signal from the electronic cassette are inputted. The source control device drives an X-ray tube to allow X-ray emission while the emission execution signal is inputted.

摘要： An X-ray diagnosis apparatus detects X-rays output from an X-ray source and transmitted through a subject, and generates images of the inside of the subject, and comprises a detector, an X-ray intensity distribution data generator, and an entrance dose distribution data generator. The detector detects the intensity of the X-rays output from the X-ray source. The X-ray intensity distribution data generator generates X-ray intensity distribution data showing the X-ray intensity for each of a plurality of subdomains of an X-ray irradiation field from the X-ray source based on the detection outcome by the detector. The entrance dose distribution data generator generates entrance dose distribution data showing the dose of X-rays output from the X-ray source and irradiated onto the subject, based on the X-ray intensity distribution data.

摘要： A console acquires a displacement amount of an X-ray source from a displacement amount detector. In the case where an electronic cassette having an image detector is not appropriately positioned with respect to a body part to be imaged, a position of the X-ray source is changed in accordance with a position of the body part to be imaged. A dose measurement field position determining unit specifies a current relative position between the X-ray source and the electronic cassette having the image detector based on a displacement amount. The dose measurement field position determining unit determines a position of a dose measurement field based on the specified current relative position.

摘要： An AEC unit of an electronic cassette sets a dose target value and a short-circuited pixel used for AEC based on a radiographing condition. When a control unit of the electronic cassette detects start of irradiation of X rays, the AEC unit starts integration of a cumulative dose of X rays which are incident to a target region based on a dose detection signal output by the short-circuited pixel. The AEC unit predicts a stop timing at the time point t1, waits until the time point t2 which is a predetermined time earlier than a scheduled stop time, and sends a stop timing notification to an X-ray generation device at the time point t2. When the stop timing notification is received, a X-ray source control device immediately inputs an irradiation stop command so as to stop an operation of an X-ray source.

摘要： A method for sensing a level of ionizing radiation directed from a radiation source through a subject and toward an imaging detector, the method executed at least in part by a logic processor, obtains positional coordinate data that is indicative of at least a portion of the subject to be exposed to radiation and that defines a radiation measurement area relative to the subject. The method assigns one or more sensing elements to sense radiation within the radiation measurement area. A measurement signal is acquired from each of one or more assigned sensing elements.
