A dynamic imaging quality control device performs quality control of dynamic imaging in which a dynamic state of a subject is imaged by irradiating the subject with radiation. The device includes a hardware processor that generates quality information regarding a quality of the dynamic imaging by using at least two frame images among multiple frame images constituting a dynamic image obtained by the dynamic imaging and outputs the quality information.

An image processing apparatus includes a hardware processor that acquires image data of a radiograph, calculates an exposure index related to noise in the radiograph on the basis of the image data that is acquired, and causes a notifier to notify of a matter based on the exposure index that is calculated.

A radiography system includes an image former, a first determiner, and an operation controller. The image former performs serial radiography of repeatedly generating a frame that constitutes a video. The first determiner determines whether a next test action is the serial radiography. The operation controller makes the image former begin turning a switch element on/off in a same manner as a manner in the serial radiography before start of the next test action in a case where the first determiner determines that the next test action is the serial radiography.

An exposure record totalizer includes: a hardware processor that adds up a first exposure record of a first exposure image and a second exposure record of a second exposure image, when a radiography system generates the first exposure image through first exposure and the second exposure image through second exposure, and that links information about a third exposure record to a third exposure image generated on the basis of the first exposure image and the second exposure image, the third exposure record being generated by the hardware processor.

An imaging control apparatus includes a hardware processor. The hardware processor is capable of sending, to a console, a command indicating permission of radiation emission. The console controls a radiation emitting apparatus that emits radiation. The hardware processor is also capable of outputting a first control signal to a radiographic imaging apparatus that generates a radiograph based on the first control signal.

A radiation generation control device includes an acquirer, a first connector, a second connector and a controller. The acquirer acquires a first signal which instructs emission of radiation. The first connector inputs a second signal which indicates a driving state of a radiography apparatus that generates a radiographic image. The second connector connects with a radiation generation apparatus that generates radiation. The controller makes the second connector repeatedly output a third signal which instructs emission of radiation with a predetermined period based on the acquired first signal and the input second signal.

A radiation image imaging apparatus includes the following. A switch is in an off state if off voltage is applied to the connected scanning line, is in an on state if charge generated in the radiation detecting element is accumulated in the radiation detecting element and the on voltage is applied to the connected scanning line. A hardware processor controls the scanning driver to apply the on voltage to a plurality of adjacent scanning lines at the same time to obtain an image in which a binning number in an extending direction of the signal line is larger than a binning number in an extending direction of the scanning line. The hardware processor performs an enlarged interpolation process on the obtained image to generate an image in which a pixel size in the extending direction of the signal line matches the extending direction of the scanning line.

Radiation image imaging apparatus and radiation image imaging system

A tomography system includes a radiation source, a radiation detector, a subject table, an imaging unit and a reconstruction unit. The imaging unit obtains a projection image a predetermined number of times while changing a positional relationship of the radiation source and the radiation detector. The reconstruction unit generates a tomogram of a subject using the projection image obtained by the imaging unit. The reconstruction unit includes a correction unit. The correction unit performs correction processing to (i) create a profile of a pixel signal value from a no-subject-included projection image obtained by the imaging unit without the subject on the subject table and (ii) correct, on the basis of the created profile, a subject-included projection image obtained by the imaging unit with the subject on the subject table or a detection probability used in generating the tomogram.
