摘要： An image processing apparatus includes a first hardware processor that calculates an exposure index related to noise of a radiographic image based on image data of the radiographic image. The first hardware processor creates a density histogram of a region of interest set in the entire radiographic image or a part of the radiographic image, extracts a plurality of pixels having signal values within a specific range from the created density histogram, analyzes variations in the signal values of the plurality of extracted pixels, and calculates the exposure index based on an analysis result of the variations.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
