The rotation mechanism rotates the plurality of imaging units around a body axis of the subject. The radiation source elevating mechanism and the detector elevating mechanism change an interval between the plurality of imaging units in a rotation axis direction. An imaging control unit of the CPU controls operations of the plurality of imaging units, the rotation mechanism, the radiation source elevating mechanism, and the detector elevating mechanism.

An acquisition unit of an image processing device acquires a radiographic image which includes a patient and markers including lead plates and has been captured in a state in which the markers are disposed at a first position between a radiation source and the patient and a second position between a radiation detector and the patient, the subject being interposed between the first and second positions. An image processing unit calculates a correction magnification for setting a part of interest in the patient included in the radiographic image to a set dimension, on the basis of sizes of images of a plurality of the markers included in the radiographic image and an actual size of the markers, and changes a size of the radiographic image according to the correction magnification.

A radiation detector has a sensor panel unit which includes two sensor panels and in which end portions of the two sensor panels are arranged to overlap each other in a thickness direction. An image processing unit acquires two projection images from the two sensor panels. A combination unit of the image processing unit performs a process related to image quality on the projection image in a case in which a tomographic image which is a diagnosis image to be used for a doctor's diagnosis is generated and does not perform the process related to image quality on the projection image in a case in which a scout image which is a confirmation image for confirming a reflected state of the subject is generated.

A CT apparatus includes a radiation source that emits radiation, a radiation detector that detects the radiation, an annular frame to which the radiation source and the radiation detector are attached and in which a subject is positioned in a bore, and three columns that hold the frame to be movable up and down in a vertical direction.

Medical image capturing apparatus

A radiography apparatus includes an upright imaging stand that is used for radiography on a subject, a camera as a detection sensor that immediately detects a state of the subject with respect to the upright imaging stand, a tablet terminal, and a reflective member. The tablet terminal displays a notification screen including an image output from the camera. The reflective member reflects the notification screen such that the subject facing the upright imaging stand visually recognizes the image.

Radiography apparatus

A radiation detector includes a sensor panel unit, a support table to which the sensor panel unit is attached, and two fixing members. The sensor panel unit includes two sensor panels. The sensor panel has pixels that sense visible light converted from radiation and generate charge. The sensor panel unit has a configuration in which an end portion of one sensor panel and an end portion of the other sensor panel are arranged to overlap each other in a thickness direction. A first fixing member fixes two sensor panels in an overlap region in which the end portions overlap. A second fixing member fixes the sensor panel unit and the support table in the overlap region. The second fixing member at least partially overlaps the first fixing member in the overlap region in a plan view of the sensor panel unit in the thickness direction.

Radiation detector and radiography apparatus

A radiation detector includes a support table in which an attachment surface having an arc surface shape is formed, a sensor panel which has a rectangular plate shape and in which pixels that include TFTs and detect radiation are two-dimensionally arranged, a circuit board, a flexible cable, and a reduction structure. The sensor panel is attached to the attachment surface while being curved following the arc surface shape. The flexible cables connect a curved side of the sensor panel and a reading circuit board and are arranged along the curved side. The flexible cable is bent to dispose the reading circuit board at an angle of 90° with respect to the sensor panel. The reduction structure reduces a bias of a stretching force applied to the flexible cable caused by the curved side.

A radiation detector includes a support table, a sensor panel, a fixing member, and a contact member. An attachment surface having an arc surface shape is formed in the support table. The sensor panel has an imaging region in which a plurality of pixels detecting radiation are two-dimensionally arranged. A first surface of the sensor panel is attached to the attachment surface following the arc surface shape. The fixing member partially fixes the first surface to the attachment surface. The contact member comes into contact with a second surface of the sensor panel which is opposite to the first surface to suppress the lifting of the sensor panel from the support table.

The specification unit specifies a kind of the object in the color image. The estimation unit estimates intensity of radiation in an environment captured in the color image based on reference information including the distance image and a specification image as a specification result of the kind of the object.

In the radiography system, a camera image of the usage environment in which the electronic cassette is used is captured. An in-image cassette region of the electronic cassette is detected from the camera image. The cassette ID of the electronic cassette is acquired from the in-image cassette region.

A position detection unit is disposed at an exposure position that is included in a camera image and a field of view of a camera and outputs a position signal indicating the position of a part of a peripheral portion of an electronic cassette. The calculation unit calculates an in-image cassette position which is the position of the electronic cassette in the camera image, on the basis of the position, direction, and size of the position detection unit in the camera image and the position signal. A composite image generation unit generates a composite image of the camera image and a cassette frame indicating the in-image cassette position.
