Abstract: An electronic cassette comprises a main battery which is detachably attached to a battery loading unit, and a sub-battery which supplies electricity to a bias power circuit and so on in substitution for the main battery. A power source selector changes the power source to the sub-battery from the main battery when it is judged that a replacement operation of the main battery is started. Since supply of the electricity to the bias power circuit is continued, and the bias voltage continues being applied to a photoelectric converter without a break, there is no need to perform a photoelectric conversion stabilizing process and an offset correction image detecting process after turning on of the main power. Therefore, a start-up time TR2 is largely shortened from a start-up time TR1.

Abstract: An ultrasound diagnostic apparatus includes a head-mounted display that is mounted on a head of a user and has a camera unit configured to acquire a view image obtained by imaging a field of view in front of the user, and a puncture needle length calculation unit (46) that, in a case where at least a part of the puncture needle is imaged by the camera unit, recognizes the puncture needle by performing image analysis on the view image, and calculates a length of the puncture needle in the view image.

Abstract: A radiographic image captured by irradiating a subject with radiation is acquired. A scattered radiation removal unit removes a scattered component from the radiographic image using at least imaging conditions. A correction information acquisition unit acquires correction information for correcting the degree of removal of the scattered component and changes the imaging conditions on the basis of the correction information. The scattered radiation removal unit performs a process of removing the scattered component from the radiographic image on the basis of the changed imaging conditions.

Abstract: An image obtaining unit obtains a subject image, a body thickness distribution modifying unit receives input of a virtual model having an estimated body thickness distribution and modifies the estimated body thickness distribution of the virtual model to output the modified estimated body thickness distribution, and a body thickness distribution determining unit determines the outputted estimated body thickness distribution to be used as the body thickness distribution of the subject. The body thickness distribution determining unit includes a judging unit for switching, according to a judgment condition, between a first control under which the body thickness distribution modifying process is iteratively executed until a first termination condition is satisfied and a second control under which the body thickness distribution modifying process is iteratively executed until a second termination condition that is different from the first termination condition is satisfied so that the first control or the second control is executed.

Abstract: A center position of a female connector is located near to a rear surface of a housing compared with a center position of the housing in a thickness direction of the housing of an electronic cassette. An inclined surface, which is inclined relative to a side surface and the rear surface of the housing, is formed between the side surface and the rear surface. The female connector is formed on the inclined surface. Therefore, it is possible to attach an outer grid provided with a longer side panel to the housing, in comparison with the case where the center position of the female connector is made coincident with the center position of the housing in the thickness direction of the housing, without requiring any processing.

Abstract: It is detected whether a grid stripe is present in a radiographic image. In a case in which the grid stripe is detected, a process of removing the grid stripe from the radiographic image is performed and the radiographic image is displayed. In a case in which the grid stripe is not detected, a process of removing a scattered component from the radiographic image is performed and a radiographic image subjected to the scattered radiation removal process and a radiographic image before the process are displayed.

Abstract: A derivation unit acquires imaging conditions corresponding to order information received by a receiving unit based on a table stored in a storage unit and sets the imaging conditions in a radiation source control unit. The radiation source control unit controls a radiation source based on the set imaging conditions such that a radiographic image is captured. An acquisition unit acquires the actual values of the imaging conditions from the radiation source control unit. The derivation unit derives virtual grid characteristics based on the actual values of the imaging conditions. An execution unit acquires a captured radiographic image through a detector control unit. The execution unit performs a virtual grid process for the acquired radiographic image based on the virtual grid characteristics derived by the derivation unit and the acquired imaging conditions to generate a radiographic image from which the influence of scattered radiation has been removed.

Abstract: An electronic cassette comprises a main battery which is detachably attached to a battery loading unit, and a sub-battery which supplies electricity to a bias power circuit and so on in substitution for the main battery. A power source selector changes the power source to the sub-battery from the main battery when it is judged that a replacement operation of the main battery is started. Since supply of the electricity to the bias power circuit is continued, and the bias voltage continues being applied to a photoelectric converter without a break, there is no need to perform a photoelectric conversion stabilizing process and an offset correction image detecting process after turning on of the main power. Therefore, a start-up time TR2 is largely shortened from a start-up time TR1.
