A radiographic imaging device that obtains a radiographic image, includes a battery, a first hardware processor, and a storage. The battery drives the radiographic imaging device. The first hardware processor measures an amount of power remaining in the battery. The storage stores a first threshold and a second threshold of the amount of power remaining in the battery. The first threshold is used to allow photographing of a first photography mode. The second threshold is used to allow photographing of a second photography mode that consumes less power than the first photography mode.

A radiographic apparatus includes: a plurality of detection elements arranged in a two-dimensional fashion; at least one radiation sensor configured to change a signal value to be output, when radiation is emitted thereto; and an irradiation start detecting unit configured to determine whether X-ray emission from an X-ray generator has been started based on the signal value output from the radiation sensor, wherein, when the signal value output from the radiation sensor moves out of a predetermined range, the irradiation start detecting unit does not determine whether the signal value output from the radiation sensor is a signal value outside the predetermined range at least, and when the number of times the signal value output from the radiation sensor moves out of the predetermined range reaches a predetermined number, the irradiation start detecting unit detects a start of X-ray emission from the X-ray generator.

Provided is an X-ray detector including: a data transceiver configured to wirelessly receive identification (ID) information relating to a central controller from the central controller when the X-ray detector is in a sharing mode in which the X-ray detector exchanges certain data with the central controller; and a processor configured to perform a configuration based on the received ID information.

The present disclosure relates to a radiation system. The system may include a treatment assembly, an imaging assembly, a first gantry, and a second gantry. The treatment assembly may include a first radiation source configured to deliver a treatment beam and have a treatment region. The first gantry may be configured to support the first radiation source. The imaging assembly may include a second radiation source and a radiation detector. The second radiation source may be configured to deliver an imaging beam and the radiation detector may be configured to detect at least a portion of the imaging beam. The imaging assembly may have an imaging region. The second gantry may be configured to support the second radiation source and the radiation detector, wherein the second radiation source is located within the second gantry. The treatment region and the imaging region at least partially overlap.

Systems and process are provided to make X-ray radiographs sufficiently quantitative and standardized for bone and other biological material or non-biologic material density evaluations. The X-ray radiograph methodology and system provide a cost effective diagnostic tool that may be used with existing X-ray radiography sources already present in many clinics and hospitals to ultimately produce large volumes of scientifically valid data and useful diagnostic and prognostic information. A calibration bar is added to a conventional X-ray film cartridge and images thereof subsequently incorporated into radiographs for interpretation or a cartridge is designed to integrate a calibration function. The calibration standard affords a standard against which material density is measured. A software program is provided to interpret tissue densities (including bone) to ultimately identify values compared to preselected thresholds.

A radiographing apparatus includes a support base and a housing. The support base includes a base side protruding portion that protrudes towards a bottom surface of the housing. The housing includes a housing side protruding portion that protrudes in a direction toward the support base. A first gap and a second gap are formed between the base side protruding portion and the housing side protruding portion in a perpendicular direction with respect to an incident direction of radiation at different positions. The first gap and the second gap are different from each other in distance in the perpendicular direction between the base side protruding portion and the housing side protruding portion.

A radiation detecting apparatus detects radiation transmitted through a subject. The radiation detecting apparatus includes a hardware processor. The hardware processor detects rotation angles of the radiation detecting apparatus with respect to two mutually perpendicular axes to output angle information, and also detects an orientation of the radiation detecting apparatus. The hardware processor outputs the angle information for the detected orientation.

An electronic cassette has a detection panel in which pixels accumulating charge corresponding to radiation emitted from a radiation source are arranged. A CPU of the electronic cassette transmits and receives a synchronizing signal to and from a radiation source control device. The CPU of the electronic cassette receives a setting notification signal indicating that irradiation conditions have been set from a console. After receiving the setting notification signal, the CPU of the electronic cassette directs the detection panel to start a charge reading operation. The CPU of the electronic cassette transmits an imaging preparation completion signal to the console after a predetermined number of charge reading operations are completed to notify that the predetermined number of charge reading operations have been completed.

A mobile radiographic imaging system includes a mobile radiographic imaging apparatus and a radiographic imaging cassette. The radiographic imaging apparatus includes a displacement mechanism that electrically displaces a radiation emission unit and a displacement mechanism controller that controls the operation of the displacement mechanism. The radiographic imaging cassette includes a remote operation unit that is provided in a housing to remotely operate the displacement mechanism and an operation instruction transmission unit that transmits an operation instruction for operating the displacement mechanism to the displacement mechanism controller in a case where the remote operation unit is operated.

A lockable retainer assembly adapted for retaining or releasing a panel having at least one edge by preventing or allowing movement of an edge of the panel. The lockable retainer assembly includes a rocker rotatably disposed at the edge, the rocker having a slot and is configured to protrude into the panel's path of movement when the rocker is rotatably disposed in a relaxed position. The rocker is configured to clear the panel's path of movement when the rocker is rotatably disposed in a depressed position. A lock is slidingly disposed within the slot and adapted to prevent rotation of the rocker when the lock is disposed in a relaxed position and allow rotation of the rocker when the lock is disposed in a depressed position. In the depressed position, the clears the path of movement of the panel, enabling the panel to be inserted or removed through the path.
