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.

Disclosed is a patient positioning assembly for orientating a patient with respect to a radiation source. The patient positioning assembly includes a translatable member movable in a vertical direction between a vertically downwards first position and a vertically upwards second position. The patient positioning assembly further includes a patient support assembly mounted to the translatable member and adapted to rotate relative to the translatable member about a vertical axis. The patient support assembly is configurable between a first orientation, which sustains the patient in a seated position, and a second orientation, which sustains the patient in a generally standing position.

A scatter radiation protection device is provided. The scatter radiation protection device includes a barrier that is movable in an x-direction, a y-direction, and a z direction; a skirt that is movable in an x-direction; and a sliding track having an upper surface and a lower surface. The barrier and the skirt are configured for connection to the sliding track, and the barrier and the skirt provide for at least 0.5 millimeters of lead (mmPb) equivalence.

A system of shields designed to provide substantially greater protection, head to toe, against radiation exposure to health care workers in a hospital room during procedures which require real-time imaging. The shields are placed around the patient and the x-ray table and provide protection even when the x-ray tube is moved to various angles around the patient.

An apparatus for Digital Imaging in the Head Region of a Patient includes an X-ray source and an X-ray sensor, supported on i a rotary arm supported on a structure by a motor driven translation and rotation means. The rotary arm is provided with adjustment means for varying the distance between the source and the sensor. The apparatus comprises a single sensor for both panoramic imaging and computed tomography, and has a control unit, that controls the source, the sensor, the adjustment means, and the translation and rotation means and operates the apparatus in a basic operation mode for bigger patients and in an alternative operation mode for smaller patients, in which the distance between the source and the sensor is reduced as compared to the distance used for the basic operation mode.

An X-ray imaging apparatus is provided. The X-ray imaging apparatus includes an X-ray source configured for irradiating X-rays to a subject; a filtering unit configured for controlling a dose of X-rays irradiated to the subject; and a processor configured for distinguishing and setting up an uninterested region in an X-ray image obtained based in the irradiated X-rays, and for controlling the filtering unit to set a dose of X-rays irradiated into the uninterested region.

The disclosure relates to a system and method for medical imaging. The method may include: move, by a motion controller, a phantom along an axis of a scanner to a plurality of phantom positions; acquire, by a scanner of the imaging device, a first set of PET data relating to the phantom at the plurality of phantom positions; and store the first set of PET data as an electrical file. The length of an axis of the phantom may be shorter than the length of an axis of the scanner, and at least one of the plurality of phantom positions may be inside a bore of the scanner.

An example portable radiography scanning system includes: a radiation detector configured to generate digital radiography images based on incident radiation; a radiation emitter configured to output the radiation; and a computing device configured to: receive the digital radiography images from the radiation detector; compensate one or more of the digital radiography images for variations in magnification of the digital radiography images; and store one or more compensated radiography images based on the magnification compensation and associated with physical location information.

A method for fluoroscopy energizes a radiation source to form a scout image on a detector and processes the scout image to determine and report a radiation field position with respect to a predetermined zone of the detector. The radiation source is energized for fluoroscopic imaging of a subject when the reported radiation field position is fully within the predetermined zone.

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.
