A mobile radiography system includes a moveable arm having an x-ray source attached thereto which can be manually positioned by an operator. A sensor detects a location of a bed or other object relative to the radiography system and generates location information so that a programmable system can restrict lateral movement of the system or arm within a zone proximate the bed or other object.

An x-ray head support boom has a number of tube segments coupled together in series. Each segment may be formed from a flexible membrane and encloses a jammable medium that transitions between a fluidic state and a rigid state in response to an applied force. Each segment is coupled to an actuator for application of the force. At least one cable is coupled to one or more tube segments to apply a tensile force to bend the series of tube segments.

An example scanner positioning control system includes: a display; a processor; and a computer readable storage medium comprising computer readable instructions which, when executed, cause the processor to: output, via the display, a first visual representation of an arrangement of a radiation source, a radiation detector, and a workpiece positioner; identify a change to be made to the arrangement of at least one of the radiation source, the radiation detector, or the workpiece positioner; output, via the display, a second visual representation of the arrangement of the radiation source, the radiation detector, and the workpiece positioner based on the change to be made to the arrangement; and control a scanner positioning system to physically move the at least one of the radiation source, the radiation detector, and the workpiece positioner based on the change.

The present invention relates to X-ray imaging. In order to provide a facilitated and space-saving X-ray imaging apparatus, an imaging arrangement (10) for X-ray imaging is provided that comprises a lower movable support arrangement (12) movably holding an X-ray source (14), and an upper movable support arrangement (16) movably holding an X-ray detector (18). The lower movable support arrangement is configured to be mounted to a floor (20), and the upper movable support arrangement is configured to be mounted to a ceiling (22). The lower movable support arrangement comprises a lower boom (24) rotatably attached to a lower base (26). The lower boom comprises two rotatably connected lower arms (28), and the lower base is rotatable around a vertical axis (30). The upper movable support arrangement comprises an upper boom (32) rotatably attached to an upper base (34). The upper boom comprises two rotatably connected upper arms (36). The rotation axes of the lower boom are arranged horizontally, and the rotation axes of the upper boom are arranged vertically.

A compression tube attaching-detaching unit is provided with an arm, a connecting pin, and an attaching-detaching mechanism portion. The arm supports a compression tube. The attaching-detaching mechanism portion is removably coupled with the connecting pin to mount the arm on a radiographic fluoroscopic imaging apparatus. The connecting pin has a shaft portion and a flange portion positioned at the tip end of the shaft portion. The attaching-detaching mechanism portion includes a main body, a lid portion, a locking portion, and an unlocking portion.

A tomosynthesis scanning system includes an X-ray emitter connected to a first robotic device, and an X-ray detector connected to a second robotic device. The first robotic device moves the emitter along a first spiral trajectory path and, optionally, the second robotic device moves the detector along a second spiral trajectory path during the scanning process. Where both the emitter and detector move, the movement is synchronized. A computer is used to control the first and second robotic devices. In operation, an object to be scanned is positioned between the X-ray emitter and the X-ray detector, then the X-ray emitter is moved alone, a first spiral path while emitting a photon beam at the X-ray detector and allowing the photon beam to pass through, the object before reaching the X-ray detector, Attenuation of the photon beam reaching the X-ray detector is measured and an image is produced based on the measured attenuation of the photon beam.

A medical image diagnostic system of an embodiment includes a processing circuit which is configured to control transition between a plurality of steps included in a workflow for examining a subject. The processing circuit is configured to acquire first information representing a preparation state of the subject in a first step among the plurality of steps, is configured to acquire second information representing permission for transition from the first step to a second step, and is configured to control transition from the first step to the second step on the basis of the first information and the second information.

An imaging apparatus and associated methods are provided to efficiently estimate scatter during multi-fraction treatments for improved quality and workflow. Estimated scatter from one fraction during a treatment course can be utilized during subsequent fractions, allowing for measurements with higher scatter-to-primary ratios. The quality of scatter estimates can be maintained, while workflow improves and dosage decreases. Scan configuration limits can be utilized to maintain a minimum level of scatter measurement quality. Patient information can be monitored to ensure that prior fraction scatter estimates are still applicable to current patient status.
