A multimodal system for breast imaging includes an x-ray source, and an x-ray detector configured to detect x-rays from the x-ray source after passing through a breast. The system includes an x-ray detector translation system operatively connected to the x-ray detector so as to be able to translate the x-ray detector from a first displacement from the breast to a second displacement at least one of immediately adjacent to or in contact with the breast. The system includes an x-ray image processor configured to: receive a CT data set from the x-ray detector, the CT data set being detected by the x-ray detector at the first displacement; compute a CT image of the breast; receive a mammography data set from the x-ray detector, the mammography data set being detected by the x-ray detector at the second displacement; and compute a mammography image of the breast.

The present invention relates to a head immobilization system for immobilizing a patient's head in a supine position of the patient, the system comprising: a support rail structure adapted to be coupled to a patient rest and extending at least on both lateral sides of the patient's head, a mask frame adapted to be coupled to at least one deformable upper mask sheet, wherein the mask frame is releasably connected to the support rail structure via a first interface section and a second interface section, with at least two pins protruding from the first interface section in a first direction, and at least two pin-receptions provided at the second interface section, wherein each one of the pin-receptions receives one of the pins, and a catch-mechanism for each pin-reception and each corresponding pin, which allows the pin to be pushed further into the pin-reception in the first direction, but which interlocks in case of an attempted withdrawal of the pin from the pin-reception in a second, opposite direction.

A holding device wherein: a holding tool including a curved and rigid surface formed in accordance with a shape of a body surface of a body part of a subject along with an adhesive layer having adhesiveness to a skin surface of the subject on the curved and rigid surface side; an elongated arm member having one end portion to which the holding tool is attached; and a fixing tool for fixing the arm member to a fixed object, attached to an end portion of the arm member on the side opposite to the end portion on the side to which the holding tool is attached.

An extra-oral dental imaging apparatus can obtain a radiographic image of a portion of a head of a patient. Exemplary dental apparatus and/or method embodiments can position a subject for dental radiographic imaging by providing a bitable dental arch mounting apparatus to offset the antero-posterior plane of the dental imaging apparatus and the plane of symmetry of the dental arch mounting apparatus. In one embodiment, the offset can be provided by a tilted dental arch mounting apparatus (e.g., relative to the horizontal).

Systems for immobilizing a patient are disclosed. The system includes at least one preform formed from a low melting temperature thermoplastic, the preform being configured to be formed to the anatomy of the patient, at least one frame coupled to the at least one preform, and at least one support configured to support the anatomy of the patient. The system also includes at least one lock mechanism coupled to at least one of the frame and the support and configured to couple the at least one frame to the at least one support, and at least one adjuster mechanism coupled to at least one of the at least one frame and the at least one support and configured to selectively adjust a distance between the at least one frame and the at least one support while the at least one frame is coupled to the at least one support.

A patient support system includes independently adjustable end columns supporting a centrally hinged, jointed or breaking patient support structure. At least one column includes a powered rotation assembly. The patient support includes at least two sections. A coordinated drive system provides for both upwardly and downwardly breaking or jointed orientations of the two sections in various inclined and tilted positions. Cable, cantilevered and pull-rod systems are included.

An ankle imaging accessory is provided by the present invention, particularly an ankle positioning device to facilitate the taking of X-ray views of a patient who had sustained an ankle fracture. The ankle imaging accessory is made from an X-ray translucent material and includes heel supports on which heels of a patient can locate. A pair of spaced apart stops defines the limits of an arc on which a foot pivoting on the heel support can move.

The present disclosure relates to an auxiliary apparatus used to capture an image of teeth of a patient, and more particularly, to a support block that enables an image of teeth of the patient to be captured in a state where a natural dentition is maintained, and an imaging apparatus including the same. According to the dental support block of the present disclosure and the imaging apparatus including the same, imaging can be performed by reflecting a patient's normal occlusal state, thereby accurately checking and diagnosing a condition of teeth, dentition, and the like and treating accordingly.

The present invention relates to a method for positioning a patient's body part including a target to be irradiated relative to an irradiation source of a radiation imaging device, that generates a radiation beam directed towards the target, the method being constituted to be executed by a processor of a computer and comprising the following steps: receiving, at the processor, geometry data describing the geometry of at least one structure located in the field of view of the radiation imaging device; receiving, at the processor, tracking data describing the spatial position of the at least one structure within the field of view of the radiation imaging device; determining, with the processor, position data incorporating the geometry data and the tracking data, describing whether a position of the at least one structure lies within a radiation beam trajectory through the target; determining, with the processor, repositioning data describing a position of the at least one structure away from the radiation beam trajectory through the target; outputing, from the processor, the repositioning data allowing for repositioning of the at least one structure. The present invention further relates to a corresponding computer program and system.

A patient positioning unit for an extra-oral imaging system can include a pair of elongated arm extending parallel to a first direction, each elongated arm including an engaging surface along a medial side between a first end and a second end, first and second temporal holding members, each operatively coupled to a second end of one elongated arm, and a sliding member having an engaged surface along at least two contacting sides, the sliding member mounted between the engaging surfaces near the first end of each elongated arm, where each of the engaged surfaces contacts one of the engaging surfaces.
