A radiation detector includes an image generator and a case. The image generator generates a radiograph according to received radiation. The case stores the image generator and includes a first component and a second component screwed to the first component. The second component is movable with respect to the first component in a direction along a seat surface of a screw by a screw hole of the second component being formed such that a diameter is larger than a diameter of a shaft of the screw but smaller than a diameter of a head of the screw. A loosening torque that acts, in a direction to loosen the screw, on the screw when the seat surface receives a frictional force from the second component is smaller than a loosening start torque that is the loosening torque of when the screw starts to loosen.

In one example, a medical imaging system comprises: a gantry; and a laser mount including: a first section fixedly coupled to the gantry; a second section seated within the first section and slideable within the first section; and a third section seated within the second section and rotatable within the second section, the third section adapted to house a laser radiation source.

A bracket body releasably secures a compression element to the compression arm of a breast imaging system. A pair of parallel lateral arms extends from a rigid frame which extends from the bracket. A span connects the ends of the lateral arms opposite the bracket and a flexible membrane extends from the span towards the bracket body.

A digital dental x-ray sensor device includes a rounded, three-dimensional housing that lacks corners, edges, or other relatively sharp features that are known to cause discomfort when used in a patient's mouth. The rounded housing can be spherical, ellipsoid, or any similar regular or irregular rounded shape, and can be formed by ensuring that all curves of the surface of the rounded housing have a minimum radius that is sufficient to prevent features that can dig into the soft tissue of the inside of a patient's mouth.

The invention relates to a combined detector (660) comprising a gamma radiation detector (100) and an X-ray radiation detector (661). The gamma radiation detector (100) comprises a gamma scintillator array (101.sub.x, y), an optical modulator (102) and a first photodetector array (103.sub.a, b) for detecting the first scintillation light generated by the gamma scintillator array (101.sub.x, y). The optical modulator (102) is disposed between the gamma scintillator array (101.sub.x, y) and the first photodetector array (103.sub.a, b) for modulating a transmission of the first scintillation light between the gamma scintillator array (101.sub.x, y) and the first photodetector array (103.sub.a, b). The optical modulator (102) comprises at least one optical modulator pixel having a cross sectional area (102′) in a plane that is perpendicular to the gamma radiation receiving direction (104). The cross sectional area of each optical modulator pixel (102′) is greater than or equal to the cross sectional area of each photodetector pixel (103′.sub.a, b).

A hybrid medical apparatus having an imaging unit, an irradiation unit, and a patient support apparatus is provided. The imaging unit is configured to record image data of an examination region. The irradiation unit is configured to carry out an irradiation of at least a part of the examination region. The imaging unit and the irradiation unit have a common isocenter. The irradiation unit is arranged for rotational movement along a first perimeter independently of the imaging unit. An X-ray source and an X-ray detector of the imaging unit are arranged for movement such that a central beam between the X-ray source and the X-ray detector runs through the common isocenter. The patient support apparatus and/or the imaging unit and/or the irradiation unit is movable along a first spatial axis such that the examination region of the examination object is able to be arranged in the common isocenter.

An X-ray apparatus and patient instruction system for easily instructing patients through an X-ray procedure in a variety of languages includes an X-ray apparatus, a computer, and a controller. The X-ray apparatus comprises an X-ray generator coupled within an X-ray housing to create a digital X-ray image. An X-ray CPU and a speaker are coupled within the X-ray housing. The computer comprises a computer CPU coupled within the computer housing. The computer CPU is in operational communication with the X-ray CPU stores a plurality of audio recordings of X-ray procedure instructions to play through the speaker. A computer display shows the digital X-ray images from the X-ray generator. The controller comprises a control button coupled to the controller handle to operate the speaker and the X-ray generator.

A tethered laparoscopic probe is provided, the tethered laparoscopic probe for deployment through a trocar into a cavity of a subject to detect gamma radiation from a radiopharmaceutical administered to the subject. The laparoscopic probe comprises a probe head shaped for insertion through the trocar and configured to be freely moveable within the cavity. The probe head comprises an elongate casing comprising radiation shielding for inhibiting gamma radiation from passing through the probe head, the radiation shielding having a detection aperture for admitting gamma radiation. The probe head further comprises a gamma radiation detector arranged within the casing, the gamma radiation detector configured to detect gamma radiation through the detection aperture of the casing. The probe head further comprises means for, in use, facilitating the localization of a source of radiation from the radiopharmaceutical within the cavity. The laparoscopic probe further comprises a tether coupled to the probe head and for, in use, tethering the probe head through the trocar.
