Handheld X-ray scanner

A radiation scanning system comprises a radiation detection sub-assembly, and a routing sub-assembly coupled to the radiation detection sub-assembly. The radiation detection sub-assembly comprises a first substrate electrically connected to the radiation detection sub-assembly, and a second substrate electrically connected to the first substrate. The radiation scanning system further comprises one or more radiation shields between the first substrate and the second substrate, and one or more semiconductor dice electrically connected to the second substrate on a side of the second substrate opposite the first substrate. Related radiation detector arrays radiation scanning systems are also disclosed.

An x-ray imaging apparatus includes a holdable housing; an x-ray source mounted within the housing and configured to output a fan beam of x-rays; and a hoop chopper wheel rotatably mounted within the housing and comprising an x-ray attenuating material configured to block x-rays of the fan beam. The hoop chopper wheel defines a set of beam apertures of which each aperture is configured to pass therethrough a corresponding angular portion of x-rays from the fan beam, so that rotation of the hoop chopper wheel causes scanning of the corresponding angular portion of x-rays. The x-ray source may be a transmission-type x-ray tube configured to output the fan beam centered in an x-ray extraction direction forming an angle greater than 0 degrees with respect to a longitudinal axis of the x-ray tube.

A radiation scanning system comprises a radiation detector configured to measure at least some radiation. The radiation detector comprises an arc portion exhibiting a semicircular shape, the arc portion comprising a plurality of facets on a side thereof, a detector module coupled to each facet, the detector module comprising a base portion comprising a first substantially planar surface in contact with the facet, a detector unit coupled to a second substantially planar surface of the base portion, the second substantially planar surface parallel with the first substantially planar surface, and a cooling structure in thermal communication with a side of the arc portion opposite the plurality of facets. Related radiation detectors and radiation systems are also disclosed.

A detector array for a radiation system includes a radiation detection sub-assembly, a routing sub-assembly, and an electronics sub-assembly. The routing sub-assembly is disposed between the radiation detection sub-assembly and the electronics sub-assembly and includes one or more layers of shielding material. For example, the routing sub-assembly may include a printed circuit board having embedded therein a shielding material configured to shield the electronics sub-assembly from at least some radiation. In some embodiments, the shielding material defines at least one opening through which a conductive element(s) passes to deliver signals between the radiation detection sub-assembly and the electronics sub-assembly.

Among other things, an anti-scatter collimator is provided including a first layer defining a first retaining member at a first surface. A second layer defines a second retaining member at a first surface that faces the first surface of the first layer. A septum is disposed between the first layer and the second layer and physically contacts the first retaining member and the second retaining member. The first retaining member and the second retaining member maintain a position of the septum relative to the first layer and the second layer. The septum has a third attenuation coefficient that is greater than a first attenuation coefficient of the first layer and a second attenuation coefficient of the second layer. An end support is attached to the first layer and to the second layer. The end support borders an end of the septum.
