Abstract: An interconnect subsystem having a sensor, at least one substrate, at least one contact assembly to said sensor and said substrate, and optionally a registration pin connected to said sensor and passing through said substrate. The contact assembly includes a guide tube, a spring within the guide tube, and a transmission tube having a contact surface and at least partially within the guide tube and forced outward by the spring, such that the contact surface contacts conductive pads on the substrate.

Abstract: Some embodiments of the present invention generally relate to a common PET/SPECT/CT gantry including a central aperture. At least one x-ray source can be mounted on the common gantry in a fixed relation, wherein an x-ray beam emitted by the source is directed across the central aperture. Some embodiments can also include a plurality of x-ray scintillation detectors mounted on the common gantry in a fixed relation and directed in an opposing orientation relative to the at least one x-ray source. In some embodiments a plurality of PET/SPECT scintillation detectors is also mounted on the common gantry in a fixed relation, wherein the PET/SPECT detectors define an arc having a center in common with the central aperture.

Abstract: Some embodiments include a low-dose CT apparatus. Such an apparatus can comprise a plurality of x-ray sources disposed on a gantry and spaced apart along a z-axis. The sources may be configured to produce substantially overlapping fan beams, wherein overlap is substantially complete at a detector surface. Some embodiments also include a controller in electronic communication with the plurality of x-ray sources. The controller may be adapted to switch the plurality of x-ray sources between on and off states such that only one x-ray source is in an on state at any time. Furthermore, the controller circuit may be in electronic communication with at least one x-ray detector and may be adapted to synchronize the x-ray detector with the plurality of x-ray sources such that detected x-rays can be matched to an x-ray source.

Abstract: A gamma camera is modified to perform PET studies as well as SPECT studies by utilization of the camera's SPECT electronics to likewise generate triggering pulse signals for photons indicative of a positron annihilation event which are corrected, on a bundled basis, for position, linearity and uniformity by the same digital processors used by the camera for SPECT studies. In addition the triggering pulse signals generate analog timing signals passed through a coarse coincidence circuit to establish matched pairs of timing signals which are digitally time stamped and processed along with the bundled set of pulse signals that the timing signals originated from.

Abstract: A mobile printer having features particularly suited for use in a mobile conveyance such as an airplane. The printer stores a first data set in a memory that is accessed under control of a programmable controller. The printer then receives a second data set via a communications transceiver. Data from the first and second data sets are combined to form a composite bit mapped image which is printed by means of a thermal printhead controlled by the programmable controller.

Abstract: A mobile printer having features particularly suited for use in a mobile conveyance such as an airplane. The printer stores a first data set in a memory that is accessed under control of a programmable controller. The printer then receives a second data set via a communications transceiver. Data from the first and second data sets are combined to form a composite bit mapped image which is printed by means of a thermal printhead controlled by the programmable controller.The thermal printhead uses rolls of thermally sensitive paper which are supported by means of a mandrel roll. The thermal paper is positioned adjacent the print head by means of a platen roll. A biasing force is provided to bias the platen roll away from the print head when a door in the printer housing is opened to provide a space into which the free end of the roll of paper can enter.
