Abstract: A PET or SPECT radiation detector module (50) includes an array of detectors (54, 58) and their associated processing circuitry are connected by a flexible cable having releasable connectors. A method of mounting and dismounting includes mounting a radiation detector array in a support structure in a diagnostic scanner, connecting one end of a flexible connector to the detector array, and connecting the other end of the flexible connector to its associated circuitry.

Abstract: Receive circuits and associated methods are provided for ultrasound imaging. Both subarray mixing and time division multiplexing are provided with a same circuit. Components of the receive circuit respond to either phasing or time slot information to implement subarray mixing or time division multiplexing. A network of switches allows combination of signals from different elements to form different sub-apertures. A controller minimizes power consumption while outputting the desired phase or time division multiplexed information by gating a clock to various registers. Each of the registers corresponds to different groups of transducer elements. For loading new phasing information, the clock is turned on to the desired register. Duration operation of the receive circuit, the clock is gated off. The register outputs the previously loaded values in a static state without clocking.

Abstract: A method of generating a filter (40) for a nuclear medicine system (20) where the filter selects valid detected radiation events for image processing. A dataset (60) is provided that is indicative of a plurality of emitted radiation events occurring over a predetermined period of time. Signals representative of the response of a detector to the dataset of the plurality of emitted radiation events are generated. A pattern is determined (66) based on a correlation of a plurality of signals resulting from the response of the detector to a plurality of single radiation events in the dataset. A filter is generated (74) based on the correlation pattern. A method and apparatus of using the generated filter is also disclosed.

Abstract: An apparatus for cleaning conduits which includes a generally cylindrical body (12) having a bore adapted at one end for connection with a high pressure fluid source. The body includes a groove (26) extending circumferentially about the exterior of the body. The body further includes a port (28) which extends through the body from the bore to the groove. The conduit cleaning apparatus further includes an annular rotor (32) having a central rotor bore (34). The annular rotor is positioned about the body for rotation thereon. The annular rotor further includes at least one orifice (46) extending through the annular rotor from the bore to the exterior of the annular rotor. The orifice is positioned in communication with the groove when the annular rotor is positioned for rotation on the body. The conduit cleaner apparatus further includes a wire (48) attached to the annular rotor. The wire is manufactured from braided stainless steel wire, and is highly abrasive and shearing to objects which it contacts.
