A scintillation block detector employs an array of optically air coupled scintillation pixels, the array being wrapped in reflector material and optically coupled to an array of silicon photomultiplier light sensors with common-cathode signal timing pickoff and individual anode signal position and energy determination. The design features afford an optimized combination of photopeak energy event sensitivity and timing, while reducing electronic circuit complexity and power requirements, and easing necessary fabrication methods. Four of these small blocks, or 'miniblocks,' can be combined as optically and electrically separated quadrants of a larger single detector in order to recover detection efficiency that would otherwise be lost due to scattering between them. Events are validated for total energy by summing the contributions from the four quadrants, while the trigger is generated from either the timing signal of the quadrant with the highest energy deposition, the first timing signal derived from the four quadrant time-pickoff signals, or a statistically optimum combination of the individual quadrant event times, so as to maintain good timing for scatter events. This further reduces the number of electronic channels required per unit detector area while avoiding the timing degradation characteristic of excessively large SiPM arrays.

Silicon photomultiplier based TOF-PET detector

An implantable subcutaneous device to measure internal body pressure and wirelessly transmit information corresponding to the measured internal body pressure, including a pressure sensor to sense pressure of a particular region of a body of a patient and output a pressure signal corresponding to the sensed pressure, an encoder to receive the pressure signal and encode a signal to produce a sensor information signal to be transmitted to an ex vivo receiver, a transceiver to receive the sensor information signal from the encoder and transmit the sensor information signal to the ex vivo receiver, and a biocompatible housing in which to enclose the pressure sensor, encoder, and transceiver.

Implantable bio-pressure transponder

A device and means of attaching an implantable drainage lumen, catheter, or other device to an internal bodily surface, such as the peritoneum, is generally indicated by a biocompatible material or mesh fabric connected to a lumen, catheter, or other mechanical or electrical device whereby the biocompatible material or mesh may be surgically affixed to a tissue or organ by means of sutures, tacks, screws, tissue infusion or adhesion or other means in order to secure an internal drainage, or mechanical/electrical system or component for the prevention of migration or non-optimal CSF reabsorption after installation.
