A nuclear medicine infusion system may be used to generate and infuse radioactive liquid into a patient undergoing a diagnostic imaging procedure. In some examples, the infusion system includes a frame that carries a radioisotope generator that generates radioactive eluate via elution. The frame may also carry a beta detector and a gamma detector. The beta detector can be positioned to measure beta emissions emitted from the radioactive eluate supplied by the generator. The gamma detector can be positioned to measure gamma emissions emitted from a portion of the radioactive eluate to evaluate a safety of the radioactive eluate delivered by the infusion system.

Radioisotope delivery system with multiple detectors to detect gamma and beta emissions

An infusion system may include a strontium-rubidium radioisotope generator that generates a radioactive eluate via elution, a beta detector, a gamma detector, and a controller. The beta detector and the gamma detector may be positioned to measure beta emissions and gamma emissions, respectively, emitted from the radioactive eluate. In some examples, the controller is configured to determine an activity of rubidium in the radioactive eluate based on the beta emissions measured by the beta detector and determine an activity of strontium in the radioactive eluate based on the gamma emissions measured by the gamma detector.

Electrical stimulation devices and systems for safely operating such devices

A printed circuit board connector for orthogonal mating of two or more printed circuit boards. The connector utilizes interior perimeter trace connections of a main printed circuit board and internal trace connections of a mating printed circuit board in conjunction with external trace connections. The main board may utilize surface connections, where both external trace connections and internal trace connections are exposed on a surface of the main board to couple to the mating board. The main board may include a slot or pocket, allowing for the partial insertion of the mating board into the main board, with internal trace connections disposed within the slot or pocket. The slot or pocket may extend through the main board, such that the internal trace connections are disposed along a side of the pocket to couple with corresponding internal trace connections of the mating board.

A shielding assembly may be used in a nuclear medicine infusion system that generates and infuse radioactive liquid into a patient undergoing a diagnostic imaging procedure. In some examples, the shielding assembly has multiple compartments each formed of a shielding material providing a barrier to radioactive radiation. For example, the shielding assembly may have a first compartment configured to receive a radioisotope generator that generates a radioactive eluate via elution, a second compartment configured to receive a beta detector, and a third compartment configured to receive a gamma detector. In some examples, the compartments are arranged to minimize background radiation emitted by the radioisotope generator and detected by the gamma detector to enhance the quality of the measurements made by the gamma detector.

A sensing device includes a printed circuit board (PCB) having a conductive trace. A micro-controller is attached to the conductive trace and data transmission means is connected to the micro-controller. A sensor is embedded within the PCB and is connected to the micro-controller via the conductive trace. The sensor is configured to sense at least one physiological parameter in a patient.
