Abstract: A framework for power management. The framework includes at least one power distribution board disposed within a radio-frequency (RF) cabin of a medical imaging system and coupled to an external reference clock. The power distribution board may include a clock circuit that generates one or more output clock signals based on a reference clock signal from the external reference clock. One or more switching regulators may be coupled to the clock circuit. The one or more switching regulators may be synchronized to the one or more output clock signals and provide power to one or more endpoint loads.

Abstract: Systems and methods include an analog-to-logic circuit and a digital processing component. The analog-to-logic circuit receives a first electrical signal, outputs a first logic signal indicating whether or not a voltage of the first pulse is greater than a first threshold voltage, and outputs a second logic signal indicating whether or not the voltage of the first pulse is greater than a second threshold voltage. The digital processing component receives the first logic pulse and the second logic pulse, determines, based on the second logic signal, if the first pulse is valid, and determines, based on the first logic signal, a first trigger time associated with the first pulse.

Abstract: A displacement mechanism for placing an optical device onto a patient's eyes and removing the optical device from the patient's eyes when the patient is located in a patient bore of a medical imaging system. The mechanism includes a pneumatic device and a resilient element attached between an inner surface of the patient bore and the optical device wherein the resilient element extends through the pneumatic device and wherein the optical device is spaced apart from the patient's eyes in a first position. A pump inflates the pneumatic device to move the optical device to a second position wherein the optical device is placed on the patient's eyes. Inflation of the pneumatic device extends the resilient element and biases the resilient element to return to the first position. A vent valve vents air from the pneumatic device to return the optical device to the first position.

Abstract: Systems and methods include determination of a first relationship between change in photopeak energy and event time skew based on a first detection event signal acquired from a detector at a first temperature and a subsequent detection event signal acquired from the detector at a next temperature, acquisition of a subsequent detection event signal from the detector, determination of an event time associated with this detection event signal, determination of an event time skew based on an energy of this detection event signal and the first relationship, determination of a corrected event time based on the event time and the event time skew, and identification of a coincidence based on the corrected event time.

Abstract: A method is for determining a heating effect of an imaging sequence of a second imaging modality on a detector of a first modality of a combined imaging device in dependence of a reference imaging sequence of the second imaging modality. A further method is for compensating a heating effect of an imaging sequence of a second imaging modality on a detector of a first modality of a combined imaging device. Furthermore, a combined imaging device includes a magnetic resonance imaging device and a first modality including a detector and a temperature compensation unit configured to compensate for a temperature variation of the detector. The combined imaging device is configured to perform a method for determining a heating effect of an imaging sequence of the magnetic resonance imaging device on the detector of the first modality in dependence of a reference imaging sequence of the magnetic resonance imaging device.

Abstract: Systems and methods for a positron emission tomography (PET) kit are described. A PET detector kit may include a gantry, a plurality of PET detector modules, and an event processing device. A PET detector module may include a housing, a crystal, a light detector, and a communication component.
