    Abstract: In one embodiment, a system for thermal management in a CT device comprises first and second thermal management zones, each comprising an x-ray detector, at least one variable speed fan proximate to the x-ray detector, an air temperature sensor positioned to measure an air temperature of the intake air to the variable speed fan, a rail heater in thermal contact with the x-ray detector, a rail temperature sensor in thermal contact with the rail heater to measure a rail temperature, and a controller that controls the variable speed fan as a function of at least the air temperature and the rail heater as a function of the rail temperature to maintain a temperature of the x-ray detector within a predetermined range.

    Abstract: Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, an anesthetic vaporizer includes a sump configured to hold a liquid anesthetic agent; an ultrasonic transducer coupled to a bottom of the sump and at least partially disposed within the sump; a vaporizing chamber fluidically coupled to the sump; and a heating element coupled to the vaporizing chamber and configured to increase a temperature of a surface disposed within the vaporizing chamber.

    Abstract: Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, a system includes an anesthetic agent reservoir, a pump fluidically coupled to the agent reservoir, an injector configured to receive pressurized anesthetic agent from the pump, a vaporizer comprising a heated chamber configured to receive and vaporize the anesthetic agent injected by the injector and supply a mix of the vaporized anesthetic agent and medical gas to a subject via a supply line, and a controller. The controller stores instructions executable to determine a concentration of the vaporized anesthetic agent in the mix and adjust one or more injector parameters based on a difference between the concentration of the vaporized anesthetic agent and a commanded concentration.

    Abstract: CT detector modules are disclosed that include a module frame and a plurality of tileable detector sensors positioned on the module frame. Each of the tileable detector sensors includes an array of detector elements and a mounting structure directly or indirectly coupled to the detector elements to provide for a mounting and alignment of the detector sensor to the module frame. The mounting structure includes an alignment plate positioned generally opposite the array of detector elements, with the alignment plate having alignment pins forming a datum structure to align the detector sensor on the module frame and one or more threaded bosses configured to receive a fastener therein that secures the detector sensor to the module frame. The module frame includes keyed features that receive the alignment pins when the detector sensors are mounted on the module frame, so as to align the detector sensors on the module frame.

    Abstract: Methods and systems are provided for anesthetic agent leakage diagnostics. In one embodiment, a method for diagnosing leaks in an anesthetic vaporizer includes calculating a leakage rate based on measurements of an anesthetic agent level in a sump of the anesthetic vaporizer, the measurements received from a fluid level sensor at a first time and a second time, and outputting a maintenance alert responsive to the leakage rate exceeding a threshold.
