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: 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.

Abstract: A collimator for an imaging detector assembly of a computed tomography imaging system is provided. The collimator includes a collimator module that includes a primary collimation grid having a first edge and a second edge. The primary collimation grid includes multiple radiation absorbing elements spaced apart from each other and configured to provide primary beam collimation. A first radiation absorbing element is disposed on the first edge and a second radiation absorbing element is disposed on the second edge. The collimator module includes multiple plates located on a side of the primary collimation grid and configured to absorb scattered radiation. A respective plate of the multiple plates is disposed over a respective radiation absorbing element of the multiple radiation absorbing elements of the primary collimation grid except the second radiation absorbing element disposed on the second edge of the primary collimation grid.

Abstract: Liquid accumulators and methods for reducing pulsations of a liquid flow are disclosed. A liquid delivery system comprises a pump configured to drive liquid to a pipe. The pipe is configured to transmit a liquid flow. A liquid accumulator is fluidically connected to the pipe. The liquid accumulator comprises a chamber containing the liquid and a vapor column and a power source configured to input energy to the chamber to generate vapor from the liquid to form the vapor column. The vapor column constitutes a gas spring to reduce pulsations of the liquid flow in the pipe. The spring rate of the gas spring can be adjusted by changing the input energy level from the power source to the chamber.
