摘要:
Motion artifacts and patient dose during 4D CT imaging are reduced by adaptive control of data acquisition. The respiration signal (310) and CT data acquisition (340) are linked, such that ‘bad’ data from erratic breathing cycles that cause artifacts is not acquired by pausing CT data acquisition (360) when erratic breathing is detected, and not resuming CT data acquisition until steady-state respiration is resumed. Training data is used to develop a tolerance envelope for a respiratory signal such that for erratic breathing cycles the respiratory signal is not within the tolerance envelope (330).
摘要:
The invention relates generally to a process and apparatus for treating biosolids resulting from the treatment of biological wastewater streams. The invention relates to autothermal aerobic treatment of biosolids where temperature is controlled by sensing the oxidation/reduction potential of a treated solution and adjusting the amount of oxygen or the amount of biosolids supplied to the solution. The invention provides for a truly aerobic environment under which thermophilic microorganisms will thrive.

Systems and methods for monitoring and controlling delivery of a therapeutic compound to a brain of a subject using FUS-BBBD are disclosed. The method includes treating the brain of the subject with focused ultrasound in combination with microbubbles for blood-brain barrier disruption (FUS-BBBD), administering the therapeutic agent to the subject; and obtaining a map of a concentration of the therapeutic agent delivered to the brain of the subject using passive cavitation imaging (PCI). The delivery of focused sound may be modulated to match the map of the concentration of the therapeutic agent delivered to the brain of the subject to a desired spatial distribution of the therapeutic agent.
摘要:
The present invention is directed to aqueous based formulations of water-soluble prodrugs of propofol. The formulations comprise in aqueous medium an effective amount of the water-soluble prodrug of propofol and an effective amount of an antioxidant. In one embodiment, the formulation also contains a tonicity modifier. The formulations are particularly useful as intravenous injections. The formulations preferably are buffered to a pH suitable for minimizing degradation of the prodrug during storage. Advantageously, the formulations can be prepared without the use of harmful co-solvents or surfactants, and are stable at room temperature over extended periods of time.

摘要:
A material handling system for placing and retrieving palletized loads in densely spaced storage areas utilizing an overhead bridge crane connected to a pallet load handling device by way of lifting cables and a stabilizing mast assembly. The pallet handling devices may include vertically or horizontally movable pallet engaging fork mechanisms mounted on a generally rectangular frame which is operable to be lowered over a pallet load and engaged therewith by way of the fork mechanisms. The pallet handling device frame may be split and interconnected by actuator mechanisms to facilitate ease of placing the handling devices over a pallet load and releasing the load from the handling device.
