摘要： A pressure measuring device includes a resilient expandable pressure sensor element having an open end and an opposite closed end. The pressure sensor element includes spiral flutes extending between the open and closed ends defining spiral bellows. The pressure sensor element is tapered over at least a portion of its length from the open end to the closed end. The pressure measuring device also includes a supporting structure having a pressure indicating scale. The supporting structure holds the pressure sensor element such that the open end of the pressure sensor element is in communication with a fluid whose pressure is to be measured and pressure applied by the fluid causes the pressure sensor element to expand axially and be visibly displaced relative to the pressure indicating scale by a distance related to the pressure applied by the fluid.

摘要： A system and method for determining the temporal resolution of a tomographic imaging device uses an apparatus to drive one or more dynamic phantoms composed of multiple materials. The apparatus is placed at or near the isocenter of the imaging device and the one or more phantoms are moved to produce a plurality of dynamic features, each having a specified frequency. The dynamic features are imaged with the device and the acquired image data corresponding to the dynamic features is analyzed to determine a temporal modulation transfer value at each of the known specified frequencies. The temporal resolution of the imaging device is determined using these temporal modulation transfer values.
