    摘要: A gamma camera is modified to perform PET studies as well as SPECT studies by utilization of the camera's SPECT electronics to likewise generate triggering pulse signals for photons indicative of a positron annihilation event which are corrected, on a bundled basis, for position, linearity and uniformity by the same digital processors used by the camera for SPECT studies. In addition the triggering pulse signals generate analog timing signals passed through a coarse coincidence circuit to establish matched pairs of timing signals which are digitally time stamped and processed along with the bundled set of pulse signals that the timing signals originated from. The timing signals in turn are corrected from a mapped detector head look up table on the basis of the corrected position of the triggering pulse signal and the time lag between each matched timing signal pair passed through a fine coincidence window processor thus insuring that the line of response passing through the corrected, precisely established positions of scintillations that produced the triggering pulse signals occurred within a time period clearly indicative of a positron annihilation event. By counting only true LORs images having high resolution can be constructed even though the camera's detecting heads cover a limited solid angle of event detections. The timing correction table is generated from an improved calibration technique which factors out those inherent time delays, including signal noise and jitter, which are specific to that gamma camera.

    摘要: A mobile printer having features particularly suited for use in a mobile conveyance such as an airplane. The printer stores a first data set in a memory that is accessed under control of a programmable controller. The printer then receives a second data set via a communications transceiver. Data from the first and second data sets are combined to form a composite bit mapped image which is printed by means of a thermal printhead controlled by the programmable controller.The thermal printhead uses rolls of thermally sensitive paper which are supported by means of a mandrel roll. The thermal paper is positioned adjacent the print head by means of a platen roll. A biasing force is provided to bias the platen roll away from the print head when a door in the printer housing is opened to provide a space into which the free end of the roll of paper can enter. A cam is provided on the underside of the door to close the gap between the platen roll and the print head when the housing door is closed so that the platen roll presses the paper against the print head while the printing operation takes place. A back pressure acts on the paper upstream of the platen and idler rolls to straighten the paper with respect to the print head.

The controller may be adapted to switch the plurality of x-ray sources between on and off states such that only one x-ray source is in an on state at any time. Furthermore, the controller circuit may be in electronic communication with at least one x-ray detector and may be adapted to synchronize the x-ray detector with the plurality of x-ray sources such that detected x-rays can be matched to an x-ray source.
