摘要： A crystal containing detector particularly suited for use in immunoguided surgery capable of detecting gamma emissions present at tumor sites. The instrument utilizes a cadmium-zinc-telluride detector crystal which may be retained within a finger mount positioned over the surgeon's finger. Within this mount there also is incorporated a first preamplification stage designed to accumulate charge signals from the detector as well as to drive a relatively short length of cable to a second preamplification stage located, for example, within a housing at the surgeon's upper arm. The small finger mounted probe may be moved between operative orientations at the underside of the tip of the finger to stand-by orientations at the top of the finger adjacent the knuckles. In an additional embodiment, the finger probe incorporates a sodium iodide crystal, the scintillations from which are transmitted via a short length of fiber optic cable to an upper arm mounted housing which contains a photomultiplier tube. Signals from the remote, arm-mounted housing then are transmitted via longer cabling or the like to a control console.

摘要： A simulator arrangement wherein visual cues are generated by a video system at a display surface (18) spaced from an eye position (14). The image at the display surface is formed as longitudinal boundaries emanating from a vanishing point (VP) positioned a predetermined distance above a fixed horizon (30) image. Hue and texture visual information are developed between the longitudinal boundaries from a memory function (178). The slopes of the longitudinal boundaries are developed as the quotient of the value of the transverse displacement of a boundary from the corresponding position of the eye position divided by a value representing simulated height of the eye position. The arrangement finds particular utilization in conjunction with flight trainers.

摘要： System and apparatus particularly suited for tracking a radiopharmaceutical present within a lymph duct and locating a sentinel node within which the radiopharmaceutical has concentrated. A smaller, straight, hand-held probe is employed carrying two hand actuable switches. For tracking procedures, the probe is moved in an undulatory manner wherein the location of the radiopharmaceutical containing duct is determined by observing a graphics readout developed preferably employing a circularly accessed data memory. When the region of the sentinel node is approached, a switch on the probe device is actuated by the surgeon to carry out a sequence of squelching operations until a small node locating region is defined. At that point in the procedure, the straight small probe will be pointed at and in adjacency with the radiopharmaceutical containing sentinel node. The probe-mounted switches are configured to apply preset current levels upon the probe pre-amplifier power supply. These levels are detected, identified by a discriminator and emulating signals are generated. A sterilizable remote switch provides a squelch threaded level trim function.

摘要： Intended for use in a pathology laboratory, the apparatus includes a multi-segment crystal array over which is positioned a platform supported receiving region with a pattern carrying indicia emulating and in registry with the pattern of the crystal array segments. The tissue carrying a radiolabeled locator is positioned on the receiving region and the photon emission count values for each segment are compiled and displayed at a computer monitor or as a print-out in conjunction with crystal segment identification. Observation of the count values by a pathologist then shows the location over a segment of highest count value at which locator is more likely to be concentrated. Sectioning then is carried out at that location.

摘要： The method for identifying a sentinel lymph node located within a grouping of regional nodes at a lymph draininage basin associated with neoplastic tissue wherein a radiopharmaceutical is injected at the situs of the neoplastic tissue. This radiopharmaceutical migrates along a lymph duct toward the drainage basin containing the sentinel node. A hand-held probe with a forwardly disposed radiation detector crystal is maneuvered along the duct while the clinician observes a graphical readout of count rate amplitudes to determine when the probe is aligned with the duct. The region containing the sentinel node is identified when the count rate at the probe substantially increases. Following incision, the probe is maneuvered utilizing a sound output in connection with actuation of the probe to establish increasing count rate thresholds followed by incremental movements until the threshold is not reached and no sound cue is given the surgeon. At this point of the maneuvering of the probe its detector will be in adjacency with the sentinel node which then may be removed.

摘要： A flight simulator arrangement wherein a conventional, movable base flight trainer is combined with a visual cue display surface spaced a predetermined distance from an eye position within the trainer. Thus, three degrees of motive freedom (roll, pitch and crab) are provided for a visual proprioceptive, and vestibular cue system by the trainer while the remaining geometric visual cue image alterations are developed by a video system. A geometric approach to computing runway image eliminates a need to electronically compute trigonometric functions, while utilization of a line generator and designated vanishing point at the video system raster permits facile development of the images of the longitudinal edges of the runway.
