Abstract: A scan completeness auditing system for screening a volume of tissue comprising a manual image scanning device having an imaging probe, a position tracking system configured to track and record the position of the imaging probe during use, and a controller in communication with the recording system and the manual image scanning device, the controller configured to electronically receive and record the scanned images from the manual image scanning device, and to measure an image-to-image spacing and a scan-to-scan spacing between the scanned images within scan sequence and between scan sequences respectively. The scan completeness auditing system is further adapted to provide an alert to the operator if the image-to-image or scan-to-scan spacing exceeds an acceptable value.

Abstract: A scan completeness auditing system for use with an ultrasound imaging console in screening a volume of tissue comprising a location tracking system comprising at least one position sensor adapted to couple to an imaging probe and at least one orientation sensor adapted to couple to the probe, the position and orientation sensors configured to provide data corresponding to the position and orientation of the imaging probe and a receiver comprising a controller configured to receive the position and orientation data from the location tracking system and to electronically receive and record a first scan sequence comprising a first set of scanned images representing cross-sections of the tissue from the imaging probe. The controller can be configured to assign a replay dwell time to each image in the scan sequence. The dwell time for each image can be based on a relative spacing for that image in the scan sequence.

Abstract: A scan completeness auditing system for use with an imaging console in screening a volume of tissue comprising a position tracking system configured to track and record a position of a manual imaging probe. The position tracking system com prises a plurality of cameras adapted to couple to the manual imaging probe and configured to provide position data for the manual imaging probe. The scan completeness auditing system includes a receiver comprising a controller-configured to electronically receive position data for the manual ultrasonic imaging probe from the position tracking system and to electronically receive and record a first scan sequence comprising a first set of scanned images representing cross-sections of the tissue from the manual imaging probe. The controller can be configured to compute an image-to-image spacing between successive images within the first scan sequence and to determine whether the computed image-to-image spacing exceeds a maximum limit.

Abstract: Systems and methods are disclosed for reviewing multiple images while monitoring a reviewer's attentiveness during the review. Systems include an image review system configured to output a series of images to the display and a user attention monitoring system configured to monitor at least one attention parameter for a user during the user's review and to generate user attention data based on the at least one attention parameter monitored, wherein the image review system is configured to output the second image to the display if the user attention data indicates sufficient user attentiveness. The image review system may also be configured to generate distraction or review breaks during the review period.

Abstract: Total ammoniacal concentration (TAC) in blood is measured and displayed on a repetitive basis by a controller driven sensor arrangement which may be utilized either with a catheter structure or with a bypass system. The catheter based sensors may be employed with a peripheral region of the vascular system of the body. Repetitive measurements are carried out and these measurements are subjected to a moving average filtering procedure, whereupon the filtered TAC values are displayed numerically and graphically. The controller functions to compute the rate-of-rise of TAC and compares that value with a threshold rate-of-rise valuation which is inputted by the practitioner. Threshold values for TAC also may be inputted and the system not only provides alarm warnings for threshold excursions in TAC above threshold or excursions in rate-of-rise of TAC above threshold but also provides a visual cuing as a warning that TAC is elevating from one filtered measurement to the next.

Abstract: Cardiac output is measured utilizing a catheter in conjunction with the indicator dilution technique. Non-thermal analyte-containing fluid is used as the injectate. This fluid is biocompatible with and metabolizable within the body of the patient. An analyte concentration sensor is mounted upon the catheter and located downstream within the bloodstream from the port from which the analyte-containing fluid is expressed. Because of the matching of rapid concentration sensor response with an analyte-containing fluid which is metabolizable, the measurement of cardiac output may be carried out as often as about one to three minutes in conjunction with an infusion interval substantially less than the measurement frequency interval. The analyte-containing fluids are selected from a group consisting of ammoniacal fluid, heparin, ethanol, a carbon dioxide releasing fluid, glucose, and anesthesia agent.

Abstract: A radio frequency tissue ablation apparatus for use on a horizontal support surface in connection with a medical procedure on a patient. A portable carrying case having a carrying handle is provided and is adapted to rest upon a horizontal surface. The portable carrying case has a cover with an inner surface and is movable between a generally vertical open position and a generally horizontal closed position when the portable carrying case is resting on the horizontal support surface. The portable carrying case has a keyboard and a primary display panel disposed adjacent the keyboard under the cover when the cover is in a closed position and is accessible visually and physically when the cover is in an open position. The primary display panel includes a plurality of groups of numerical indicia and a plurality of switches associated with at least certain of the groups of numerical indicia for establishing criteria for those certain groups of numerical indicia.

Abstract: The present invention provides a package for and method of packaging a sterilizable calibratable medical device including a hydratable sensor component. The device is maintained in a sterile environment during storage and in a clean environment during the calibration procedure. The package includes a manifold connected to the sensor component by plumbing. The plumbing establishes fluid communication between the manifold and the sensor component and/or between the sensor component and the ambient environment of the plumbing. The manifold, plumbing and medical device are sealed in a wrap including a gas-permeable surface. The wrap and its contents, including the interior surfaces of the components, are sterilizable by exposing the wrap to a gaseous sterilization solution and appropriately adjusting the plumbing. The medical device is hydratable by directing the hydration solution to the sensor component by means of the plumbing.
