摘要： A finless projectile provides improved ease of use, aerodynamics, muzzle velocity, drag, target, and excursion accuracy, structural integrity, terminal effectiveness and safety, at lower cost. The finless projectile includes a slug, a forward projectile body, an aft projectile body, an obturator, and a pad. The finless projectile is a full bore projectile that defines a hollow core, but does not include a sabot nor does it carry explosives. The finless projectile functions by kinetic energy transfer from the projectile to the target by deforming the target. The center of gravity of the finless projectile is forward of the center of pressure to provide static stability to the finless projectile.

摘要： A method, system, and computer program product for providing textual ultrasound probe position information corresponding to an ultrasound image of a target is described. Based on a user's graphical manipulations of a probe icon relative to a breast icon, a text sequence corresponding to the user's estimate of the position of an ultrasound probe is automatically generated. User error and fatigue are reduced because manual keying of the probe position text sequence is no longer required, and the resulting outputs are standardized in format and therefore more amenable to archiving and electronic analysis. In one preferred embodiment, the user is permitted to select a snapping mode of operation in which the probe icon is snapped to align with a major direction of a preselected coordinate system, further enhancing ease-of-use and reducing user fatigue.

摘要： An adjunctive ultrasound mammography system and associated methods use an adjunctive ultrasound display configured for quick, intuitive, interactive viewing of volumetric ultrasound scans, displayed near a conventional x-ray mammogram display. Preferred navigations among a thick-slice image array, a selected enlarged thick-slice image, and planar ultrasound views are described, including a mode in which the planar ultrasound views are updated in real time as a cursor is moved across an active thick-slice image. In one example the thick-slice images are inverted prior to display, with non-breast areas of the image preferably segmented out and reset to dark. The inverted thick-slice images are of more familiar significance to radiologists as they are more like conventional x-ray mammograms and allow benign features to be more easily dismissed as compared to non-inverted thick-slice images. Preferred embodiments emphasize larger mass lesions and that compensate for mass lesions that straddle thick-slice region borders.

摘要： Endocardial system and method in which noise and artifacts introduced by a simulator are decoupled from a recorder by connecting the stimulator to the electrodes used for pacing and recording only when it is necessary to do so. At other times, the stimulator is disconnected, and low level signals are recorded without interference from the stimulator. In one embodiment, the stimulator is connected only during the time the pacing pulse is being delivered. In another, a stimulator which delivers pacing pulses in response to intrinsic activation of tissue at the pacing site is connected during delivery of a pacing pulse, disconnected during the measurement period which follows, and then reconnected so that it can sense further intrinsic activity and deliver another pacing pulse.

In one preferred embodiment the thick-slice images are inverted prior to display, with non-breast areas of the image preferably segmented out and reset to dark. The inverted thick-slice images are of more familiar significance to radiologists having years of expertise in analyzing conventional x-ray mammograms.

摘要： An adjunctive ultrasound mammography system and associated methods are described, comprising a scanning apparatus for facilitating standardized, repeatable breast ultrasound scans, and further comprising an adjunctive ultrasound display apparatus configured for fast, intuitive viewing of adjunctive ultrasound data concurrently with x-ray mammogram information. In one preferred embodiment, thick-slice ultrasound images are displayed near an x-ray mammogram such that a screening radiologist can quickly view the thick-slice images for assistance in interpreting the x-ray mammogram. Methods for concurrently acquiring and displaying vibrational resonance image (VDI) data are described. Computer-aided diagnosis (CAD) algorithms that incorporate acoustically-based feature vectors are described, the feature vectors including lateral shadow metrics, vertical shadow metrics, posterior enhancement metrics, and VDI-based metrics. Algorithms are also described that combine x-ray mammogram CAD results with adjunctive ultrasound CAD results without requiring complex image registrations therebetween. Many of the practical, economic, and political barriers to acceptance and integration of ultrasound mammography into existing mass breast cancer screening environments are mitigated.

摘要： An instrument guide is described for mounting an invasive instrument such as a biopsy needle to an imaging probe, controlling its position, monitoring its position, and/or predictively displaying its position on a user display of the medical imaging system. A plurality of substantially rigid segments are hingeably connected to the probe, to an instrument handle, and to each other such that movement of the biopsy needle is restricted to within the imaged plane. However, substantial freedom of movement within the imaged plane is provided such that the instrument may be inserted into the patient over a wide range of angles. In one preferred embodiment, angle detectors are provided at each segment intersection and measurements provided for computing and displaying the instrument position and orientation on the user display. The instrument guide/position monitor is preferably made with low-cost components such that it is disposable after a single use. A predictive user display is provided in which the throw of a spring-loaded instrument is shown on the user display, the throw corresponding to the space that the instrument will occupy after a spring trigger is activated.

摘要： Ultrasound mammography in which an automated transducer scans the patient's breast to generate many images of thin slices that are processed into few images of thick slices that can be displayed simultaneously for practical rapid assessment of the breast. The thin-slice images can be acquired by a technician so that a physician need only spend time in assessing the few displayed thick-slice images and, possibly, only a few of the thin-slice images that might match a suspected anomaly indicated in the thick-slice images. Computer-aided detection or diagnosis (CAD) can be performed on the images and resulting mark and/or other information can be displayed as well. Vibration images can be obtained as well and similarly processed and displayed to highlight abnormalities or for other reasons.
