摘要:
A scanning unit for inspecting objects comprises in one example a radiation source, a movable platform to support an object, and a detector positioned to receive radiation after interaction of radiation with the object. The platform is movable at least partially within a cavity defined, at least partially, below at least one of the source or the detector. In another scanning unit, a first conveyor conveys an object to a movable platform, and second and third conveyors convey the object from the platform. The second and third conveyors are at different vertical heights. In another scanning unit, images from an energy sensitive detector and a spatial detector are fused. In a method, scanning parameters during CT scanning are changed and images reconstructed before and after the change. In another method, an object is scanned with X-ray beams having first and second energy distributions, generated by the same X-ray source.

摘要:
The present invention generally provides improved devices, systems, and methods for measuring materials with NMR and/or MRI. Exemplary embodiments provide a sensor array for NMR mapping of the material. For example tissue can be measured with the sensor array mounted on a probe body having a distal portion which can be inserted through a minimally invasive aperture. While many tissues can be measured and/or diagnosed, one exemplary embodiment includes a probe adapted for insertion into a lumen of a blood vessel. The sensor array can provide improved spatial resolution of tissue and/or tissue structures positioned near the sensor array to diagnose potentially life threatening diseases, for example a fibrous cap covering a vulnerable plaque. In specific embodiments, the sensors are attached to an expandable member, for example a balloon, which can be inflated to urge the probe sensors radially outward to position the sensors near the tissue structures.

Systems and methods deploy an electrode from a catheter assembly. The systems and methods provide a catheter handle having a trigger lever adapted to carry an actuator rod. The actuator rod is adapted to cause movement of the electrode between a retracted position and an extended position. A pinion is carried by the trigger lever for engagement with a rack carried by the actuator rod. Compression of the trigger lever moves the rack along the actuator rod between a first position corresponding to the electrodes being in the retracted position and a second position corresponding to either the primed electrode firing position or the electrodes being in an extended position.
摘要:
An ultrasonic processing method and apparatus (20) can include a rotatable, ultrasonic horn member (28) that is operatively joined to an isolation member (42) which has high rigidity. A rotatable anvil member (86) can be cooperatively positioned to provide a selected horn-anvil gap (106), and an automated drive (130) can be connected to an actuator (110), or other transfer device, to automatically adjust the horn-anvil gap (106). An electronic processor (128) can be configured to monitor an intermittent gap force detected from an output provided by a force sensor (126), and can provide a drive signal to the automated drive (130) to thereby adjust the horn-anvil gap (106) to operatively maintain a target, gap force value.
摘要:
A plastic floor mat and foot rest unit is disclosed in which a front edge of the support surface of the foot rest is inserted through a slotted opening in the floor mat to the underside of the floor mat, and a latching projection is also inserted through the opening to latch the front edge of the support surface in the opening, yet permit its ready removal if desired. The rear edge of the support surface is also supported by a support plate to permit the incline angle of the foot rest support surface to be adjusted and to support the rear edge by the pile of the carpet upon which the floor mat and foot rest unit is to be used.
