    摘要: Methods and systems are presented that improve a radiologist's ability to identify polyps by automatically and more accurately detecting and displaying colonic residue such as tagged or untagged stool or colonic fluid in medical images of the colorectal region. A virtual colonography imaging system obtains medical imagery of the colon. Improved computer-aided detection (CAD) algorithms identify colonic residue in the imagery by calculating feature vectors of and using statistical classification methods to classify regions of colonic residue to distinguish them from false positives.

    摘要: A driver for a series-coupled white LED string is provided. The driver includes a boost converter that is arranged to provide an output voltage from a source voltage. Also, the driver includes one switch that is coupled across half of the series-coupled LEDs, and another switch that is coupled across the other half of the series-coupled LEDs. A 50% duty cycle signal is employed to control the switches. While the boost converter is enabled, one of the switches is on and the other is off.

    摘要: A system and method for preserving CAD marks falling outside the three-dimensional rendering on a visualization display following segmentation of CT medical image slices for review by a user is disclosed. The CT medical images are processed by both a CAD algorithm and a visualization workstation. The CAD algorithm reports detected suspicious regions to the visualization workstation for display on the three-dimensional rendering of the medical images as well as creates a list of the detections to notify the user. If the detected CAD marks are not located on the three-dimensional rendering of the medical images, the user is notified. The user can the view the detected CAD marks on the two-dimensional CT medical images.
