Abstract: A method and system are provided for effecting interactive, three-dimensional renderings of selected body organs for purposes of medical observation and diagnosis. A series of CT images of the selected body organs are acquired. The series of CT images is stacked to form a three-dimensional volume file. To facilitate interactive three-dimensional rendering, the three-dimensional volume file may be subjected to an optional dataset reduction procedure to reduce pixel resolution and/or to divide the three-dimensional volume file into selected subvolumes. From a selected volume or subvolume, the image of a selected body organ is segmented or isolated. A wireframe model of the segmented organ image is then generated to enable interactive, three-dimensional rendering of the selected organ.

Abstract: A flashlight is provided with a conductive casing and a resilient sleeve positioned on the conductive casing. The sleeve is mounted on the casing by conducting a flow of pressurized gas through the casing, aligning the sleeve with the rear end of the casing to inflate the sleeve, and then urging the sleeve onto the casing. The sleeve is configured to expose the forward end of the casing, which is threaded to rotatably engage a head assembly. The head assembly includes a spring positioned therein for mounting a conductive rim of a lamp socket in abutment with the forward end of the casing.
