A bit vector array apparatus provides a high speed method for processing network transmission controls. Complex data structures for controlling network access are represented in the simplest possible form as single bit vector elements. The bit vector elements are combined into bit vectors comprised of 32 single bit vector elements. The bit vectors are processed in parallel in the bit vector array apparatus, which is comprised of special-purpose bit manipulation functions to expedite the processing.

Method and apparatus for bit vector array

An ultrasound scanner may display volume renderings of objects in real time. In particular, the system can scan an object at a first time using the ultrasound scanner to provide a first 3D ultrasound dataset that represents the object and of an instrument at a first position. A volume rendering of at least a portion of the object and instrument can be displayed. The first position of the instrument can be adjusted relative to the object based on the displayed volume rendering to provide a second position of the instrument. The object is scanned at a second time using the ultrasound scanner to provide a second 3D ultrasound dataset that represents at least a portion of the object and the instrument at the second position.

Methods and systems for volume rendering using ultrasound data

A volumetric ultrasound system is used to determine the velocity of tissue using 3D echo data. In particular, the velocity of tissue in a 3D volume is determined by steering ultrasound beams to the tissue in the 3D volume and forming 3D echo data from receive ultrasound beams formed from reflections of the steered ultrasound beams from the tissue in the 3D volume. The velocity of the tissue associated with the 3D echo data can be determined using velocity determination techniques. The velocity of the tissue can be displayed in real-time. For example, in one embodiment, a sub-volume of the 3D volume can be scanned and the determined velocity of the tissue displayed in about 50 milliseconds (ms).
