Abstract:
An apparatus for performing an intravascular ultrasound imaging via an ultrasound signal transmitter and detector capable of being placed within a bodily lumen, comprising:an arrangement for detecting ultrasound signals;an arrangement for deriving a first image from a first set of detected ultrasound signals;an arrangement for processing and digitizing the first set of detected ultrasound signals;an arrangement for deriving a first two-dimensional array from the digitized first set of detected ultrasound signals, the first two-dimensional array including a first plurality of elements, wherein the first image is configured as the first two-dimensional array;an arrangement for deriving a second image from a second set of the detected ultrasound signals;an arrangement for processing and digitizing the second set of detected ultrasound signals;an arrangement for deriving a second two-dimensional array from the digitized second set of detected ultrasound signals, wherein the second image is configured as the second two-dimensional array, the second two-dimensional array including a second plurality of elements, each one of the first plurality of elements and the second plurality of elements representing a detected ultrasound signal from a predetermined spatial location; andan arrangement for performing a shift evaluation of the second image in relation to the first image in order to detect a motion.
