Title:
LUMEN MORPHOLOGY AND VASCULAR RESISTANCE MEASUREMENTS DATA COLLECTION SYSTEMS, APPARATUS AND METHODS
Document Type and Number:
WIPO Patent Application WO/2011/038044
Kind Code:
A3
Abstract:
A method and apparatus of automatically locating in an image of a blood vessel the lumen boundary at a position in the vessel and from that measuring the diameter of the vessel. From the diameter of the vessel and estimated blood flow rate, a number of clinically significant physiological parameters are then determined and various user displays of interest generated. One use of these images and parameters is to aid the clinician in the placement of a stent. The system, in one embodiment, uses these measurements to allow the clinician to simulate the placement of a stent and to determine the effect of the placement. In addition, from these patient parameters various patient treatments are then performed.
