Automated measurement and analysis of patient anatomy based on image recognition
First Claim
1. A method for measurement and analysis of patient anatomy with an ultrasound imaging system which generates an ultrasound image of a region of a patient and provides coordinates of walls of a vessel in the image, said ultrasound imaging system executing the steps of:
- a) in response to placement of a cursor within the vessel in the ultrasound image, automatically determining from the wall coordinates values of one or more parameters of the vessel in the vicinity of the cursor;
b) recording the determined parameter values; and
c) automatically moving the cursor to a plurality of positions along the vessel and repeating steps a) and b) at each of said plurality of positions, thereby automatically tracking the vessel.

Abstract
Methods and apparatus are provided for measurement and analysis of patient anatomy with an ultrasound imaging system which generates an ultrasound image of a region of a patient and provides coordinates of walls of vessels in the image. In response to placement of a cursor within the vessel in the ultrasound image, one or more parameters of the vessel in the vicinity of the cursor are determined automatically from the wall coordinates. The determined parameter values are recorded. The vessel parameters may include vessel diameter, vessel center coordinates and/or vessel wall directions. The vessel may be automatically mapped by moving the cursor to multiple positions along the vessel and determining the parameters of interest at each cursor position. The smallest vessel diameter may be determined and highlighted in the ultrasound image.

15. Apparatus for measurement and analysis of patient anatomy comprising:
-
an ultrasound imaging system for generating an ultrasound image of a region of a patient and for providing coordinates of walls of a vessel in the image; means responsive to placement of a cursor within the vessel in the ultrasound image for determining from the wall coordinates values of one or more parameters of the vessel in the vicinity of the cursor; means for recording the determined parameter values; and means for automatically moving the cursor to a plurality of positions along the vessel, determining values of said one or more parameters at each of said plurality of positions and recording the determined parameter values, thereby automatically tracking the vessel. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A method for measurement and analysis of patient anatomy with an ultrasound imaging system which generates an ultrasound image of a region of a patient and provides coordinates of walls of a vessel in the image, said ultrasound imaging system executing the steps of:
-
a) in response to placement of a cursor within the vessel in the ultrasound image, automatically determining vessel center coordinates in the vicinity of the cursor; b) automatically moving the cursor to the vessel center coordinates in the ultrasound image; c) automatically rotating the cursor into alignment with the vessel; d) automatically moving the cursor along the vessel in the cursor direction to a new position; e) automatically determining vessel center coordinates at the new position; and f) automatically repeating steps b) to e) to provide automatic tracking of the vessel center.
