Method of using frame of pixels to locate ROI in medical imaging

A method of locating a region of interest (ROI) within a patient from a plurality of parallel frames of two-dimensional intensity data, comprising:

• assembling at least one group of said plurality of parallel frames;
• generating a two dimensional projected frame of pixels of a specified characteristic intensity projection for the parallel frames of the group;
• determining third dimensional data for each pixel in the group, said third dimension comprising the depth of a frame having the specified characteristic for each pixel in the projected frame;
• and
• locating the ROI by selecting a pixel in the two-dimensional projected frame,
• wherein the specified characteristic is the maximal projected intensity, and the two-dimensional projected frame is a maximal intensity projected (MIP) frame, and including:
• storing the third dimensional data;
• locating a cursor on the selected pixel in the MIP suspected of indicating an ROI;
• clicking on the cursor located on the pixel in the MIP;
• fetching the two-dimensional data of the two dimensions and intensity from pixels in the vicinity of the cursor located in the MIP and the stored third dimensional data responsive to the click on the cursor;
• and
• generating images using the fetched data.

• and
• storing third dimensional data in the virtual frame at the two dimensions that locate the maximum intensity pixel of each of the pixels of the MIP frame.
