    • A method for in-room computer reconstruction of a three-dimensional (3-D) coronary vascular tree from routine biplane angiograms acquired at arbitrary angles and without using calibration objects. The method includes seven major steps: (1) acquisition of two standard angiogram sequences by use of a single-plane or biplane imaging system, (2) identification of 2-D coronary vascular trees and feature extractions including bifurcation points, directional vectors, vessel centerlines, and construction of vessel hierarchy in the two images, (3) determination of transformation in terms of a rotation matrix R and a translation vector {right arrow over (t)} based on the extracted vessel bifurcation points and directional vectors, (4) establishment of vessel centerline correspondence, (5) calculation of the skeleton of 3-D coronary vascular trees, (6) rendering of 3-D coronary vascular tree with associated gantry angulation, and (7) calculation of optimal view(s) and 3-D QCA as quantitative measures associated with the selected vascular segment(s) of interest. The calculation of optimal views includes determination of 2-D projections of the reconstructed 3-D vascular tree so as to minimize foreshortening of a selected vascular segment, overlap of a selected vascular segment or both overlap and foreshortening of a selected arterial segment.

    • A method of, and apparatus for, determining properties relating to multi-phase systems are provided. In the method, an array of sample tubes each containing a sample of a multi-phase system is formed. An iterative process is used to generate at least two data sets of transmitted and/or backscattered values for each sample and the data sets for each sample are processed to determine at least one property of the sample. The apparatus has a support on which an array of sample tubes each containing a sample of a multi-phase system may be assembled. It also has a wave source and at least one wave detector for detecting transmitted and/or backscattered values for each sample and computer means for iteratively operating said wave source and said at least one detector to generate data sets of transmitted and/or backscattered values for each sample and for processing the data sets for each sample to determine at least one property of the sample.
