Abstract (en)

[origin: WO0048515A2] There is disclosed a method for non-invasively determining dimensions of a lesion within soft tissue, comprising: (a) ultrasonically imaging soft tissue in an apparatus having an acoustic transducer, an acoustic focussing system, a holographic imaging detector, and a means for visualizing the holographic image; (b) obtaining a holographic planar image of a lesion in a first plane having a thickness z and having a dimension across a wide area of the lesion of x and a length across the lesion of y wherein y is at an approximately 90 degree angle to x; (c) determining if the image of the lesion is contained in different planar images; (d) measuring the x and y dimensions of the lesion in the plane having the largest sum of x plus y dimensions; and (e) determining the 3-dimensional size with a means for z-axis measurement.
