Method for using a transrectal probe to mechanically image the prostate gland

摘要: New methods and devices for measuring geometrical mechanical parameters of body tissues providing imaging (MI) the based on these are described in applicant's parent U.S. patent application Ser. Nos. 08/607,645 07/994,109. In essence, a pressure sensing array is used to measure surface stress pattern soft tissues, changes as function applied pressure, position time processed construct an image internal structure tissues. The detected provide sensitive information useful detection diagnosis tissue pathologies such breast prostate tumors. accordance with present invention, data acquired by pressing transrectal probe overlying prostate. responses determined conveniently represented superposition Chebyshev polynomial functions. A three-dimensional model reconstructed using finite element analysis, formed deforming ideal conform calculated model. Regions irregularity can be indicated image.
