Publication number: 20140052027Abstract: The present invention relates to a method for real time mechanical imaging of a prostate with a transrectal probe. In the method, generating a composite two- and three-dimensional prostate mechanical image from a plurality of partial mechanical images extracted from pressure response data and a probe orientation data starts with examining the prostate by pressing a probe head pressure sensor array against it at various overlapping locations. Merging of partial mechanical images together is accomplished by analyzing an overlap between each subsequent and previous partial mechanical image. Finding the prostate is assisted with a supplemental pressure response data indicating the location of a sphincter known to be about 4-5 cm away from the prostate. Data processing is improved by including probe orientation data to further increase the accuracy and sensitivity of the method.Type: ApplicationFiled: October 8, 2013Publication date: February 20, 2014Applicant: Artann Laboratories, Inc.Inventors: Armen P.

Publication number: 20120277632Abstract: The present invention relates to a transrectal probe and method for real time mechanical imaging of a prostate. The probe is equipped with dual-array pressure sensors—one on the probe head and another on the shaft of the probe spaced away from the head with an angular and linear offset forming an S-shaped transition between the shaft and the head of the probe. The addition of the shaft pressure sensor array together with orientation tracking sensors allows precise calculation of the current head position throughout the examination of the prostate. Display means are used to guide the user in the proper manipulation of the probe in order to reduce the forces on surrounding tissues and organs and to minimize patient's discomfort.Type: ApplicationFiled: June 20, 2012Publication date: November 1, 2012Applicant: ARTANN LABORATORIES, INC.Inventors: Armen P.

Patent number: 8142368Abstract: A novel method for soft tissue characterization includes obtaining a sequence of surface stress patterns as a function of an increasing compression force when a probe is pressed against the tissue over the location of the lesion of interest. A number of elasticity features are then calculated to characterize the tissue and the lesion located therein including strain hardening, loading curve average slope, lesion peak signal under a predetermined load, tissue heterogeneity, lesion shape and lesion mobility. At least three elasticity features are provided as an input to a statistical Bayesian classifier trained on a clinical database to calculate the probability of the lesion being benign or malignant. Additional patient-related parameters may be further provided as inputs to the classifier to increase the accuracy of differentiation between benign and malignant lesions.Type: GrantFiled: October 2, 2008Date of Patent: March 27, 2012Assignee: Artann Laboratories Inc.Inventors: Vladimir Egorov, Armen P.

Patent number: 8069735Abstract: A tactile sensor array includes a first electrode layer and a second electrode layer with a two-phase compressible dielectric material therebetween. A ferroelectret film is used as a dielectric layer. In some embodiments, to improve sensor sensitivity and at the same time provide for high stability and reproducibility of sensor readings, the ferroelectret film is vented to atmosphere via a venting network of channels traversing at least one electrode layer and a curved rigid substrate.
