Translated from Byulleten’ Eksperimental’noi Biologii i Meditsiny, Vol. 169, No. 4, pp. 484-490, April, 2020 Original article submitted November 15, 2019 We analyzed the kinetic and kinematic variables of artificial tactile and artificial vibrotactile sensing test for mass detection in silicon phantom to determine tactile intensity and speed to obtain the best result in detecting the type and location of the mass. This study has utilized Artificial Tactile Sensing Instrument for Mass Detection (ATSIMD) in cylindrical silicone phantoms. The masses embedded in these samples were inserted in axial and environmental, deep and surface positions. The loading velocity, probe location, and the frequency of the applied force were considered as the independent variables in this study. It was found that for superficial mases the accuracy of detection at low speed 5 mm/sec, although dependent on the probe, but was 50% higher than under other conditions. For deep masses, with increasing mass depth, the accuracy of detection at medium speed of 8 mm/sec was 30% higher than at low speed. Mass detection by ATSIMD used in this study showed maximum efficiency at medium loading velocity. At low and high loading velocities, the dependence of mass detection on the probe location is related to the interaction of the testing method, tissue, and viscoelastic properties of the tissue. Key Words: prostate cancer detection; tactile sensing; silicone phantom; energy dissipation; residual displacement According to the U.S. Vital Statistics Center report in 2017, 22% of deaths were due to prostate cancer as the second leading cause of cancer deaths in men in the United States after lung cancer, so that out of every 41 men in the United States, one dies from prostate cancer [3,5,8]. Therefore, early detection of malignant tumors will significantly influence the duration of prostate cancer treatment. Artificial tactile sensing and its application in cancer detection have recently become widespread. Peng et al. [9] made a device based on artificial tactile sensing and by measuring the stiffness of different prostate tissues concluded that this method is capable of describing the stiffness of different tissues.
