The output given by the device should be used in combination with clinical and historical signs of melanoma to obtain additional information prior to a decision to biopsy.
Physical State Device is comprised of 1) Control Unit: processes examination data and presents electrical impedance spectra on the display, includes touch screen for user interaction, 2) Probe: holds the electrode used for lesion evaluation, 3)Probe Cable: connects probe to control unit, 3)Examination Electrodes – single patient use, sterile, disposable: The electrode head is covered with micro invasive pins (approximately 150 µm high with 170 µm triangular base), 4) Training Electrodes – single person use, sterile, disposable, 5) Test Impedance Tool, 6) Lesion Coverage Tool, 7) Power cord, 8)Battery, rechargeable (optional), and 9) USB flash drive
Technical Method It utilizes electric impedance to characterize skin tissue in real-time. It consists of a control unit and a disposable electrode.
