Development of Ultrasound Computed Tomography (USCT) transducer elements position calibration method was described. USCT experimental system having 1024 ring array transducer elements, diameter of 104mm, electronic High Voltage multiplexer circuits and commercially available ultrasound research platform was used. The result of applying the transducer elements position calibration to the received data, -6dB Tx/Rx beam width was 0.68mm for uncorrected, 0.20mm for corrected. Corrected value was almost same as simulated value. As a result, when reconstructing crosssectional images in the present experimental system, expected a precise image, not only reflection black-and-white images but also sound-of-speed transmission image would be reconstructed.
