Ultrasonics. Real-time pulse-echo scanners. Phantom with cylindrical, artificial cysts in tissue-mimicking material and method for evaluation and periodic testing of 3D-distributions of void-detectability ratio (VDR)What is DD IEC TS 62558 Real time pulse echo scanners about? DD IEC TS 62558 is an international standard that covers the use of ultrasonics for various applications. DD IEC TS 62558 specifies the essential characteristics of a phantom and the method for the measurement of the void detectability ratio for medical ultrasound systems and related transducers. DD IEC TS 62558 is restricted to the aspect of long term reproducibility of testing results. DD
