Abstract: Tissue phantoms are, generally, used in the calibration of therapeutic and diagnostic systems. Thus, Tissue-Mimicking (TM) phantoms are developed and studied here for various ultrasonic output parameters. These phantoms have been developed by using agar-based Tissue-Mimicking Materials (TMM) with alumina as an absorption material. A pulser – receiver (make Panametrics, Model – 5800, Waltham, MA 02154, USA) has been used to measure ultrasonic velocity and attenuation coefficient, which were found to be 1540–1550 m/s and attenuation 10.0–35.0 dB/m-MHz at frequencies from 2.5 MHz to 5.0 MHz. These ultrasound test phantoms incorporating TM material are useful in the performance evaluation of medical ultrasound systems.

Keywords: tissue-mimicking phantom; ultrasound velocity; attenuation coefficient; healthcare systems; biomedical standards; tissue phantoms; ultrasound test phantoms; performance evaluation; medical ultrasound; biomedical technology.
