Development of computer-based acoustic characterisation of medical phantom (IR)

The aim of this research is to develop a computerised measurement system for acoustic characterisation of medical phantom. The method used is the adaptation of insertion technique and the introduction of the stepped shape design of sample into the system. The developed system consists of an ultrason...
