Development of computer-based acoustic characterisation of medical phantom
Anis Nazihah Mat Daud
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 ultrasonic pulser/receiver, two transducers, a digital oscilloscope, a thermometer and a computer. Special computer interfacing is used in the system software development. The resulted software display contains the connection and control panel, the display panel and the calculation panel. The block diagram for software algorithm contains the connection block, the signal acquisition display block, the analysis block and the help block. The performance of the system is tested on agar and poly(methyl methacrylate) (PMMA) samples for different positions from transmitter (0.00 to 90.00 mm), different shape of samples (rectangular and stepped shape of sample), different thicknesses of samples[(2.88 ± 0.0.....
