Abstract

The ultrasonic image diagnosis method is the one of the tests used to find diseases. The acoustic field characteristic analysis method is one of the ultrasonic probe's performance evaluations. In this paper, the quantitative acoustic field analysis method is suggested for quantitative probe evaluation. A medical ultrasonic probe which is decided abnormal in the development step, is evaluated by using the acoustic pressure distribution measurement system. The NFL (Near Field Length), emission angle, and area parameters are suggested for quantitative analysis. The statistica analysis gives that the range of parameter value of normal channel. The results of experiment shows the similar value of each parameters at normal channel.Sine the result of statistical analysis is very useful, the suggested parameters are will be able to estimate the ultrasonic probe
