ABSTRACT:
To disintegrate a calculus present within a biological body under medical examination, the following steps are employed: irradiating ultrasonic pulses to an interior region of the biological body which contains at least the calculus; receiving echo pulses reflected from the interior region of the biological body to produce reflection signals; detecting both a maximum signal level and a minimum signal level from the reflection signals received during a predetermined time period; setting a first threshold value based on both of said maximum signal level and said minimum signal level; and, focusing a shock wave onto the calculus contained in the interior region of the biological body only while signal levels of the reflection signals exceed the first threshold value.
