This invention relates to a pressure measurement apparatus for inspecting therapentic energy waves, e.g. shock waves or ultrasonic waves. The pressure measurement apparatus for inspecting focal position and pressure of therapeutic energy waves comprises a pressure sensing sheet which changes visually or electrically according to the pressure, and a marker for setting the focal position, mounted on the pressure sensing sheet. Also, the apparatus for inspecting focal position and pressure of therapeutic energy waves in a water tank, comprises, a pressure sensing sheet which changes visually or electrically according to the pressure, a mount for holding the pressure sensing sheet as a flat shape, a mount holder for holding the mount, a marker for setting the focal position, held above the pressure sensing sheet from the mount holder, and holder means for holding the mount holder into the water tank. It is an object of the present invention to provide a pressure measurement apparatus for inspecting therapeutic energy waves, e.g. shock waves and ultrasonic waves wherein the pressure of the energy waves is measured easily. It is another object of the present invention to provide a pressure measurement apparatus for inspecting therapeutic energy waves, wherein it is easy for the user to judge the focal position.

In a shock wave generating apparatus, a focal point marker is automatically made coincident with an image of an article to be disintegrated on a display screen. The shock wave generating apparatus includes: a shock wave generating source for producing a shock wave and transmitting the shock wave to a biological body under medical examination; an ultrasonic imaging unit including an ultrasonic probe to project an ultrasonic wave beam to the biological body, for producing and displaying an ultrasonic tomographic image of tissue within the biological body; a transporting unit for transporting both the shock wave generating source and ultrasonic probe along the biological body; a calculating unit for calculating a focal point of the shock wave generating from the source based upon a probe position signal derived from the ultrasonic probe, and for displaying the focal point within the tomographic image as the focal point marker; and, a transport controlling unit for detecting a positional condition of the ultrasonic probe to output a positional condition signal when an image of an article to be disintegrated located within the tissue of the biological body is displayed on the tomographic image, and for controlling the transporting unit so as to transport both the shock wave generating source and ultrasonic probe along a tomographic image coordinate system defined by the ultrasonic probe based upon the positional condition signal, whereby the focal point marker is continuously coincident with the image of the article to be disintegrated.

Shock wave generating apparatus capable of setting moving direction of

A shock wave treatment apparatus, in which a shock wave generator generates a shock wave toward a living body having an object to be disintegrated by the shock wave, and an ultrasonic wave probe transmits an ultrasonic wave toward the living body and receives an ultrasonic wave echo from the living body, in which a B-mode processor forms a B-mode section image from the ultrasonic wave echo, and a color flow mapping processor forms a color flow mapping image from the ultrasonic wave echo, and in which the B-mode section image and the color flow mapping image are displayed on a display. A processor for obtaining doppler information from the ultrasonic wave echo to reproduce doppler sounds from the doppler information may be also provided.

Shockwave treatment apparatus

In an acoustic wave therapy apparatus, a holder is provided with an irradiation device for generating acoustic waves for medical treatment, and a bag having a variable size and containing an acoustic wave propagation medium. The holder is also provided with a probe rod having at its one end an ultrasonic probe for ultrasonic tomographic imaging. The probe rod has at least one opening at its one end. A pipe is connected to the opening of the probe rod. The pipe is connected to fluid equipment for supplying and discharging the acoustic wave propagation medium into and from the bag member. The holder is held by a hand-type holding apparatus. A connector for connecting and disconnecting the pipe is arranged on a C-arm included in the hand-type holding apparatus.
