Abstract
An ultrasonic diagnosis device includes an ultrasonic oscillator, contained in a probe which can be inserted into a blood vessel, which can vary direction of transmission and reception of ultrasonic waves to receive an echo signal from the wall of the blood vessel thereby calculating information about the inner and outer walls of a blood vessel and obtaining cross-sectional and three-dimensional images of a blood vessel and the like.
Claims54
An ultrasonic diagnosis device comprising:
- an ultrasonic probe having an insertable portion insertable into a blood vessel and incorporating an ultrasonic oscillator for transmitting and receiving an ultrasonic wave, said ultrasonic probe having an internal power source;
- a scanning means for rotatively and/or linearly scanning an emitting direction of said ultrasonic wave;
- a reception signal outputting means for outputting a reception signal corresponding to an ultrasonic echo signal which has been received by said ultrasonic oscillator after transmission of the ultrasonic wave from said ultrasonic oscillator;
- and
- a quantitative detecting means for determining, based upon said ultrasonic echo signal, at least one of a cross-sectional area of a blood vessel, a diameter of the blood vessel, a thickness of a blood vessel wall and pulsative changes thereof.
