ULTRASONIC APPARATUS, AND PROGRAM FOR CONTROLLING THE SAME
First Claim
1. An ultrasonic apparatus comprising:
- an ultrasonic probe for performing transmission of ultrasonic push pulses to biological tissue in a subject to be examined, and transmission of ultrasonic detecting pulses for detecting shear waves generated by said push pulses in said biological tissue; and
a control circuit, wherein said control circuit executes;
a measurement-value calculating function of calculating a measurement value relating to elasticity of said biological tissue based on echo signals from said ultrasonic detecting pulses;
an index-value calculating function of calculating an index value indicating a degree of reliability of said measurement value for each of a plurality of factors that deteriorate the reliability of said measurement value based on the echo signals from the ultrasonic detecting pulses; and
a notifying function of notifying a factor corresponding to at least one index value for which said degree of reliability does not meet a required standard.

Abstract
[Problem] To provide an ultrasonic apparatus that enables one to find a factor that lowers reliability of a measurement value relating to elasticity of biological tissue.
[Means for Solution] An ultrasonic diagnostic apparatus comprises a control circuit executing: a measurement-value calculating function 535 of calculating a measurement value relating to elasticity of the biological tissue based on echo signals from ultrasonic detecting pulses; an index-value calculating function 536 of calculating an index value indicating a degree of reliability for the measurement value for each of a plurality of factors that deteriorate the reliability of the measurement value based on the echo signals from the ultrasonic detecting pulses; and a notifying function of notifying a factor corresponding to at least one index value for which the degree of reliability does not meet a required standard.

18. A program for controlling an ultrasonic apparatus, said apparatus comprising:
-
an ultrasonic probe for performing transmission of ultrasonic push pulses to biological tissue in a subject to be examined, and transmission of ultrasonic detecting pulses for detecting shear waves generated by said push pulses in said biological tissue; and a control circuit, wherein said program for controlling the ultrasonic apparatus causes said control circuit to execute; a measurement-value calculating function of calculating a measurement value relating to elasticity of said biological tissue based on echo signals from said ultrasonic detecting pulses; an index-value calculating function of calculating an index value indicating a degree of reliability of said measurement value for each of a plurality of factors that deteriorate the reliability of said measurement value based on the echo signals from the ultrasonic detecting pulses; and a notifying function of notifying a factor corresponding to at least one index value for which said degree of reliability does not meet a required standard.
