ULTRASONIC DIAGNOSTIC APPARATUS AND MEDICAL IMAGE DIAGNOSTIC APPARATUS

1 . An ultrasonic diagnostic apparatus comprising:

processing circuitry configured to

acquire first positional information indicating a position of a puncture needle in a space from which an ultrasonic image is acquired and second positional information indicating a position of the puncture needle included in the ultrasonic image;

calculate a bend in the puncture needle based on the first positional information and the second positional information; and

correct a position of information indicating the puncture needle with respect to the ultrasonic image assumed based on the first positional information.

2 . The ultrasonic diagnostic apparatus according to claim 1 , wherein the processing circuitry is further configured to

display, on a display, information based on the corrected position of information indicating the puncture needle;

calculate a distance between a plurality of puncture needles the position of which is corrected; and

display the calculated distance.

3 . The ultrasonic diagnostic apparatus according to claim 2 , wherein the processing circuitry is configured to define a distal end of the puncture needle being operated as a viewpoint and define a direction of movement of the puncture needle as a line-of-sight direction and display, on the display, a display image obtained by arranging the puncture needle after operation and a region of interest on an image an up-and-down direction and a left-and-right direction of which are determined based on a section received from an ultrasonic probe.

4 . The ultrasonic diagnostic apparatus according to claim 1 , wherein the processing circuitry is configured to display, on a display, a three-dimensional image indicating a three-dimensional positional relation between a plurality of puncture needles and a region of interest.

5 . The ultrasonic diagnostic apparatus according to claim 1 , wherein the processing circuitry is further configured to output notification requesting correction when the corrected position of information indicating the puncture needle is changed.

6 . The ultrasonic diagnostic apparatus according to claim 1 , wherein the processing circuitry is further configured to

calculate an error between a puncture plan of the puncture needle and an insertion position of the puncture needle; and

output notification requesting correction of the position of the puncture needle when the calculated error exceeds a predetermined threshold.

7 . The ultrasonic diagnostic apparatus according to claim 2 , wherein the processing circuitry is configured to display, on the display, an output condition for treatment with the puncture needle based on the calculated distance between the puncture needles.

8 . The ultrasonic diagnostic apparatus according to claim 1 , wherein the processing circuitry is configured to calculate a curvature of a circle passing through the position indicated by the first positional information and the position indicated by the second positional information as the bend in the puncture needle.

9 . A medical image diagnostic apparatus comprising:

processing circuitry configured to

acquire first positional information indicating a position of a puncture needle in a space from which a medical image is acquired and second positional information indicating a position of the puncture needle included in the medical image;

calculate a bend in the puncture needle based on the first positional information and the second positional information; and

correct a position of information indicating the puncture needle with respect to the medical image assumed based on the first positional information.
