Three-dimensional ultrasonic diagnosis apparatus
First Claim
1. A three-dimensional ultrasonic diagnosis apparatus comprising:
- a transmitter/receiver configured to transmit ultrasonic beams three-dimensionally to a diagnostic site including a left ventricle of a heart in a subject being examined and configured to receive ultrasonic echo signals thereof;
a three-dimensional data generator configured to generate three-dimensional data of the diagnostic site based on the ultrasonic echo signals received by the transmitter/receiver;
a cardiac cavity region determining mechanism configured to determine a cardiac cavity region in the three-dimensional data generated by the three-dimensional data generator, and a display image generator configured to generate a display image so as to display blood flow information in a myocardial site of the heart discriminated from blood flow information in the cardiac cavity region by converting a value of the cardiac cavity region to a different value.

Abstract
A three-dimensional ultrasonic diagnosis apparatus has a feature that: transmits ultrasonic beams three-dimensionally to a diagnostic site including a left ventricle of the heart in a subject being examined; receives ultrasonic echo signals thereof; generates three-dimensional data of the diagnostic site based on the received ultrasonic echo signals; determines a cardiac cavity region in generated three-dimensional data; and generates a display image such that information at a myocardial site of the heart is identified by converting a value of the cardiac cavity region in the determined three-dimensional data to a different value. The feature enables the apparatus to provide information on three-dimensional myocardial muscle blood flow useful for clinical diagnosis.

15. A three-dimensional ultrasonic diagnosis apparatus comprising:
-
a transmitter/receiver configured to transmit ultrasonic beams three-dimensionally to a diagnostic site including a left ventricle of the heart in a subject being examined and configured to receive ultrasonic echo signals thereof;
a three-dimensional data generator configured to generate three-dimensional blood flow information data of the diagnostic site based on the ultrasonic echo signals received by the transmitter/receiver;
a region determining mechanism configured to determine a cardiac cavity region in the blood flow information data generated by the three-dimensional data generator; and
a display generator configured to generate a display image in which blood flow information in a cardiac cavity region is eliminated so as to display blood flow information in a myocardial site discriminated from blood flow information in the cardiac cavity region.

16. A three-dimensional ultrasonic diagnosis apparatus comprising:
-
a transmitter/receiver configured to transmit ultrasonic beams three-dimensionally to a diagnostic site including a left ventricle of a heart in a subject being examined and configured to receive ultrasonic echo signals thereof;
a three-dimensional data generator configured to generate three-dimensional blood flow information based on the ultrasonic echo signals received by the transmitter/receiver;
a display image generator configured to generate a display image so that a region with less blood flow information in a myocardial muscle of the heart is identified by changing an image processing method depending on a myocardial region and a cardiac cavity region of the heart so as to display blood flow information in a myocardial site discriminated from blood flow information in the cardiac cavity region; and
a display configured to display the display image generated by the display image generator.
