Title:
METHOD AND APPARATUS FOR SCREENING DIASTOLIC AND SYSTOLIC IMAGES BASED ON CARDIAC ULTRASOUND VIDEO
Document Type and Number:
WIPO Patent Application WO/2023/130662
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to a method and apparatus for screening diastolic and systolic images based on a cardiac ultrasound video. The method comprises: obtaining a cardiac ultrasound video; performing video image framing to generate a plurality of framed images; performing left ventricle semantic segmentation on each framed image to obtain a corresponding left ventricle segmented image; counting image areas to generate corresponding left ventricular area parameters; performing area-time curve conversion to generate a first area-time curve; performing significance threshold determination to generate a first significance threshold; recognizing significant peak and valley value points from existing peak and valley value points of the first area-time curve; screening effective peak and valley value points from the significant peak and valley value points; and taking framed images corresponding to the effective valley value points as end-systolic screening images, taking framed images corresponding to the effective peak value points as end-diastolic screening images, and sorting all the screening images to generate a screening image sequence. The stability of the image screening quality can be ensured by means of the present invention.
