US 2026/0283597 A1 · ASSESSING ACQUISITION QUALITY OF A 3D ULTRASOUND SCAN

Abstract

Proposed concepts aim to provide schemes, solutions, concepts, designs, methods and systems pertaining to assessing acquisition quality of a scan of a subject by a 3D ultrasound scanner. Specifically, assessment of image quality in 3D is achieved based on a coherence value of the image data generalized in an elevation dimension (rather than an azimuth dimension used for 2D ultrasound data). Thus, image quality values are determined for different parts of the 3D region based on the coherence factor of the associated ultrasound image data. From the image quality values, a volume of the 3D region that is adequately scanned may be determined. In this way, feedback regarding the acquisition quality of the 3D ultrasound scan may be provided.

Dependent claims

A method for assessing acquisition quality of a scan of a subject by a 3D ultrasound scanner, comprising:

obtaining ultrasound image data associated with a 3D region of a subject;
determining for each of a plurality of different parts of the 3D region, an image quality value indicating a quality of the ultrasound image data associated with the part of the 3D region, each image quality value based on a coherence factor of the associated ultrasound image data in an elevation dimension of the 3D region;
and
determining a volume of the 3D region that has a predetermined minimum acquisition quality based on identifying parts of the 3D region associated with image quality values meeting a predetermined requirement, wherein the predetermined requirement is based on at least one of:
a contrast value;
a resolution value;
a distortion value;
a noise value;
a sharpness value;
and an artifact density value.
