Abstract

An ultrasound imaging system (110) may include a transducer configured to transmit and receive ultrasound signals, a matching layer configured to have acoustic impedance between tissue to be imaged and a material of the transducer, a damping block configured to absorb ultrasound energy, and processing circuitry (316). The processing circuit (316) may acquire medical imaging data of an anatomical feature of the subject. The processing circuit (316) may determine a position of the anatomical structure relative to an anatomical feature of the subject. The processing circuit (316) may generate a four-dimensional (4D) model of the anatomical feature of the subject, the four-dimensional (4D) model including a visual indicator that identifies a location of the anatomical structure relative to the anatomical feature of the subject. The processing circuit (316) may display the 4D model via a user interface.

Description

System for enhancing 3D segmentation understanding by dynamic 4D anatomical landmarks Technical Field The present disclosure relates to a system for generating a four-dimensional (4D) model of an anatomical feature of a subject, the four-dimensional (4D) model including a visual indicator that identifies a location of an anatomical structure relative to the anatomical feature of the subject. Background A medical imaging system may acquire medical images of anatomical features in a region of interest of a subject. Furthermore, the medical imaging system may segment anatomical features in the medical image and generate a model of the anatomical features. The medical imaging system may display a model of the anatomical feature via a user interface to allow a user to view and evaluate the anatomical feature and measure the accuracy of the segmentation. In some cases, users with little experience or limited understanding of anatomy may find interpreting a displayed model challenging. For example, a user may find it difficult to assess the location of various anatomical structures of an anatomical feature, and/or to assess the quality and accuracy of segmentation of an anatomical feature. In the case where the model displayed is a 4D model, this problem may be exacerbated because the model may move over time.
