Abstract

A system for automating biplane ultrasound imaging is provided. In one example, an ultrasound imaging system (100) includes a processing circuit (114) having a processor (116) coupled to a memory device (118) having instructions stored thereon that, when executed, cause the processing circuit (114) to perform operations. The operations include receiving a first image dataset obtained by an ultrasound probe (106) along two or more planes of a first orientation in a field of view, identifying at least one secondary anatomical feature based on the first image dataset, determining an additional plane oriented according to the at least one secondary anatomical feature in the field of view, automatically aligning a scan plane of the ultrasound probe (106) with the additional plane, receiving second image data obtained by the ultrasound probe (106) along the additional plane, and displaying a biplane image based on images from the first image dataset and the second image data.

Description

System for automated biplane ultrasound imaging Statement regarding federally sponsored research and development The present invention was completed with government support under grant No. 75a50123C00035 awarded by the Biomedical Advanced Research and Development Agency (BARDA). The government has certain rights in the invention. Technical Field Embodiments of the subject matter disclosed herein relate to ultrasound imaging, and more particularly, to automating biplane navigation of a probe during pulmonary ultrasound scanning. Background During a pulmonary ultrasound scan, an ultrasound probe is placed in a first orientation (e.g., a sagittal orientation toward the patient's head) by a technician, such as a sonographer. However, when a pathology is detected during an ultrasound scan, a technician may move the ultrasound probe from a first orientation to a second orientation (e.g., a lateral orientation). Ultrasound scanning is continued by collecting ultrasound data using the ultrasound probe in the second orientation. Images obtained during ultrasound scanning of the lungs depict anatomical features such as ribs, shadows of ribs, pleura (e.g., tissue covering the lungs), and the like. Disclosure of Invention Embodiments relate to an ultrasound imaging system. The ultrasound imaging system includes processing circuitry. The processing circuit includes a processor coupled to a memory device and the memory device has instructions stored thereon that, when executed, cause the processing circuit to perform operations including receiving a first image dataset obtained by an ultrasound probe along two or more planes of a first orientation in a field of view, identifying at least one secondary anatomical feature based on the first image dataset, determining an additional plane oriented according to the at least one secondary anatomical feature in the field of view, automatically aligning a scan plane of the ultrasound probe with the additional plane, receiving second image data obtained by the ultrasound probe along the additional plane, and displaying a biplane image on a display device of the ultrasound imaging system, the biplane image based on images from the first image dataset and the second image data.
