GUIDED ULTRASOUND IMAGING

The present disclosure describes imaging systems configured to generate volumetric images of a target feature based on anatomical landmarks identified during an ultrasound scan and in accordance with a user-selected view. Systems can include an ultrasound transducer configured to acquire echo signals responsive to ultrasound pulses transmitted toward a target region. A processor coupled with the transducer may present illustrative volumetric images of the target feature, each image corresponding to a particular view, for a user to select. The processor can then identify anatomical landmarks corresponding to the target feature embodied within 2D image frames, and based on the identified landmarks and user-selected view, provide instructions for manipulating the transducer to a target local to generate a 2D image frame specific to the view. Echo signals are then acquired at the target locale and used to generate an actual volumetric image of the target feature corresponding to the user-selected view.

Ultrasonic diagnostic apparatus and display method for ultrasonic inspection

A main image includes a tomographic image and a reference image as ultrasonic images. A sub-image includes a site-of-interest map and a site-of-interest list. During execution of ultrasonic inspection, each time a new site of interest is identified, a site-of-interest symbol is added to the site-of-interest map and a site-of-interest record is added to the site-of-interest list. The position of the site-of-interest symbol is determined according to the position of a probe mark.
