Problems solved by technology

[0002] A major problem in ultrasound object tracking systems is that the tracked object (e.g. the tip of a needle) moves across the image as it advances through the tissue (e.g. as the needle is pushed into the tissue)

Embodiment Construction

[0025] Embodiments of the invention relate to ultrasound object zoom tracking.

[0026] Advantageously, embodiments of the present invention can keep the tracked position of the object within the field of view, especially when the image is zoomed such that there is an option for panning. Furthermore, the present invention can position the translated image such that the tracked object is displaced from the center of the image so that the central portion of the image shows the tissue that the object will pass through as it physically advances through the tissue. These and other aspects of the invention are described herein.

[0027] In an embodiment, the invention automatically moves the field of view based on the position of the tracked object. The invention is particularly applicable when the system has zoomed in on the image via a video zoom function, which means that the scanned image data is available in both lateral and depth dimensions, but not on the screen. The automa...

Abstract

An ultrasound apparatus for imaging an anatomical region is provided. The ultrasound apparatus includes an ultrasound probe (288) having a medical instrument (202) in communication therewith, and an ultrasound sensor (279) mounted on the medical instrument. The ultrasound device further includes a hardware processor (214) configured to draw a region of interest (ROI) relative to a tip of the medical instrument on the ultrasound image displayed on the display device, and automatically and selectively performing ROI refinement by positioning a display portion of a scanned image such that the ROI is located in a preferred specific region of the display portion of the scanned image. The displayed portion of the scanned image is a selectively magnified region within the anatomical region including the medical instrument and spanned by an ultrasound scan line pattern.

Description

technical field [0001] The present disclosure relates to object detection, and more particularly to ultrasound object zoom tracking. Background technique [0002] A major problem in ultrasound object tracking systems is that the object being tracked (eg the tip of a needle) moves across the image as it advances through the tissue (eg as the needle is pushed into the tissue). In current systems (whether objects are being tracked or not), when video zooming is active (e.g., enabled via gestures using the user interface (UI)), especially if the zoom factor is high, the tiny pin or probe, whether intentional or not, Any movement may move the needle tip out of the area of ​​the displayed enlarged image. [0003] Thus, there is a need for zoom tracking of ultrasound objects that addresses these deficiencies. Contents of the invention [0004] According to an aspect of the invention, an ultrasound system for imaging an anatomical region is provided. The ultrasound system inclu...
