However, a challenge remains the definition of speckle and its correspondence in the image
For these reasons, existing "speckle decorrelation" methods are only successfully applied in fairly special cases, and may not be successful in all real-world situations

Embodiment Construction

[0019] Figure 1a The ultrasound probe 10 is shown moving along the volume 2 . Here, the volume part 2 is the body part of the patient. The movement of the probe is indicated by arrow 12, which represents the starting position ( Figure 1a Probe 10 shown on the left) to the final motion position ( Figure 1a The movement of the probe 10) is shown on the right. During motion, the probe 10 collects ultrasound image data representing successive ultrasound image frames. Each ultrasound image frame provides an ultrasound image (ie, the graph of ultrasound reflection properties may represent information) in a specific imaging region or image plane 22 , ie in a two-dimensional or three-dimensional subspace of the volume portion 2 . The imaging region 22 has a predetermined shape and position relative to the ultrasound probe 10 , and the imaging region moves together with the ultrasound probe 10 . By moving the ultrasound probe 10 the image area 22 is moved over the volume 2 such th...

Abstract

A method of determining a three-dimensional motion of a movable ultrasound probe (10) is described. The method is carried out during acquisition of an ultrasound image of a volume portion (2) by the ultrasound probe. The method comprises receiving a stream of ultrasound image data (20) from the ultrasound probe (10) while the ultrasound probe is moved along the volume portion (2); inputting at least a sub-set of the ultrasound image data (20, 40) representing a plurality of ultrasound image frames (22) into a machine-learning module (50), wherein the machine learning module (50) has been trained to determine the relative three-dimensional motion between ultrasound image frames (22); and determining, by the machine-learning module (50), a three-dimensional motion indicator (60) indicating the relative three-dimensional motion between the ultrasound image frames.

Description

[0001] Aspects of the present application generally relate to a method of determining three-dimensional motion of a movable ultrasound probe. The method is performed in particular during acquisition of an ultrasound image of the volume portion by the ultrasound probe. The method includes, inter alia, determining a three-dimensional motion index indicative of relative three-dimensional motion between ultrasound image frames. Aspects of the present application also relate to a corresponding device for determining a three-dimensional motion of an ultrasound probe. Background technique [0002] Ultrasound imaging (ultrasound) is one of the main medical modalities used for diagnostic and interventional applications due to its unique characteristics - affordability, availability, safety and real-time capabilities. However, for a long time, it has not been possible to acquire 3D images in a simple and reliable manner, and this limitation has reduced the scope of clinical application...
