This paper presents a visual-servoing method that is based on 2-D ultrasound (US) images. The main goal is to guide a robot actuating a 2-D US probe in order to reach a desired cross-section image of an object of interest. The method we propose allows the control of both in-plane and out-of-plane probe motions. Its feedback visual features are combinations of moments extracted from the observed image...
This paper presents a new visual servoing method that is able to stabilize a moving area of soft tissue within an ultrasound B-mode imaging plane. The approach consists of moving the probe in order to minimize the relative position between a target imaging plane and the ultrasound plane observed by the probe of the moving tissue target. The problem is decoupled into motion out-of-plane and motion...
Robotized ultrasound examination offers on one hand more accuracy for the medical diagnostic and on the other hand a suitable assistance to radiologists. In the literature, very few researches deal with ultrasound image-based control of a medical robot holding the ultrasound probe. This paper presents a new visual servoing approach allowing the automatic guidance of the ultrasound probe. This technique...
Three-dimensional free-hand ultrasound imaging consists of capturing a set of ultrasound images with a 2D ultrasound system and their respective locations in order to position them in a 3D reference frame. Usually the clinician performs the acquisition manually through the use of an optical or magnetic localization system attached to the ultrasound probe. To assist the clinician, we propose to use...
