Abstract: The present disclosure provides a recovery device and a method for recovering a magnetic particle. The recovery device includes a main pipe, a needle tube, and a suction power mechanism. The needle tube is connected to a first end of the main pipe, and a terminal of the needle tube is magnetic for adsorbing a magnetic particle to the terminal of the needle tube. The suction power mechanism is configured to absorb the magnetic particle attached on the terminal of the needle tube into the main pipe. The present disclosure utilizes a magnetic needle tube to implement adsorption of the magnetic particle while the magnetic particle is absorbed into the main pipe by an absorption power mechanism, thus achieving recovering of the magnetic particle.

Abstract: An image processing method and system, a storage medium and a moving system are provided, and the image processing method includes: obtaining a 2D depth array Dp having depth information of a target object; calculating to obtain a depth vector D=[d1, d2, d3, . . . , di, . . . , dn], in which an element di is an average value of elements of the ith row in the 2D depth array; calculating to obtain an edge determination vector ?D=[?d1, ?d2, ?d3, . . . , ?di, . . . , ?dn?1], in which an element ?di=|di?di+1|; calculating an average value d0=(|?d2??d1|+|?d3??d2|+ . . . +|?dn?1??dn?2|)/(n?2); and comparing an absolute value |?di??di+1| with d0 to identify an edge of the target object, in which in a situation where |?di??di+1| is greater than d0, it is determined that the elements of the ith row in the 2D depth array Dp correspond to the edge of the target object.

Abstract: The present application relates to an ultrasound fusion imaging method and an ultrasound fusion image navigation system. The ultrasound fusion imaging method includes a selection step, a registration step and a fusion step. The selection step is for selecting at least one ultrasound image from at least one previously stored piece of ultrasound video data according to an input instruction. The ultrasound video data includes an ultrasound image obtained by acquiring a target object in at least one plane and position indicating information corresponding to the ultrasound image. The registration step is for registering the selected at least one ultrasound image with a modality image. The registration process uses the location of the position indicating information of the at least one ultrasound image. The fusion step is for fusing the registered ultrasound image with the modality image.

Abstract: An exemplary system includes a navigation system, an imaging system, and a data acquisition and analysis system. The exemplary system provides actively guidance for ultrasound image acquisition based on position information provided by the navigation system at different times (e.g., before and after an interventional procedure), to ensure that image data is collected at the same location within the object of interest (e.g., a target region of the interventional procedure) using the same probe posture (e.g., location and/or orientation).
