Abstract: A target biopsy system employing an ultrasound probe (20), a target biopsy needle (30) and a ultrasound guide controller (44). In operation, the ultrasound probe (20) projects an ultrasound plane intersecting an anatomical region (e.g. a liver). The target biopsy needle (30) include two or more ultrasound receivers (31) for sensing the ultrasound plane as the target biopsy needle (30) is inserted into the anatomical region. In response to the ultrasound receiver(s) (31) sensing the ultrasound plane, the ultrasound guide controller (44) predicts a biopsy trajectory of the target biopsy needle (30) within the anatomical region relative to the ultrasound plane. The prediction indicates the biopsy trajectory is either within the ultrasound plane (i.e., an in-plane biopsy trajectory) or outside of the ultrasound plane (i.e., an out-of-plane biopsy trajectory).

Abstract: The present invention provides a system and a method for imaging a volume of interest of a subject using ultrasound. The system comprises an ultrasound device adapted to acquire an image data set of the volume of interest of the subject and position information of a 3D ultrasound probe of the ultrasound device when the 3D ultrasound probe is placed at a position on the subject, the position information representing a position of the 3D ultrasound probe relative to at least three ultrasound sensors on an interventional device placed within the volume of interest, the at least three ultrasound sensors having predetermined relative positions at a distance from each other and not being aligned in a straight line; and an imaging device adapted to generate an image based on the image data set. According to the system, the position of the ultrasound probe may be derived in a convenient and low-cost manner.
