Abstract: The present invention proposes an apparatus and method for assisting a user to plan a puncture trajectory within a region-of-interest of a subject. The apparatus comprises: a data interface (211) configured to receive anatomical data of the region-of-interest of the subject and to output the at least one candidate puncture trajectory, and a data processor (213) for calculating at least one candidate puncture trajectory on basis of the anatomical data, multiple criteria, and a tradeoff among the multiple criteria. The anatomical data of the subject comprises three-dimensional data of the region of interest. The data processor (213) is further configured, upon receiving a first user input for adjusting the tradeoff among the multiple criteria, to adjust the tradeoff among the multiple criteria on basis of the first user input, and to calculate the at least one candidate puncture trajectory on basis of the anatomical data, the multiple criteria and the adjusted tradeoff among the multiple criteria. Different from conventional automatic planning tools which tend to offer a universal best tradeoff among multiple criteria for all cases, the proposed apparatus allows the user to tailor the tradeoff and thus tailor the automatic calculation of the candidate puncture trajectories so as to better meet the actual clinical needs.

Abstract: The invention relates to an apparatus for determining a relation between a surface motion of a body (BD) and an object motion of an object (OB) within the body (BD). The apparatus comprises a first sensing unit configured to acquire a first position signal indicative of a position of a first element placed at the location on the surface of the body with the surface motion; a second sensing unit configured to acquire a second position signal indicative of a position of a second element attached to an interventional device and placed on or in the object, wherein the first position signal and the second position signal are acquired during a given duration synchronously; and a third unit for calculating the relation between the surface motion and the object motion based on the first position signal and the second position signal. The invention also relates to a corresponding method for determining the motion relation.

Abstract: A method and an apparatus or needle visualization enhancement in ultrasound (US) imaging includes a Radon transform (RT) unit configured to perform RT on a sequence of frames to detect line features in the frames, where a frame includes US radio-frequency (RF) data obtained during monitoring the insertion of a needle into a subject or an US image reconstructed from the RF data. Further, a false needle feature removing unit is configured to remove line features which remain substantially stationary among the frames as false needles while locating a line feature which extends among the frames as the needle; and an overlaying unit is configured to overlay the location of the line feature as the needle on an US image of a frame to produce an enhanced image to be displayed.
