    • The present invention relates to an ultrasound-image-guided system and to a volume-motion-based calibration method for operating such system. The system comprises one or more ultrasound probes (20) operable to generate image volumes (13i, 13j) of an anatomical object (10). The system further comprises an adapter device (50)comprising at least one position sensor (30), the adapter device (50) being, for one use event, attachable to one of the ultrasound probes (20). The at least one position sensor (30) is at a variable position with respect to the one or more ultrasound probes (20) from one use event to another use event. The system further comprises a tracking device (51) operable to generate tracking data (32) representative of a tracking of the at least one position sensor (30) within a coordinate system(11), and ultrasound imaging device (21) operable to generate imaging data (22) of the anatomical object (10) based on the image volumes (13i, 13j). The system further comprises a computation device (40) operable to automatically self-calibrate, for each use event, the imaging data (22) with respect to the coordinate system (11) of the at least one position sensor (30) by calculating a calibration matrix (51) using an image based volume motion (VM IB ) and a tracking based volume motion (VM TB ). The image based volume motion (VM IB ) representing an image motion of at least two image volumes (13i, 13j) derived from the imaging data (22). The tracking based volume motion (VM TB ) representing a tracking motion of the image volumes (13i, 13j) derived from the tracking data (32).

    • The present invention relates to a cable conduit section (10) comprising a base section (12) and a walkway section (14). The base section (12) has first and second side walls (22, 32) that define a channel section (16) having an open upper face which is arranged for accommodating a cable. The walkway section (14) is removably disposed over the open upper face of the channel section (16) so as to restrict access to the interior of the channel section (16). A plurality of cable conduit sections (10) can be coupled together so as to form a cable conduit 1 in which the channel sections provide a continuous channel (2) and the walkway sections provide a continuous walkway (3).
