Abstract (en)

[origin: WO9824065A1] There is disclosed a method and apparatus for reconstructing in 3D an image of an object scanned in 2D a plurality of times to produce a plurality of 2D image data slices at different angles of inclination. The slices are recorded and stored on a recording medium e.g. video tape, whereon the slices are recorded in succession together with at least one datum which identifies the image data slices as corresponding to at least one changing physical parameter such as positioning, ECG, and/or respiration cycle. The 2D image data slices are processed to create a 3D grid of points containing data values based on at least part of an object being scanned, with the image data values being inserted at the grid points as a result of processing the 2D image data slices in dependence upon said at least one datum. Preferably the scanning is carried out by feehand ultrasound scanning, and can be employed for the non-invasive determination of a condition inside a mammalian body.
