With the emergence of swept-volume ultrasound (US) probes, precise and almostreal-time US volume imaging has become available. This offers many newopportunities for computer guided diagnosis and therapy, 3-D images containingsignificantly more information than 2-D slices. However, computer guidanceoften requires knowledge about the exact position of US voxels relative to atracking reference, which can only be achieved through probe calibration. Inthis paper we present a 3-D US probe calibration system based on a membranephantom. The calibration matrix is retrieved by detection of a membrane planein a dozen of US acquisitions of the phantom. Plane detection is robustlyperformed with the 2-D Hough transformation. The feature extraction process isfully automated, calibration requires about 20 minutes and the calibrationsystem can be used in a clinical context. The precision of the system wasevaluated to a root mean square (RMS) distance error of 1.15mm and to an RMSangular error of 0.61 degrees. The point reconstruction accuracy was evaluatedto 0.9mm and the angular reconstruction accuracy to 1.79 degrees.
