Robust and Automatic Calibration Method for 3D Freehand Ultrasound
This paper describes a new robust and fully automatic method for calibration of three-dimensional (3D) freehand ultrasound. 3D Freehand ultrasound consists in mounting a position sensor on a standard probe. The echographic B-scans can be localized in 3D, and can be compounded into a volume. However, especially for quantitative use, this process dramatically requires a calibration procedure that...
متن کاملA fully automatic calibration procedure for freehand 3D ultrasound
This paper describes a novel method for calibration of freehand three-dimensional (3D) ultrasound. A position sensor is mounted on a conventional ultrasound probe, thus the set of B-scans can be localized in 3D, and can be compounded into a volume. The calibration process aims at determining the transformation (translations, rotations, scaling) between the coordinates system of images and the c...
متن کاملCalibration Algorithm for Freehand Ultrasound
Ultrasound (US) image 3-D calibration for freehand probe is an extremely important technique in computerize 3-D ultrasonic (US image model reconstruction).Calibration is a procedure to calculate the spatial relationship between the US image and the tracker attached to the US probe. In this research, a different cross-string phantom and the corresponding algorithm are presented. The phantom with...
متن کاملFreehand Three-Dimensional Ultrasound Calibration
Freehand three-dimensional (3D) ultrasound is a technique for acquiring ultrasonic data of a 3D volume with application in radiotherapy and surgery planning. As the clinician sweeps the ultrasound probe over the anatomy, the trajectory of the probe is recorded using an attached position sensor. However, the position sensor tracks the position of the sensor, rather than the ultrasound B-scan. It...
متن کاملFreehand 3D Ultrasound Calibration: A Review
Freehand three-dimensional ultrasound is a technique for acquiring ultrasonic data of a 3D volume by recording the trajectory of the ultrasound probe using a position sensor. In planning and registration, a freehand ultrasound systems is used to track a two-dimensional probe. Probe calibration is necessary to find the rigid body transformation from the coordinate system of the B-scan to that of...
