“…The usual technique for 3D ultrasound calibration is to perform a series of scans of an object with known dimensions (a phantom) [13]. The simplest such object is a point fiducial formed by cross wires [4,10] or a small spherical ball [1,20] in a water bath. This point is scanned from different directions and segmented in each B-scan.…”

This paper presents improvements to the plane-based technique for calibrating freehand 3D ultrasound systems. The improvements are designed to make it easier for inexperienced users to perform plane-based calibration and to know that they have got a reliable result. In particular, we enable the calibration to be performed using water at room temperature while producing a result that is valid for average soft tissue, and we show how it is possible to provide feedback on the reliability of the calibration using a metric based on the curvature of the calibration criterion function. We present comprehensive results showing that these innovations improve the precision of the calibration and offer useful feedback to the user.

“…2) on a target point defined in the US image with a set of different orientations of the probe. For each orientation, the endeffector pose will be recorded once the point is positioned in the image in order to estimate the spatial calibration parameters of the US system by the use of the offline Detmer method [2]. The visual task consists in centering the points P 1 and P 2 on a target indicated in the image.…”

“…For example, in Ref. [2], a method is presented whereby the intersection point P * (see Fig. 1) of a fixed, crossed string phantom constituted by two converging straight lines D 1 and D 2 , immersed in water has to be positioned in the US image for different orientations of the US probe; in Ref.…”

“…In order to facilitate the spatial parameters calibration of the 3-D US system, we propose to develop a robotic task that consists of automatically positioning the US image plane on the intersection point of the crossed string phantom used by the Detmer calibration method [2], while moving the probe to different orientations. This task will be performed by controlling the 6 d.o.f.…”

Abstract-A new visual servoing technique based on two-dimensional (2-D) ultrasound (US) image is proposed in order to control the motion of an US probe held by a medical robot. In opposition to a standard camera which provides a projection of the three-dimensional (3-D) scene to a 2-D image, US information is strictly in the observation plane of the probe and consequently visual servoing techniques have to be adapted. In this paper the coupling between the US probe and a motionless crossed string phantom used for probe calibration is modeled. Then a robotic task is developed which consists of positioning the US image on the intersection point of the crossed string phantom while moving the probe to different orientations. The goal of this task is to optimize the procedure of spatial parameter calibration of 3-D US systems.

“…There are varieties of geometrical phantoms proposed in the literature mainly to facilitate the calibration procedure. Phantoms with sparse set of wires are proposed in [1,3]. In these procedures, intersection points of the wires are being imaged and are related to the known 3D position of the same point in the phantom.…”

Abstract. This paper introduces a novel method for ultrasound calibration for both spatial and temporal parameters. The main advantage of this method is that it does not require a phantom, which is usually expensive to fabricate. Furthermore, the method does not require extensive image processing. For spatial calibration, we solve an optimization problem established by a set of equations that relate the orientations of a line (i.e., calibration pointer) to the intersection points appearing in the ultrasound image. The line orientation is provided through calibration of both ends of the calibration pointer. Temporal calibration is achieved by processing of the captured pointer orientations and the corresponding image positions of intersection along with the timing information. The effectiveness of the unified method for both spatial and temporal calibration is apparent from the quality of the 3D reconstructions of a known object.
