Image-guided neurosurgery using navigation systems is an essential tool to increase accuracy in brain tumor surgery. However, brain shift during surgery has remained problematic. The present study evaluated the utility of a new ultrasound (US)-linked navigation system for brain tumor surgery in 64 patients with intracranial tumors. The navigation system consisted of a StealthStation TM navigation system, a SonoNav TM system, and a standard US scanner. This system determines the orientation of the US images and reformats the images from preoperative computed tomography (CT) or magnetic resonance (MR) imaging to match the US images. The system was used intraoperatively to measure brain shift several times, using the results to guide tumor resection. US-linked navigation provided information regarding brain shift, and extent of tumor resection during surgery. Evaluation of brain shift was easily achieved in all patients, without using intraoperative CT or MR imaging. Accurate information regarding the true anatomical configuration of the patient could be obtained in all phases of the operation. Magnitude of brain shift increased progressively from pre-to post-resection and depended on the type of cranial structure. Integration of the US scanner with the navigation system allowed comparisons between the intraoperative US and preoperative images, thus improving interpretation of US images. The system also improved the rate of tumor resection by facilitating the detection of remnant tumor tissue. This US-linked navigation system provides information on brain shift, and improves the accuracy and utility of image-guided surgery.

“…Trobaugh et al (1994) and Meairs et al (2000) imaged a phantom with multiple point targets one at a time, but their theory is no different to the case when only a single target is used. The point phantom p is scanned, and its location p I = (u, v, 0) t segmented in the B-scan.…”

“…This phantom can be as simple as a point target. Indeed, this was one of the first phantoms (Detmer et al, 1994;State et al, 1994;Trobaugh et al, 1994) used for this purpose and continues to be used to this day (Barratt et al, 2006;Krupa, 2006). Calibrating with a point phantom can be divided into two classes, calibration with the aid of a stylus or without a stylus.…”

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 the mobile part of the position sensor. Numerous techniques for this have been developed over the past decade. In this review, we give a comprehensive description of existing calibration techniques and classify them according to the mathematical principles on which they are based. We give a thorough analysis of these approaches based on their accuracy, ease of use, reliability, and speed of calibration. To ensure consistency, these comparisons are done by the authors based on experimental results and not on figures quoted in previous papers.

“…Hitherto, techniques available for the compensation of brain deformation fell into 2 categories: intraoperative imaging (CT, MR imaging, or sonography) and NRR. [5][6][7][8][9][10][11][12][13][14][15][16][17][18] Among these, CT and sonography are not extensively applied on direct intraoperative imaging because of their low image resolution of soft tissue. Although intraoperative MR imaging [12][13][14][15][16][17][18] provides the best solution for brain deformation, it is not widely applied due to its high cost and long image-updating time.…”
