Abstract

OBJECTIVE: Three- and four-dimensional transrectal ultrasound transducers are now available from most major ultrasound equipment manufacturers, but currently are incorporated into only one commercial prostate biopsy guidance system. Such transducers offer the benefits of rapid volumetric imaging, but can cause substantial measurement distortion in electromagnetic tracking sensors, which are commonly used to enable 3D navigation. In this paper, we describe the design, development and validation of a 3D-ultrasound-guided transrectal prostate biopsy system that employs high-accuracy optical tracking to localize the ultrasound probe and prostate targets in 3D physical space. METHODS: The accuracy of the system was validated by evaluating the targeted needle placement error after inserting a biopsy needle to sample planned targets in a phantom using standard 2D ultrasound guidance versus real-time 3D guidance provided by the new system. RESULTS: The overall mean needle-segment-to-target distance error was 3.6±4.0 mm and mean needle-to-target distance was 3.2±2.4 mm. CONCLUSION: a significant increase in needle placement accuracy was observed when using the 3D guidance system compared with visual targeting of invisible (virtual) lesions using a standard B-mode ultrasound guided biopsy technique.
