“…25 Images of the kidney can be used to translate a computed tomography-based preoperative surgical plan to an intraoperative environment. 26 Spine volumes have seen increasing use for procedures such as facet joint injection. 27 Ten healthy human participants (five male, five female, ages ranging from 21 to 26) were recruited.…”

Abstract. Volumes reconstructed from tracked planar ultrasound images often contain regions where no information was recorded. Existing interpolation methods introduce image artifacts and tend to be slow in filling large missing regions. Our goal was to develop a computationally efficient method that fills missing regions while adequately preserving image features. We use directional sticks to interpolate between pairs of known opposing voxels in nearby images. We tested our method on 30 volumetric ultrasound scans acquired from human subjects, and compared its performance to that of other published hole-filling methods. Reconstruction accuracy, fidelity, and time were improved compared with other methods.

“…Registry errors of 1.2 mm and target distances of 4.7 mm have been obtained by Mozer and coworkers. 30 In this work, the authors use a 3D/3D surface matching rigid registration between CT segmented structures and the 3D US images. Wein and colleagues 22 presented a fully automatic image-based algorithm for registering 3D freehand ultrasound sweeps with CT.…”

Background and Purpose: Precise needle puncture of the kidney is a challenging and essential step for successful percutaneous nephrolithotomy (PCNL). Many devices and surgical techniques have been developed to easily achieve suitable renal access. This article presents a critical review to address the methodologies and techniques for conducting kidney targeting and the puncture step during PCNL. Based on this study, research paths are also provided for PCNL procedure improvement. Methods: Most relevant works concerning PCNL puncture were identified by a search of Medline/PubMed, ISI Web of Science, and Scopus databases from 2007 to December 2012. Two authors independently reviewed the studies. Results: A total of 911 abstracts and 346 full-text articles were assessed and discussed; 52 were included in this review as a summary of the main contributions to kidney targeting and puncturing. Conclusions: Multiple paths and technologic advances have been proposed in the field of urology and minimally invasive surgery to improve PCNL puncture. The most relevant contributions, however, have been provided by the application of medical imaging guidance, new surgical tools, motion tracking systems, robotics, and image processing and computer graphics. Despite the multiple research paths for PCNL puncture guidance, no widely acceptable solution has yet been reached, and it remains an active and challenging research field. Future developments should focus on real-time methods, robust and accurate algorithms, and radiation free imaging techniques.

“…In 2004, Osorio et al presented augmented reality visualization that allowed projection of pre-operative CT onto the patient's body, although this system does not achieve real-time monitoring of the procedure (Osorio et al 2004). In 2005, Mozer et al evaluated the accuracy of the fusion of CT with real-time US for percutaneous renal access, reporting the encouraging registration accuracy of 4.7 mm between planned and reached targets (Mozer et al 2005). They noted that error was mainly due to needle deflection during puncture.…”
