Interventional Radiology Virtual Simulator for Liver Biopsy and Nephrostomy
نویسنده
چکیده
We present here a new simulator for visceral needle puncture training in interventional radiology. This is the result of a close collaboration between different universities, involving computer scientists, clinicians and clinical engineers. Together, we address the need of segmentation, physically-based modelling, haptics rendering, pseudo-ultrasound generation and the conception of a mannequin required to build an efficient real-time simulator. Clinical face and content validations have also been performed and show the reliability and effectiveness of this framework.

متن کاملHaptic Simulation of the Liver with Respiratory Motion
During a standard procedure of liver biopsy, the motion due to respiration may be difficult to handle. The patient is often requested to hold his breath or to breathe shallowly. Ideally, this physiological behaviour should be taken into account in a virtual reality biopsy simulator. This paper presents a framework that accurately simulates respiratory motion, allowing for the fine tuning of rel...

First described in 1955 by Goodwin et al as a minimally invasive treatment for urinary obstruction causing marked hydronephrosis, percutaneous nephrostomy (PCN) placement quickly found use in a wide variety of clinical indications in both dilated and nondilated systems. Although the advancement of modern endourological techniques has led to a decline in the indications for primary nephrostomy p...

PURPOSE We aimed to evaluate the clinical superiority of using C-arm computed tomography (CT) to establish percutaneous nephrolithotripsy (PCNL) access for patients with non-dilated renal collecting systems. METHODS From May 2014 to May 2015, 33 patients underwent C-arm CT-guided puncture to establish PCNL access after failed attempts of ultrasonography-guided nephrostomy. Technical success, ...
