Semi-autonomous simulated brain Tumor Ablation with RAVENII Surgical Robot using behavior tree
Proceedings - IEEE International Conference on Robotics and Automation, 2015Co-Authors: Danying Hu, Yuanzheng Gong, Blake Hannaford, Eric J SeibelAbstract:Medical robots have been widely used to assist surgeons to carry out dexterous surgical tasks via various ways. Most of the tasks require surgeon’s operation directly or indirectly. Certain level of autonomy in robotic surgery could not only free the surgeon from some tedious repetitive tasks, but also utilize the advantages of robot: high dexterity and accuracy. This paper presents a semi-autonomous neurosurgical procedure of brain Tumor Ablation using RAVEN Surgical Robot and stereo visual feedback. By integrating with the behavior tree framework, the whole surgical task is modeled flexibly and intelligently as nodes and leaves of a behavior tree. This paper provides three contributions mainly: (1) describing the brain Tumor Ablation as an ideal candidate for autonomous robotic surgery, (2) modeling and implementing the semi-autonomous surgical task using behavior tree framework, and (3) designing an experimental simulated Ablation task for feasibility study and robot performance analysis.

CryoAblation versus radiofrequency Ablation for renal Tumor Ablation: time to reassess?
Journal of vascular and interventional radiology : JVIR, 2013Co-Authors: Debra A. GervaisAbstract:Of the widely available methods for renal Tumor Ablation, cryoAblation was the first to be assessed in the treatment of renal cell carcinoma (RCC) by using open surgical approaches. Open surgical access was necessary because early cryoprobes were too large for percutaneous application. Initial evaluation of percutaneous approaches to renal Tumor Ablation in humans included a “treat-and-resect” case reported by Zlotta et al (1) in 1997 and the first case with Ablation as the sole planned treatment reported by McGovern et al (2) in 1999. With the advent of percutaneous needle applicators, renal Tumor Ablation moved to interventional radiology suites with ultrasound (US), computed tomography, and, in some cases, magnetic resonance imaging guidance. With percutaneous cryoprobes available shortly thereafter, the next several years saw expansion of the use of percutaneous image-guided radiofrequency (RF) Ablation and cryoAblation of renal Tumors. Most recently, newer modalities such as microwave (MW) Ablation and irreversible electroporation (IRE) have been assessed, and even promoted by some, to treat small Tumors. The appeal of percutaneous needle applicators for Tumor Ablation was the avoidance of surgery in selected patients. Indications for renal Tumor Ablation include advanced age, multiple comorbid conditions, solitary kidneys, familial syndromes, or multiple sporadic RCC. Early experience with small Tumors showed a high technical effectiveness rate with a low recurrence rate over short follow-up intervals (3–5). These early successes led to growing enthusiasm for its use in growing numbers of patients, as documented by a Surveillance, Epidemiology, and End Results database trend evaluation comparing the

Preexisting chronic kidney disease and renal Tumor Ablation: preliminary answers and persistent questions.
Journal of vascular and interventional radiology : JVIR, 2012Co-Authors: Debra A. GervaisAbstract:t t a t o t A W s a t c This article by Wehrenberg-Klee et al (1) is a timely and well-written study addressing a critical clinical question in the field of renal Tumor Ablation. In the United States alone, more than 10% of people— or more than 20 million people—ages 20 years or older have chronic kidney disease (CKD) (2). Among patients 65 years of age and older, the prevalence of CKD exceeds 40% (1). With this background prevalence of CKD, the question of impact of renal Tumor Ablation on renal function in patients with CKD is a question that is likely to face almost any interventional radiologist who offers renal Tumor Ablation. CKD is a marker of increased mortality risk and a precursor to end-stage renal disease with its attendant costs (1). or these reasons, CKD has received increased attention from hysicians, governmental agencies, and other organizations 1). Any therapy, new or old, that risks a decrease in renal unction is subject to close scrutiny and intense evaluation of his risk versus benefit. During the past 13 years that my team has been erforming renal Ablation, I have seen the reporting of erum creatinine levels change from a single digit to a econd digit after the decimal point. Whether a change in hat second postdecimal digit after a renal Tumor Ablation as any clinical meaning is a question I have not anwered scientifically, although I have strongly reassured ervous house staff that I do not believe there is any eason to worry about the acute increase in the second

image guided Tumor Ablation standardization of terminology and reporting criteria
Radiology, 2005Co-Authors: Nahum S Goldberg, Debra A. Gervais, William J Charboneau, Gerald D Dodd, Damia E Dupuy, Cleme J Grassi, Joh F Cardella, Alice Gillams, Robe A Kane, Fred T. LeeAbstract:The field of interventional oncology with use of image-guided Tumor Ablation requires standardization of terminology and reporting criteria to facilitate effective communication of ideas and appropriate comparison between treatments that use different technologies, such as chemical (ethanol or acetic acid) Ablation, and thermal therapies, such as radiofrequency, laser, microwave, ultrasound, and cryoAblation. This document provides a framework that will hopefully facilitate the clearest communication between investigators and will provide the greatest flexibility in comparison between the many new, exciting, and emerging technologies. An appropriate vehicle for reporting the various aspects of image-guided Ablation therapy, including classification of therapies and procedure terms, appropriate descriptors of imaging guidance, and terminology to define imaging and pathologic findings, are outlined. Methods for standardizing the reporting of follow-up findings and complications and other important aspects t...

Tumor Ablation in the Kidney
Tumor Ablation, 2005Co-Authors: Debra A. Gervais, Peter R. MuellerAbstract:The interventional radiologist who establishes a percutaneous Tumor Ablation program will likely become skilled in liver Tumor Ablation before attempting to treat renal cell carcinoma. Liver Tumors are more common than primary renal Tumors, and most patients with liver Tumors are not surgical candidates. Thus, a steady influx of patients eligible for percutaneous Ablation of hepatic Tumors can be expected in many centers. In contrast, surgical removal remains the standard therapy for small renal cell carcinomas, and most patients can undergo resection (1). Nevertheless, with the incidence of renal cell carcinoma (RCC) increasing and with the aging population in the United States, the number of patients with small RCCs who are not good surgical candidates is expected to increase (2, 3, 4). Thus, from time to time, the radiologist experienced in percutaneous Tumor Ablation can expect to encounter patients for whom percutaneous treatment of RCC is the only option or the most reasonable one.

The role of radiologic imaging and biopsy in renal Tumor Ablation
World Journal of Urology, 2010Co-Authors: Omar Ortiz-alvarado, James Kyle AndersonAbstract:Purpose The rate of unintentionally discovered renal masses has been increasing along with a parallel increased incidence of renal cell carcinoma both in men and women. Ablation therapy has emerged as an alternative for the treatment of these small renal Tumors. Several techniques have been developed for renal Tumor Ablation with cryoAblation (CA) and radiofrequency Ablation (RFA) being among the most widely used and studied. The purpose of this article is to review the role of imaging and renal mass biopsy in renal Tumor Ablation with focus on CA and RFA. Methods We performed a PubMed^® database search from January 2000 to January 2010 using the terms: renal Tumor Ablation, renal biopsy, indications, imaging, computed tomography (CT) guided, magnetic resonance imaging (MRI) guided and ultrasound (US) guided. Conclusion Nephron-sparing procedures, such as cryoAblation and RFA, offer an adequate treatment option for selected patients. Imaging techniques such as ultrasonography, CT and MRI are critical to targeting thermal Ablation of renal masses. Intra-operative biopsy prior to treatment is becoming a standard procedure but controversy remains regarding pre-operative biopsy. Additionally, contradictory data exist on the value of post-Ablation biopsy.
