This book was released on 2011 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: Stereotactic radiation therapy and stereotactic radiosurgery deliver radiation precisely to tumors, using special equipment to position and demobilize patients. The VisionRT system, with its component AlignRT, is a non-invasive stereotactic positioning and tracking system that uses cameras to capture infra-red images of patients, and process these images, to obtain precise shifts in patient location. This thesis evaluates the accuracy of the AlignRT system accuracy while setting up and tracking patients. Methods: This thesis investigates the setup accuracy of the AlignRT system based on the CT contour of an anthropomorphic phantom exported to the AlignRT from treatment planning systems, and compared results to those provided by the X-ray image-based positioning system ExacTrac. Measurements utilize a modified Winston-Lutz technique to derive the deviation of the planned isocenter relative to the radiation isocenter. A phantom embedded with a 16 mm metallic sphere and a Winston-Luts pointer were used as the positioning objects. A Varian electronic portal imaging device were utilized to obtain images. A Vidar scanner and RIT113v5.2 software were used to process images obtained in Winston-Lutz tests. Based on the equations derived for Winston-Lutz tests, shifts of the planned isocenter relative to the radiation isocenter were calculated, which were then used to judge the positioning the objects. Both positioning and tracking modes of AlignRT were tested. AlignRT, ExacTrac, and Winston-Lutz test measurements were all performed on the same Varian Novalis Tx system. Results: The results indicated that the AlignRT gave a positioning error of more than 1 mm based on CT contours and at small couch angles, which was larger than the clinical tolerance of 1mm for stereotactic radiation therapy. The positioning error would be less if the AlignRT system could be recalibrated with the same isocenter as the X-ray system or utilize its own initial image instead of CT contour. At larger couch angles, the positioning errors were larger than 1 mm even after recalibration. A further investigation and collaboration with the manufacture would be required to obtain desired accuracy.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The demand for high-precision radiotherapy (HPRT) was first implemented in stereotactic radiosurgery using a rigid, invasive stereotactic head frame. Fractionated stereotactic radiotherapy (SRT) with a frameless device was developed along a growing interest in sophisticated treatment with a tight margin and high-dose gradient. This dissertation establishes the complete management for HPRT in the process of frameless SRT, including image-guided localization, immobilization, and dose evaluation. The most ideal and precise positioning system can allow for ease of relocation, real-time patient movement assessment, high accuracy, and no additional dose in daily use. A new image-guided stereotactic positioning system (IGSPS), the Align RT3C 3D surface camera system (ART, VisionRT), which combines 3D surface images and uses a real-time tracking technique, was developed to ensure accurate positioning at the first place. The uncertainties of current optical tracking system, which causes patient discomfort due to additional bite plates using the dental impression technique and external markers, are found. The accuracy and feasibility of ART is validated by comparisons with the optical tracking and cone-beam computed tomography (CBCT) systems.

Download or read book Image guided Radiation Therapy written by Arno J. Mundt and published by PMPH-USA. This book was released on 2010-12-31 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Image Guided Radiation Therapy (IGRT) is a true revolution in the field of radiation oncology. IGRT provides the unprecedented means of conforming does to the shape of the target tissues in 3-dimensions reducing the risk of complications thereby improving the quality of life of irradiated patients. Moreover, IGRT provides the means to deliver higher than conventional doses thus improving the chance of cure in these patients. Despite its established benefits, several barriers exist to the widespread clinical implementation of IGRT. In the past, great concerns existed regarding the large capital outlay needed for both software and hardware. This barrier is less relevant today given the increased reimbursements possible with IGRT. Today, the most significant barrier is education. IGRT is a fundamentally new approach to both treatment planning and delivery. Adoption of the IGRT approach entails new ways of thinking in regard to patient selection, treatment planning and quality assurance measures. Unfortunately, apart from a few University-based short courses, limited resources are available for the physician and physicist interested in learning IGRT.
