Design, Construction and Evaluation of an Anthropomorphic Head Phantom for Assessment of Image Distortion in Stereotactic Radiosurgery Planning Systems
Introduction: In recent years, the use of magnetic resonance (MR) images in radiation treatment planning has drawn considerable attention. However, although the extent of a tumor can be determined in great detail on MR images, the geometric accuracy of these images is limited by distortions stemming from the inhomogeneity of the static background magnetic field, the nonlineari...
متن کاملA virtual frame system for stereotactic radiosurgery planning.
PURPOSE We describe a computerized (or virtual) model of a stereotactic head frame to enable planning prior to the day of radiosurgery. The location of the virtual frame acts as a guide to frame placement on the day of the procedure. METHODS AND MATERIALS The software consists of a triangular mesh representation of the essential frame hardware that can be overlaid with any MR scan of the pati...
متن کاملStereotactic Radiosurgery/Radiotherapy: A Historical Review
"Stereotactic" is an exact radiotherapy treatment modality which implements invasive and non-invasive facilities for improving precise dose delivery. Stereotactic refers to three-dimensional localization of a specific point in space by a unique set of coordinates that relate to a fixed external reference frame. An accurate delivery of radiation is attainable using these techniques with high pre...
متن کاملStereotactic Radiosurgery for Sarcoma
The primary treatment of most sarcoma patients is surgery. The wider the excision, the lower the probability of local failure. For typical cases of non-CNS disease, adjuvant RT is offered in most cases in addition to surgery to optimize local control. However, bone and soft tissue sarcoma is historically considered a “radioresistant” tumor because conventionally fractionated radiation treatment...
متن کاملStereotactic Radiosurgery for Glioblastoma
Glioblastoma (GBM) is the most common primary malignant brain tumor in adults and one of the most aggressive of all human cancers. GBM tumors are highly infiltrative and relatively resistant to conventional therapies. Aggressive management of GBM using a combination of surgical resection, followed by fractionated radiotherapy and chemotherapy has been shown to improve overall survival; however,...
