A patient with a severe kyphotic deformity presented for Stereotactic radiosurgery. In the supine position with the apex of the patient's kyphosis on the treatment couch, his head and buttocks were found to be approximately 30 cm from the table. Pretreatment consultation with the physicist and engineer was arranged. By creating a modified table mount for the head ring and a custommolded Styrofo...
PURPOSE To develop an accurate and efficient single-marker-based optical tracking system to enhance patient safety and quality of care in radiotherapy. METHODS The optical tracking system consists of a Polaris camera as well as in-house software. The camera is mounted inside the treatment room and detects the location of a single infra-red (IR) reflective marker affixed on patient skin in rea...
Introduction: Total body irradiation (TBI) is a form of external beam radiotherapy which is used in conjunction with chemotherapy with the purpose of immunosuppression. Since the target in TBI is the whole body so a uniform dose distribution throughout the entire body during TBI is necessary. As recommended by AAPM dose variation must be within ±10% of prescription dose. A revi...
The purpose of this study was to compare two clinical immobilization systems for intracranial frameless stereotactic radiosurgery (fSRS) under the same clinical procedure using cone-beam computed tomography (CBCT) for setup and video-based optical surface imaging (OSI) for initial head alignment and intrafractional motion monitoring. A previously established fSRS procedure was applied using two...
The optimal approach for magnetic resonance imaging-guided online adaptive radiotherapy is currently unknown and needs to consider patient on-couch time constraints. aim of this study was compare two different plan optimization approaches. comparison performed in 238 clinically applied online-adapted treatment plans from 55 patients, which the re-optimization selected based on physician's choic...
Craniospinal irradiation remains an important technique in the management of malignancies of the central nervous system. It is technically demanding, with potential for treatment field overlap or gaps to yield unacceptable dosimetric heterogeneity. A method to accurately simulate and verify the three-field junction is described. We use a comfortable supine position to minimize patient movement....
