Peripheral dose distributions for a linear accelerator equipped with a secondary multileaf collimator and universal wedge
The American Association of Physicists in Medicine Task Group 36 (AAPM TG-36) data can be used to estimate peripheral dose (PD) distributions outside the primary radiation field. However, the report data does not apply to linear accelerators equipped with a multileaf collimator (MLC) and universal wedge (UW). Tertiary multileaf collimators have been shown to significantly affect PD distribution...
متن کاملImpact of the high-definition multileaf collimator on linear accelerator-based intracranial stereotactic radiosurgery.
OBJECTIVES The impact of two multileaf collimator (MLC) systems for linear accelerator-based intracranial stereotactic radiosurgery (SRS) was assessed. METHODS 68 lesions formed the basis of this study. 2.5 mm leaf width plans served as reference. Comparative plans, with identical planning parameters, were based on a 5 mm leaf width MLC system. Two collimation strategies, with collimation fix...
متن کاملA comparison of robotic arm versus gantry linear accelerator stereotactic body radiation therapy for prostate cancer
Prostate cancer is the most prevalent cancer diagnosed in men in the United States besides skin cancer. Stereotactic body radiation therapy (SBRT; 6-15 Gy per fraction, up to 45 minutes per fraction, delivered in five fractions or less, over the course of approximately 2 weeks) is emerging as a popular treatment option for prostate cancer. The American Society for Radiation Oncology now recogni...
متن کاملDosimetric performance of the new high‐definition multileaf collimator for intracranial stereotactic radiosurgery
The objective was to evaluate the performance of a high-definition multileaf collimator (MLC) of 2.5 mm leaf width (MLC2.5) and compare to standard 5 mm leaf width MLC (MLC5) for the treatment of intracranial lesions using dynamic conformal arcs (DCA) technique with a dedicated radiosurgery linear accelerator. Simulated cases of spherical targets were created to study solely the effect of targe...
متن کاملThe photon beam characteristics of linear accelerator equipped with additional narrow beam collimator
Stereotactic radiosurgery (SRS) using external beams of radiation has become an important method of treatment of small intracranial lesions such as arteriovenous malformations, benign or malignant primary tumours and isolated metastases. In this technique, a high dose of radiation is delivered to the stereotactically localized lesion, the adjacent normal brain tissue being minimaly irradiated.
