The effects of radiation retinopathy on the retinal vasculature have been well established; however, the literature describing the pathologic changes in the choriocapillaris is relatively lacking. In this report, we describe the histologic findings o

Purpose The objective of this study was to examine feasibility of single- or hypo-fraction of high-dose-rate (HDR) electronic brachytherapy (eBT) in uveal melanoma treatment. Material and methods Biologically effective doses (BED) of organs at risk (

Purpose The number of studies that evaluate treatment margins for high grade gliomas (HGG) are limited. We hypothesize that patients with HGG who are treated with a gross tumor volume (GTV) to planning tumor volume (PTV) expansion of ≤1 cm will hav

Purpose To determine if the gamma knife icon (GKI) can provide superior stereotactic radiotherapy (SRT) dose distributions for appropriately selected meningioma and post‐resection brain tumor bed treatments to volumetric modulated arc therapy (VMAT

Objective Skull base chordomas (SBC) are characterized by persistent progression. Conventional radiation following resection increases 5- and 10-year local control (LC) to 36 and 23 %, respectively. Patients treated with protons result in 10-year LC

Imagingdose from megavoltage cone beam computed tomography (MVCBCT) can be significantly reduced without loss of image quality by using an imaging beam line (IBL), with no flattening filter and a carbon, rather than tungsten, electron target. The IBL

Traditional quality assurance checks of a patient's radiation therapy plan involve printing out treatment parameters from the treatment planning system and the “record and verify” (R&V) system and visually checking the information for one‐to‐

Stereotactic radiosurgery and image-guided radiotherapy (IGRT) place enhanced demands on treatment delivery machines. In this study, we describe a high-dose-rate output accelerator as a part of our stereotactic IGRT delivery system. The linac is a Si

Purpose: To test the radiobiological impact of hypofractionated choroidal melanoma brachytherapy, we calculated single fraction equivalent doses (SFED) of the tumor that equivalent to 85 Gy of I125-BT for 20 patients. Corresponding organs-at-risks (O
