Monte Carlo dosimetry for and eye plaque brachytherapy

Medical Physics, 2008
A Monte Carlo study of dosimetry for eye plaque brachytherapy is performed. BrachyDose, an EGSnrc user code which makes use of Yegin's multi‐geometry package, is used to fully model (model 6711) and (model 200) brachytherapy seeds and the standardized plaques of the Collaborative Ocular Melanoma Study (COMS).

The Impacts of Episcleral Plaque Brachytherapy on Ocular Motility

Journal of Binocular Vision and Ocular Motility, 2021
Background: To investigate the effect of various factors on ocular motility disturbance after episcleral plaque brachytherapy with Ruthenium 106 (106Ru).Methods: Twenty consecutive patients who underwent plaque brachytherapy for all types of intraocular tumors were included in this interventional prospective case series.

Episcleral plaque brachytherapy for retinoblastoma

Pediatric Blood & Cancer, 2004
AbstractBackgroundThe purpose of this study was to report our experience using episcleral plaque brachytherapy (EPBRT) to treat retinoblastoma and to demonstrate its applicability in multimodality treatment.ProcedureWe treated 26 tumors in 25 eyes from a group of 21 children with unilateral (n = 4) or bilateral (n = 17) retinoblastoma.

Stereotactic radiotherapy as an alternative to plaque brachytherapy in retinoblastoma

Pediatric Blood & Cancer, 2010
Radioactive plaque brachytherapy has an established role for selected patients with retinoblastoma. Newer non-invasive radiotherapy techniques such as stereotactic conformal radiotherapy (SCR) that uses highly accurate positioning to deliver treatment with small beams may be an interesting alternative to brachytherapy. We report a case treated with SCR

Ruthenium-106 plaque brachytherapy for uveal melanoma

British Journal of Ophthalmology, 2015
To report on local tumour control, eye preservation and visual outcome after ruthenium-106 brachytherapy for uveal melanoma.Medical records of 143 eyes with uveal melanoma, treated by ruthenium-106 brachytherapy between 1997 and 2012 at one single centre, were included.

RADIATION DOSE TO THE SURGEON DURING PLAQUE BRACHYTHERAPY

Retina, 2012
To evaluate the radiation dose to a surgeon's hands during I eye plaque procedures.Sixteen consecutive patients with uveal melanomas were scheduled for eye plaque brachytherapy. The same surgeon wore thermoluminescent dosimeters on the dominant index finger and thumb while placing and removing the eye plaque to measure radiation dose.

Episcleral Plaque Brachytherapy

Seminars in Ophthalmology
Episcleral plaque brachytherapy is a treatment method for ocular tumors that involves placing radionuclide sources directly on or around the tumor using an episcleral plaque. This technique offers the advantage of a highly focused radiation dose, minimizing exposure to critical eye structures. Various radionuclides such as I-125, Ru-106, and Pd-103 are

β-Ray brachytherapy with 106Ru plaques for retinoblastoma

International Journal of Radiation Oncology*Biology*Physics, 2006
A retrospective analysis of 134 patients who received (106)Ru brachytherapy for retinoblastomas (175 tumors in 140 eyes). Treatment and follow-up were analyzed with special emphasis on tumor control organ, preservation, and late complications.Treated tumors had a mean height and diameter of 3.7+/-1.4 mm and 5.0+/-2.8 disk diameters, respectively.

Quantification of dose perturbation by plaque in vascular brachytherapy

European Journal of Clinical Investigation, 2005
AbstractBackground  Dose prescription and reporting in vascular brachytherapy (VBT) is based on the assumption that the vessel wall is water equivalent, which does not consider a possible dose perturbation by plaque. As the extent of this perturbation is unknown, we aimed to quantify dose attenuation by atherosclerotic plaque for beta‐ and gamma ...
