CyberKnife® M6™: Peripheral dose evaluation for brain treatments.

Physica Medica, 2015
This study evaluates the peripheral dose (PD) delivered to healthy tissues for brain stereotactic radiotherapy treatments (SRT) performed with a CyberKnife M6™ Robotic Radiosurgery System and proposes a model to estimate PD before treatment.PD was measured with thermoluminescent dosimeters.

Peripheral dose from megavolt beams.

Medical Physics, 1983
The peripheral dose (PD), defined as the dose outside of therapeutic radiation beams, has been investigated for 60Co, 4‐, 6‐, and 10‐MV x‐ray machines. The measurements have been carried out down to dose levels of about 0.1% of the peak dose in the beam, since that dose level may be of clinical importance in some situations. The PD measurements for the

Peripheral dose outside applicators in electron beams

Physics in Medicine and Biology, 2006
The peripheral dose outside the applicators in electron beams was studied using a Varian 21 EX linear accelerator. To measure the peripheral dose profiles and point doses for the applicator, a solid water phantom was used with calibrated Kodak TL films. Peak dose spot was observed in the 4 MeV beam outside the applicator.

Peripheral doses in CyberKnife radiosurgery.

Medical physics, 2006
The purpose of this work is to measure the dose outside the treatment field for conformal CyberKnife treatments, to compare the results to those obtained for similar treatments delivered with gamma knife or intensity-modulated radiation therapy (IMRT), and to investigate the sources of peripheral dose in CyberKnife radiosurgery.

Evaluation of MatriXX for IMRT and VMAT dose verifications in peripheral dose regions.

Medical Physics, 2010
PurposeMatriXX is a two‐dimensional ion chamber array designed for IMRT/VMAT (RapidArc, IMAT, etc.) dose verifications. Its dosimetric properties have been characterized for megavoltage beams in a number of studies; however, to the best of the authors’ knowledge, there is still a lack of an investigation into its performance in the peripheral or low ...

10-MV SBRT FFF IRRADIATION TECHNIQUE IS ASSOCIATED TO THE LOWEST PERIPHERAL DOSE: THE OUTCOME OF 142 TREATMENT PLANS FOR THE 10 MOST COMMON TUMOUR LOCATIONS.

Radiation Protection Dosimetry, 2019
There is a growing interest in the combined use of Stereotactic Body Radiation Therapy (SBRT) with Flattening Filter Free (FFF) due to the high local control rates and reduced treatment times, compared to conventionally fractionated treatments.

Nitrous oxide causes peripheral neuropathy in a dose dependent manner among recreational users

Journal of Psychopharmacology, 2020
Background: Nitrous oxide (N2O) has been used in clinical and recreational settings for over 150 years. Through inactivation of the Vitamin B12 dependent enzyme, methionine synthase, N2O can lead to the development of peripheral neuropathy.

Peripheral doses from pediatric IMRT

Medical Physics, 2006
Peripheral dose (PD) data exist for conventional fields and intensity‐modulated radiotherapy (IMRT) delivery to standard adult‐sized phantoms. Pediatric peripheral dose reports are limited to conventional therapy and are model based. Our goal was to ascertain whether data acquired from full phantom studies and/or pediatric models, with IMRT treatment ...

Peripheral Neuropathy and Low Dose Cisplatin

American Journal of Clinical Oncology, 1988
Five of 55 patients with metastatic carcinomas or unresectable primary carcinomas developed a peripheral neuropathy with "low dose" cisplatin therapy, consisting of 20 mg/m2 weekly. The neuropathy was primarily sensory, consisting of painful parasthesias and numbness in a "stocking glove" distribution.
