Radiation exposure during orthodontic treatment: risk to children and adolescents

open access: yesActa Odontologica Scandinavica
Objectives: To estimate radiation risk to children and adolescents during orthodontic treatment by retrieving number and type of radiographs from the patient records. Material and methods: Radiographs, along with justifications for radiation exposure,

Lung Stereotactic Body Radiation Therapy (SBRT) dose gradient and PTV volume: a retrospective multi-center analysis

open access: yesRadiation Oncology, 2019
Background The treatment of lung lesions with stereotactic body radiation therapy calls for highly conformal dose, which is evaluated by a number of metrics. Lung stereotactic body radiation therapy clinical trials constrain a plans gradient index.

MRI-only based radiotherapy treatment planning for the rat brain on a Small Animal Radiation Research Platform (SARRP) [PDF]

open access: yes, 2015
Computed tomography (CT) is the standard imaging modality in radiation therapy treatment planning (RTP). However, magnetic resonance (MR) imaging provides superior soft tissue contrast, increasing the precision of target volume selection.

Impact of radiopacified bone cement on radiotherapy dose calculation

open access: yesPhysics and Imaging in Radiation Oncology, 2020
Background and purpose: Radiopacifiers are introduced to bone cements to provide the appearance of bone in kilovoltage (kV) radiographic images. For higher energy megavoltage (MV) radiotherapy treatment beams, however, these radiopacifiers do not cause a

Neuro-Dynamic Programming for Radiation Treatment Planning [PDF]

open access: yes, 2002
In many cases a radiotherapy treatment is delivered as a series of smaller dosages over a period of time. Currently, it is difficult to determine the actual dose that has been delivered at each stage, precluding the use of adaptive treatment plans ...

ACR Accreditation for Utah Valley Hospital’s Radiation Oncology Center

open access: yes, 2019
Becoming an accredited clinic through the American College of Radiology (ACR) and their Radiation Oncology Practice Accreditation (ROPA) program will provide third-party evaluation of patient care to ensure the best treatment possible for patients.

On Existence of $L^1$-solutions for Coupled Boltzmann Transport Equation and Radiation Therapy Treatment Optimization [PDF]

open access: yes, 2017
The paper considers a linear system of Boltzmann transport equations modelling the evolution of three species of particles, photons, electrons and positrons. The system is coupled because of the collision term (an integral operator).

Radio(chemo)therapy in locally advanced nonsmall cell lung cancer

open access: yesEuropean Respiratory Review, 2016
Definitive radiochemotherapy is the standard treatment for many patients with locally advanced nonsmall cell lung cancer (NSCLC). Treatment outcomes have improved over the last decades. Several treatment regimens have been shown effective and safe.
