In vivo dosimetry in external beam radiotherapy.
TLDR
The rationale for in vivo measurements is to provide an accurate and independent verification of the overall treatment procedure and enable the identification of potential errors in dose calculation, data transfer, dose delivery, patient setup, and changes in patient anatomy.
Retroperitoneal soft tissue sarcoma: an analysis of radiation and surgical treatment.
In vivo dosimetry in brachytherapy.
TLDR
Improvements within BT safety by developments of IVD into an effective method of independent treatment verification are encouraged by the Vision 20/20 paper.
Focal Radiation Therapy Dose Escalation Improves Overall Survival in Locally Advanced Pancreatic Cancer Patients Receiving Induction Chemotherapy and Consolidative Chemoradiation.
A comparative study of small field total scatter factors and dose profiles using plastic scintillation detectors and other stereotactic dosimeters: the case of the CyberKnife.
TLDR
Plastic scintillation detectors are strong candidates to become reference radiosurgery detectors for beam characterization and quality assurance measurements, whereas PSDs can be used to accurately measure total scatter factors and dose profiles on a CyberKnife system.
Duodenal toxicity after fractionated chemoradiation for unresectable pancreatic cancer.
Spectral method for the correction of the Cerenkov light effect in plastic scintillation detectors: a comparison study of calibration procedures and validation in Cerenkov light-dominated situations.
TLDR
The spectral method can be used to accurately correct the Cerenkov light effect in plastic scintillation detectors (PSDs) and two new procedures to determine the calibration factors of PSDs are proposed.
3D prompt gamma imaging for proton beam range verification.
TLDR
3D PG imaging for proton range verification under clinical beam delivery conditions is possible with a single Compton camera, and shifts in the proton beam range as small as 2 mm could be detected for delivery of a 2 Gy spot.
A phantom study of an in vivo dosimetry system using plastic scintillation detectors for real-time verification of 192Ir HDR brachytherapy.
TLDR
It is shown that the PSD system used in this study, which was capable of stem effect removal, can perform accurate dosimetry during 192Ir HDR brachytherapy treatment in a water phantom and has the potential for various online verifications of treatment delivery quality.
In vivo dosimetry: trends and prospects for brachytherapy.
TLDR
The capabilities of the state-of-the-art IVD technology in the context of error detection and quality assurance (QA) and the related prospects of the latest developments within the field are highlighted.
