3D dose reconstruction in external beam radiotherapy using portal imaging
The verification of the dose delivered to a patient during radiation therapy is a particularly important step for ensuring treatment quality. This step, known as in vivo dosimetry can be realized using a bidimensional dosimeter named Electronic Portal Imaging Device (EPID). However, few methods enable the determination of an accurate and fully personalized 3D dose distribution for the most curr...
متن کاملInvestigation of the dose enhancement effect of spherical bismuth oxide nanoparticles in external beam radiotherapy
Introduction: External radiotherapy is the most common method of radiotherapy which the most important problem associated with is that there is no difference between healthy and tumor tissues in dose absorption. One way to differentiate the dose sensitivity is to use metal-based nanoparticles. Bismuth oxide nanoparticles are good candidates for cancer radiotherapy. In this study, we investigate...
متن کاملThe Effect of Breast Reconstruction Prosthesis on Photon Dose Distribution in Breast Cancer Radiotherapy
Introduction: Siliconeprosthetic implants are commonlyutilizedfor tissue replacement and breast augmentation after mastectomy. On the other hand, some patients require adjuvant radiotherapy in order to preventlocal-regional recurrence and increment ofthe overall survival. In case of recurrence, the radiation oncologist might have to irradiate the prosthesis.The aim of this study was to evaluate...
متن کاملExternal beam radiotherapy with dose escalation in 1080 prostate cancer patients: definitive outcome and dose impact.
BACKGROUND The aim of this paper was to report definitive outcome of prostate cancer patients treated with dose escalation during a period of 12.5 years. METHODS From October 1999 to March 2012 we treated 1080 patients affected by prostate cancer, using External Beam Radiotherapy (EBRT). The mean age was 69.2 years. Most of the patients (69%) were staged as cT2, Gleason Score (GS)<7; the mean...
متن کاملDefining a dose-response relationship for prostate external beam radiotherapy.
INTRODUCTION We aimed to quantify a relationship between radiotherapy dose and freedom from biochemical failure (FFBF) in low- and intermediate-risk prostate cancer. To reduce confounding we used data with a standardised end-point, mature follow-up, low competing risk of metastatic failure, conventional fractionation and separate reporting for outcomes with hormonal therapy (HT). METHODS A sy...
