Rectal dosimetry in intracavitary applications of cervix carcinoma: Comparison of two methods [PDF]

Archive of Oncology, 2002
BACKGROUND: Brachytherapy of cervix carcinoma often results in high doses to surrounding structures, such as rectum and bladder. Therefore, these organs should be closely monitored.

A treatment planning study of combined carbon ion-beam plus photon intensity-modulated radiotherapy

Physics and Imaging in Radiation Oncology, 2020
Background and purpose: Combined photon intensity-modulated radiotherapy (IMRT) and sequential dose-escalated carbon ion beam therapy (IBT) is a technically advanced treatment option for head and neck malignancies. We proposed and evaluated an integrated

Impact of treatment planning target volumen (PTV) size on radiation induced diarrhoea following selenium supplementation in gynecologic radiation oncology - a subgroup analysis of a multicenter, phase III trial [PDF]

, 2013
Background: In a previous analysis (Int J Radiat Oncol Biol Phys 70:828-835,2010), we assessed whether an adjuvant supplementation with selenium (Se) improves Se status and reduces the radiation-induced side-effects of patients treated by adjuvant ...

A multi-centre analytical study of small field output factor calculations in radiotherapy

Physics and Imaging in Radiation Oncology, 2018
An audit methodology was developed and applied for output factor (OF) calculations in radiotherapy. The auditees were asked to calculate OFs for field sizes from 10 × 10 cm2 to 2 × 2 cm2.

Deep segmentation networks predict survival of non-small cell lung cancer [PDF]

, 2019
Non-small-cell lung cancer (NSCLC) represents approximately 80-85% of lung cancer diagnoses and is the leading cause of cancer-related death worldwide. Recent studies indicate that image-based radiomics features from positron emission tomography-computed
