Dose tolerance limits and dose volume histogram evaluation for stereotactic body radiotherapy
Almost 20 years ago, Emami et al. presented a comprehensive set of dose tolerance limits for normal tissue organs to therapeutic radiation, which has proven essential to the field of radiation oncology. The paradigm of stereotactic body radiotherapy (SBRT) has dramatically different dosing schemes but, to date, there has still been no comprehensive set of SBRT normal organ dose tolerance limits...
متن کاملIs internal target volume accurate for dose evaluation in lung cancer stereotactic body radiotherapy?
PURPOSE 4DCT delineated internal target volume (ITV) was applied to determine the tumor motion and used as planning target in treatment planning in lung cancer stereotactic body radiotherapy (SBRT). This work is to study the accuracy of using ITV to predict the real target dose in lung cancer SBRT. MATERIALS AND METHODS Both for phantom and patient cases, the ITV and gross tumor volumes (GTVs...
متن کاملEvaluating proton stereotactic body radiotherapy to reduce chest wall dose in the treatment of lung cancer.
Stereotactic body radiotherapy (SBRT) can produce excellent local control of several types of solid tumor; however, toxicity to nearby critical structures is a concern. We found previously that in SBRT for lung cancer, the chest wall (CW) volume receiving 20, 30, or 40Gy (V20, V30, or V40) was linked with the development of neuropathy. Here we sought to determine whether the dosimetric advantag...
متن کاملSafety of high-dose-rate stereotactic body radiotherapy
BACKGROUND AND PURPOSE Flattening filter free (FFF) beams with high dose rate are increasingly used for stereotactic body radiotherapy (SBRT), because they substantially shorten beam-on time. The physical properties of these beams together with potentially unknown radiobiological effects might affect patient safety. Therefore here we analyzed the clinical outcome of our patients. MATERIAL AND...
متن کاملA dose-volume histogram based decision-support system for dosimetric comparison of radiotherapy treatment plans
BACKGROUND The choice of any radiotherapy treatment plan is usually made after the evaluation of a few preliminary isodose distributions obtained from different beam configurations. Despite considerable advances in planning techniques, such final decision remains a challenging task that would greatly benefit from efficient and reliable assessment tools. METHODS For any dosimetric plan conside...
