[2] Introduction: Within an International Atomic Energy Agency (IAEA) co-ordinated research project (CRP), a remote end-to-end dosimetric quality audit for intensity modulated radiation therapy (IMRT)/ volumetric arc therapy (VMAT) was developed to verify the radiotherapy chain including imaging, treatment planning and dose delivery. [3] Infra-fraction motion of the prostate was recorded during 721 fractions of image guided radiotherapy (IGRT) in 28 patients, 14 of which were treated by intensity modulated radiation therapy (IMRT), and 14 of which were treated by volumetric arc therapy (VMAT). [4] RESULTS For EMBRACE-I, conformal radiation therapy (60% of patients) or intensity-modulated radiation therapy (IMRT) and volumetric arc therapy (VMAT; 40%) was applied with 45 to 50 Gy over 25 to 30 fractions to the elective clinical target volume (CTV).

The aim was to identify the PET radiopharmaceuticals best suited to the detection of cell hypoxia and to recognize the benefits for planning intensity-modulated radiation therapy (IMRT) and volumetric arc therapy (VMAT). [1] SBRT of multiple lung lesions synchronously (in one course) using a single-isocenter volumetric arc therapy (VMAT) plan with flattening filter free (FFF) beam or tomotherapy will shorten treatment courses, improve patient comfort by reducing treatment time, and improve clinic efficiency. [2] Aim:To investigate the potential clinical role of volumetric arc therapy on cervical cancer patients and its comparison with fixed-field Intensity-Modulated Radiotherapy (IMRT) was used as a benchmark. [3] For each patient, two plans were created using Volumetric Arc Therapy technique. [4] Eighty patients with head and neck cancers and undergoing volumetric arc therapy were taken up for the study. [5] CONCLUSION Our data demonstrated that UHRT administered with volumetric arc therapy (VMAT) can be recommended for selected patients with low-intermediate risk prostate cancer. [6] OBJECTIVES This multicentric study was carried out to investigate the impact of small field output factors (OFs) inaccuracies on the calculated dose in volumetric arc therapy (VMAT) radiosurgery brain plans. [7] Modern technologies such as the Active Breathing Coordinator (ABC) device, the AlignRT surface imaging system (by X X VisionRT), volumetric arc therapy (VMAT), and the automated planning (AP) module of the Pinnacle3 treatment planning system represent key tools to overcome several hurdles in this complex setting. [8] From 2018 to 2020, 80 patients with HNC underwent volumetric arc therapy (VMAT) to a dose of 66–70 Gy at 2 Gy per fraction with bilateral cochlea contoured for VMAT optimization as an organ at risk. [9] This study aims to calculate the costs of prostate cancer radiotherapy in a regional hospital Department of Radiation Oncology equipped with Three-Dimensional Conformal Radiation Therapy (3D-CRT) and Intensity Modulated Radiation Therapy (IMRT) Volumetric Arc Therapy (VMAT) radiation technology, using activity based costing (ABC), and to compare the costs of both methods at the level of component treatment process activities and with respect to insurance reimbursements. [10] This paper presents a dosimetric comparative study between VMAT and IMRT delivery based on current literature, while also presenting the potential challenges encountered with volumetric arc therapy. [11] Materials and methods Dynamic conformal arc (DCA ) and volumetric arc therapy (VMAT) plans were generated using 6 MV with a flattening filter (FF) and FFF beams. [12] We aim to critically examine the performance of the three-dimensional gammas vis-à-vis the older gamma metrics of lower dimensionality to determine their mutual fungibility in PSQA, using clinically approved Volumetric Arc Therapy (VMAT) plans. [13] All patients received whole gland prostate volumetric arc therapy (VMAT), 76 Gy in 38 fractions. [14] The purpose of this work is to establish an automated approach for a multiple isocenter volumetric arc therapy (VMAT)‐based TBI treatment planning approach. [15] TV and OARs were delineated on CT and MR, and volumetric arc therapy treatment plans were optimized independently (53. [16] The aim of this study was to compare the dosimetric parameters of Co-planar Intensity modulated radiotherapy (C-IMRT), non-coplanar (NC-IMRT), and volumetric arc therapy (VMAT) planning technique in hippocampal sparing (HS) whole brain radiotherapy (WBRT). [17] The purpose of this study is to examine if DIBH produces a clinically significant reduction in organ at risk (OAR) dose for right-sided WB + RNI, whilst comparatively analysing the use of volumetric arc therapy (VMAT) versus tangential inverse modulated radiotherapy (t-IMRT). [18] Materials and Methods We reviewed our institutional PBT registry and identified 17 patients with tumor epicenters within 2 cm of the eye and optic apparatus treated with passive scatter PBT with comparison volumetric arc therapy plans available. [19] Objective To compare volumetric arc therapy (VMAT) and helical tomotherapy (HT) plans in terms of dosimetric parameters in positron emission tomography- (PET-) computerized tomography- (CT-) based radiation therapy planning in unresectable malignant pleural mesothelioma (MPM). [20] Introduction: Within an International Atomic Energy Agency (IAEA) co-ordinated research project (CRP), a remote end-to-end dosimetric quality audit for intensity modulated radiation therapy (IMRT)/ volumetric arc therapy (VMAT) was developed to verify the radiotherapy chain including imaging, treatment planning and dose delivery. [21] Infra-fraction motion of the prostate was recorded during 721 fractions of image guided radiotherapy (IGRT) in 28 patients, 14 of which were treated by intensity modulated radiation therapy (IMRT), and 14 of which were treated by volumetric arc therapy (VMAT). [22] Group 1 was planned with volumetric arc therapy technique using coplanar arcs while Group 2—non-coplanar arcs. [23] RESULTS For EMBRACE-I, conformal radiation therapy (60% of patients) or intensity-modulated radiation therapy (IMRT) and volumetric arc therapy (VMAT; 40%) was applied with 45 to 50 Gy over 25 to 30 fractions to the elective clinical target volume (CTV). [24] To compare the dosimetric results of helical tomotherapy (HT) and volumetric arc therapy (VMAT) in the treatment of anal cancer. [25] Treating multiple lesions synchronously using a single‐isocenter volumetric arc therapy (VMAT) plan would be more efficient with the use of the most recently adopted photon optimizer (PO) MLC algorithm and improve the patient comfort. [26] The introduction of new techniques in photon RT, such as image-guided RT (IGRT), intensity-modulated RT (IMRT), volumetric arc therapy (VMAT) and stereotactic body RT (SBRT) was already effective in reducing side effects. [27] METHODS Forty patients treated with definitive (n=27) or adjuvant (n=13) RT using volumetric arc therapy between August 2014 and October 2015 for squamous cell carcinoma of the head and neck were included. [28] Four patients were chosen with intensity-modulated radiotherapy (IMRT) and volumetric arc therapy (VMAT) for in vivo dosimetry. [29] Advanced radiotherapy treatments like Intensity Modulated Radiotherapy (IMRT) and Volumetric Arc Therapy (VMAT) doesn't require a flat radiation field, and hence the flattening filter could be removed. [30] Today, because of the evolution of skills and technologies, the mainly adopted radiation treatment in this patient setting is intensity-modulated or volumetric arc therapy, which are associated with image-guided targeting. [31] Volumetric arc therapy (VMAT) for lung stereotactic body radiotherapy (SBRT) is challenging due to both breathing-induced motion and the dynamic components of the linear accelerator. [32] Patients with LN positive-only metastases were offered curative therapy using 3 months androgen deprivation therapy (ADT) followed by DE-IMRT (using volumetric arc therapy), and 3 years adjuvant ADT. [33] Purpose Intensity‐Modulated Radiation Therapy (IMRT), including its variations (including IMRT, Volumetric Arc Therapy (VMAT), and Tomotherapy), is a widely used and critically important technology for cancer treatment. [34] Methods: Patients included in the study had localized prostate cancer (cT1c-T3bN0M0) and were randomly assigned to mild hypofractionated (72 Gy in 32 fractions, arm1) or conventionally fractionated (74 Gy in 37 fractions, arm2) radiation therapy treatment with Volumetric Arc Therapy technique. [35] 4Gy) and this was delivered by a modulated volumetric arc therapy technique in ten patients and conformal tridimensional radiotherapy in two patients. [36] Purpose To analyze the differences in toxicity and biochemical relapse-free survival with hypofractionated radiotherapy with three-dimensional radiotherapy (3D-CRT) or volumetric arc therapy (VMAT) for prostate cancer taking into account comorbidity measured using the Charlson Comorbidity Index (CCI). [37] The goal of this study is to characterize the location and the magnitude of extrafocal dose regions in the case of three-dimensional conformal radiotherapy and volumetric arc therapy, to apply this information to clinical treatment cases, and to provide mitigation strategies. [38] 7 Gy in 7 fractions using volumetric arc therapy (VMAT) [1]. [39] Intra-fraction motion of the prostate was recorded during 721 fractions of image guided radiotherapy (IGRT) in 28 patients, 14 of which were treated by intensity modulated radiation therapy (IMRT), and 14 of which were treated by volumetric arc therapy (VMAT). [40] Volumetric arc therapy (VMAT) can effectively treat disease on circumferential surfaces while minimizing dose to the core structures. [41] BackgroundThis study set out to evaluate the effect of dose rate on normal tissues (the lung, in particular) and the variation in the treatment efficiency as determined by the monitor unit (MU) and energy applied in Linac-based volumetric arc therapy (VMAT) total marrow irradiation (TMI). [42] While the positioning for X-ray imaging allows tolerances of several millimeters since typically rather big areas are imaged, the required accuracy for CT-imaging and especially classical radiation therapy, Volumetric Arc Therapy (VMAT), Intensity-Modulated Radiation Therapy (IMRT) and 3D Conformal Radiation Therapy (3D CRT) for cancer treatment is much higher. [43] Purpose To assess the feasibility of using portal dosimetry (PD) for pre‐treatment quality assurance of single target, flattening filter free (FFF), volumetric arc therapy intracranial radiosurgery plans. [44] 5), and volumetric arc therapy on a linac (VMAT) calculated with either the conventional optimizer or with the Varian HyperArc™ solution. [45] Today, because of the evolution of skills and technologies, the mainly adopted radiation treatment in this patient setting is intensity-modulated or volumetric arc therapy, which are associated with image-guided targeting. [46] Our purpose was to evaluate sliding‐window IMRT (SW‐IMRT) and volumetric arc therapy (VMAT) in planning target volume (PTV) coverage and dose to organs‐at‐risk (OAR). [47] In this study, dosimetric measurements of small sized brain tumors irradiated in CONE- based linear accelator (linac) and the volumetric arc therapy (VMAT) linac modalities were performed with EBT3 film. [48] Volumetric arc therapy was used for treatment delivery (35 Gy delivered in 5 weekly fractions of 7 Gy each), and cone beam computed tomography with soft tissue matching (no fiducial placement) was used for daily image guidance. [49] Volumetric arc therapy (VMAT; RapidArc®, Varian Medical Systems) was used to deliver 52. [50]목표는 세포 저산소증의 검출에 가장 적합한 PET 방사성 의약품을 식별하고 강도 변조 방사선 요법(IMRT) 및 체적 아크 요법(VMAT) 계획의 이점을 인식하는 것이었습니다.
