Online magnetic resonance-guided radiotherapy (oMRgRT) represents one of the most innovative applications current image-guided radiation therapy (IGRT). The revolutionary concept oMRgRT systems is ability to acquire MR images for adaptive treatment planning and also online imaging during delivery. daily strategies allow improve targeting accuracy while avoiding critical structures. This ESTRO-A...

conclusion pair therapy is an effective minimally invasive treatment for gharbi type i-iii hepatic hydatid cysts. it is a cost effective and safe procedure with significant reduction in the duration of hospital stay. results ten patients (66.7%) had gharbi type i cysts, two (13.3%) had type ii and three (20%) had type iii cysts. all the patients (100%) showed reduction in cyst size over a 3-6 m...

Prostate cancer (CaP) is the most commonly diagnosed cancer in males. There have been dramatic technical advances in radiotherapy delivery, enabling higher doses of radiotherapy to primary cancer, involved lymph nodes and oligometastases with acceptable normal tissue toxicity. Despite this, many patients relapse following primary radical therapy, and novel treatment approaches are required. Met...

Radiotherapy has a well-established role in the management of head and neck cancers. Over the past decade, a variety of new imaging modalities have been incorporated into the radiotherapy planning and delivery process. These technologies are collectively referred to as image-guided radiotherapy and may lead to significant gains in tumor control and radiation side effect profiles. In the followi...

PURPOSE Image-guided radiotherapy (IGRT) is becoming increasingly important in the planning and delivery of radiotherapy. With the aim of implementing the key technologies in a flexible and integrated way in IGRT for accurate radiotherapy system (ARTS), a prototype system named as ARTS-IGRT was designed and completed to apply main principles in image-guided radiotherapy. METHODS The basic wor...

Background Intensity-modulated stereotactic radiotherapy achieves improvements in the ability to produce conformal stereotactic dose distributions by modulation of the intensity of individually delivered beamlets of radiation. Image-guided intensity-modulated stereotactic radiotherapy has emerged as a new treatment option in the multidisciplinary management of metastatic and locally advanced ca...

BACKGROUND The cumulative dose was compared with the planned dose among fourteen patients undergoing image-guided, intensity-modulated radiotherapy of the prostate bed. Moreover, we investigated the feasibility of adding dose tracking to the routine workflow for radiotherapy. METHODS Daily cone beam computed tomography was conducted for image-guided radiotherapy, and weekly cumulative deliver...
