The field of radiotherapy (RT) has benefited substantially from advancements in Image-Guided Radiotherapy (IGRT) in the past 15 years. IGRT now constitutes the integration of a wide range of imaging technology with modern RT delivery systems that include 3D anatomical and functional-based imaging for tumor volume identification, 3D target volume localization, and motion management information f...

PURPOSE To evaluate Lipiodol as a liquid, radio-opaque fiducial marker for image-guided radiation therapy (IGRT) for bladder cancer. MATERIALS AND METHODS Between 2011 and 2012, 5 clinical T2a-T3b N0 M0 stage II-III bladder cancer patients were treated with maximal transurethral resection of a bladder tumor (TURBT) and image-guided radiation therapy (IGRT) to 64.8 Gy in 36 fractions ± concurr...

We would like to compare the effectiveness of image-guided (IGRT) and intensity-modulated (IMRT) radiotherapy to spare the larynx in head and neck cancer patients. A retrospective review of 48 patients undergoing radiation for non-laryngeal and non-hypopharyngeal head and neck cancers. Mean laryngeal and hypopharyngeal dose was compared between 11 patients treated with IMRT and 37 patients trea...

Współczesnym złotym standardem leczenia nowotworów z wykorzystaniem radioterapii, jest wykorzystanie do pozycjonowania pacjenta na stole terapeutycznym, obrazowania wiązką promieniowania jonizującego o kilowoltowym lub megawoltowym efektywnym potencjale przyspieszającym - wobec tego pacjent narażony dodatkową dawkę. Zgodnie zasadą ALARA, ważne jest, aby osiągnąć pożądany efekt kliniczny przy za...

Sectional imaging is integrated in each link of the modern radiotherapy chain, from diagnostic procedures to target volume definition to treatment planning, dose delivery, and verification. While CT is widely used for modern EBRT, including intensity modulated radiotherapy (IMRT) and image-guided radiotherapy (IGRT), MRI represents the gold standard for IGBT for gynecological malignancies (see ...

Radiation therapy plays an important role in cancer treatment. It is well known that good local control is achieved when planned dose of radiation is delivered to the target. Recent advances in technology, in particular in image guided radiation therapy (IGRT), has significantly improved the accuracy of target localization for daily radiation treatment. Daily localization of the target is criti...

Radiation therapy is a widely used cancer treatment that utilizes high-energy radiation to target and destroy cells. However, challenges such as resistance exposure of healthy tissue the can limit its effectiveness. In this article, we explore various methods have been developed increase effectiveness in treatment. These include fractionation, image-guided (IGRT), radio sensitizers, hyper immun...

Radiation therapy has come a long way from treatment planning based on orthogonal radiographs with large margins around tumours. Advances in imaging and radiation planning software have led to three-dimensional conformal radiotherapy and, further, to intensity modulated radiotherapy (IMRT). IMRT permits sparing of normal tissues and hence dose-escalation to tumours. IMRT is the current standard...
