A fast model for prediction of respiratory lung motion for image-guided radiotherapy: A feasibility study
Background: The aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one CT dataset. Materials and Methods: For each of six patients with different thorax sizes, two sets of CT images were obtained in single-breath-hold inhale and exhale stages in the supine position. The CT images were then ...
متن کاملSystem for MRI guided Radiotherapy
The adverse side effects of gamma-ray radiotherapy can be reduced significantly by combining the treatment system with a real-time imaging system, used to precisely steer the radiation beam. MRI is a particularly attractive imaging modality for this, due to its excellent soft tissue contrast. A project is underway to combine a cylindrical, closed bore high-field MRI system with a 6 MeV Linac ra...
متن کاملMR-guidance – a clinical study to evaluate a shuttle- based MR-linac connection to provide MR-guided radiotherapy
BACKGROUND The purpose of this clinical study is to investigate the clinical feasibility and safety of a shuttle-based MR-linac connection to provide MR-guided radiotherapy. METHODS/DESIGN A total of 40 patients with an indication for a neoadjuvant, adjuvant or definitive radiation treatment will be recruited including tumors of the head and neck region, thorax, upper gastrointestinal tract a...
متن کاملSU-E-J-36: A Flexible Integration of Key Technologies in Image-Guided Radiotherapy for Accurate Radiotherapy System (ARTS-IGRT).
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...
متن کاملMR-guided multi-atlas based synthetic CT for MR-only radiotherapy of head and neck cancer patients
S71 ______________________________________________________________________________________________________ provided by dual-energy CT (DECT) compared to singleenergy CT (SECT) can be clinically used to reduce CT-based range uncertainties and to analyze intraand interpatient tissue variations. First, a DECT scan protocol was optimized and clinically introduced. Second, in a first analysis patien...
