Expands patient-first treatment like no other system in the world
Image guided, intensity modulated radiation therapy (IG-IMRT), featuring best-in-class clinical workflows and highly conformal and homogenous treatments enabled by a unique ultra-fast multi-leaf collimator (MLC). The Radixact®波多野结衣高清无码中文 System shapes radiation to the tumor while sparing normal, healthy tissue.
波多野结衣高清无码中文Conformal, homogenous coverage
TomoDirect provides non-rotational delivery of beamlets from fixed gantry angles, enabling highly efficient and precise 3D conformal radiation therapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) capabilities. Continuous couch motion enhances treatment delivery over the longest treatment fields in the industry. The advantages of TomoDirect for breast treatments over competitive modalities have been shown in published planning comparisons.1-3
Combined with TomoEDGE™ dynamic jaws, TomoDirect provides efficient treatments and highly conformal dose distribution in both whole breast and whole breast with supraclavicular regional lymph nodes4.
- Highly customized treatment planning: Create treatment plans that include 2 to 12 target-specific gantry angles and user-defined levels of modulation
- Interactive 3D-CRT: Treatment planning with daily 3D-CT image guidance to support margin reduction and positioning accuracy
- Longest treatment fields in the industry: Eliminates multiple isocenters and field junctions that are time-consuming to plan and deliver and can lead to hot and cold spots.
Outstanding precision & dose fall-off
- Beam expansion: Open additional leaves beyond the target to compensate for target motion (up to five leaves per angle)
- TomoEDGE™ Dynamic Jaws: Dynamically conform to the target in the craniocaudal direction, producing sharp dose fall-off for precise sparing of normal tissue and increased throughput
- Fastest leaf speed in the industry: Produces more modulation compare to other IMRT delivery techniques.
