Radixact® expands the curative power of radiation therapy 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).
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.
Outstanding precision & dose fall-off
Tailoring Radiotherapy to Breast Cancer:
The Role of the TomoTherapy® System

TomoEDGE™ Dynamic Jaws
Total scheduled procedure time averages 10-15 minutes* with TomoEDGE dynamic jaws
*Includes set-up, full 3D imaging and average beam-on time of 4.5 minutes. Total procedure times are approximate and based on internal Accuray test data. Times may vary with various clinical situations.
“For postoperative breast irradiation with static TomoTherapy, the dynamic jaw mode was effective in reducing the treatment time and the doses of OARs in both of the plans of the whole breast with supraclavicular regional lymph nodes and those of the whole breast.”
