High Definition Radiation Therapy (HDRT)
Radionics HDRT utilizes
new LINAC-based CT imaging to meet the
challenges of extracranial stereotaxy including patient repositioning
and internal anatomical shifts.
Radionics HDRT integrates:
|
|
 |
 |
 |
| High Resolution IMRT: XKnife IMRT
utilizes high resolution MLC and MMLC technology to deliver
optimal dose coverage for all targets. |
Image Guided Accuracy: Radionics
stereotactic ImageFusion used together with LINAC-based CT guidance
yields daily target shifts. |
Stereotactic Precison: High
precision immobilization, localization, and repositioning distinguishes
Radionics HDRT from conventional IGRT. |
|
|
Without HDRT, internal anatomy can
shift up to 5 mm, even with rigid immobilization. In this case
the spinal cord would receive significant dose.
|
With HDRT, daily isocenter shifts
can be automatically calculated and applied to ensure target coverage
and structure sparing.
|
Dose volume histograms compare
the uncorrected pre-plan with the HDRT plan.
