Total body irradiation (TBI) is a radiation therapy technique that treats the entire body rather than a localized area, most often used as part of conditioning before a stem cell or bone marrow transplant. Because the treatment field, distances, and session length differ from standard localized radiotherapy, TBI setups carry additional complexity that makes verification especially important.
What Makes TBI Different
TBI is typically delivered at an extended distance from the machine, with the patient positioned to receive a more uniform dose across the entire body, sometimes with shielding for sensitive organs.
Sessions can be longer, and small setup deviations have a greater chance of affecting the intended dose distribution compared to a small, localized field.
Why Verification Matters Specifically for TBI
Because TBI affects the whole body and is frequently used ahead of a transplant, accuracy at each stage of setup and delivery carries added weight.
Verification steps — confirming patient identity, setup parameters, and treatment progress — help ensure the plan delivered matches the plan intended, and create a record that supports later review.
Where Technology Supports the Process
- Confirming patient identity at the console before a TBI session begins
- Logging verification steps across a treatment that may involve multiple positions or fields
- Supporting the department’s quality assurance review after treatment
Quantaris Medical’s CNERGY TBI is built around these verification needs for total body irradiation workflows.
