End-to-End SBRT Phantom

Workflow Step

Modality

The End-to-End SBRT Phantom is a single tool for high-accuracy end-to-end commissioning and routine QA necessary for the high dose per fraction associated with SBRT deliveries.

Proven Tissue Equivalence
Linear attenuations of the simulated tissues are within 1% of actual attenuation for water and bone, and within 3% for lung from 50 keV to 15 MeV. The phantom contains a 3D anthropomorphic removable spine with cortical and trabecular bone as internal landmarks

Daily System Checks
The E2E SBRT Phantom contains multiple targets and alignment marks for verifying that imaging, localization, and targeting systems are aligned. This is a critical need for accurate delivery of these high-dose treatments.

OSL Dosimeters
Three OSL pockets in the right lung provide high-resolution dosimetry measurements to the target and spinal cord in a single delivery.

Radiochromic Film

The removable split spine allows for film measurements in the sagittal orientation in the inferior half of the spine rod. Film can also be placed in the sagittal slice in the spine and lung inserts.
