RIT Supported Phantoms Overview

L-Rad Phantom

Lightfield Radiation

Provides a low-cost solution for medical physicists to perform EPID-based radiation field size and light field coincidence checks. This lightweight phantom’s innovative design allows for both standard and asymmetrical radiation vs. light field tests, at a variety of field sizes.

Key Features

  • Perform EPID-based radiation vs. light field coincidence verifications, both standard and asymmetrical.
  • Verify couch movement, including three-dimensional travel and rotation.
  • Verify EPID scaling and travel, using the embedded BBs.
  • Verify field sizes: 5x5 cm, 10x10 cm, 15x15 cm, and 20x20 cm.
