Radiation Oncology/Tomotherapy


 * Patients scanned across a modulated strip-beam
 * Only one “slice” (Greek prefix “tomo-”) of the target exposed at any one time by the linear accelerator (linac) beam
 * The three components distinctive to this modality:
 * A collimator pair that defines the length of the strip
 * A binary multileaf collimator whose leaves open and close during treatment to modulate the strip’s intensity
 * A couch that scans the patient across the beam at a fixed speed the during treatment delivery
