Sample 1
Intensity modulated radiation therapy or “IMRT” means a treatment delivery utilizing a radiotherapy treatment plan optimized using an inverse or forward planning technique to modulate the particle or energy fluence to create a highly conformal dose distribution. This beam modulated treatment delivery can be accomplished either by the use of the computer controlled multi-leaf collimator or high resolution milled or cast compensators.

Related to Intensity modulated radiation therapy

  • Step therapy means a program for Insureds who take Prescription Drugs for an ongoing medical condition, such as arthritis, asthma or high blood pressure, which ensures the Insured receives the most appropriate and cost-effective drug therapy for their condition. The Step Therapy program requires that before benefits are payable for a high cost Covered Drug that may have initially been prescribed, the Insured try a lower cost first-step Covered Drug. If the prescribing Physician has documented with SHL why the Insured’s condition cannot be stabilized with the first-step Covered Drug, SHL will review a request for Prior Authorization to move the Insured to a second-step drug, and so on, until it is determined by SHL that the prescribed Covered Drug is Medically Necessary and eligible for benefit payment.
