Radiation Physics Sample Clauses

Radiation Physics. Objective: The purpose of this module is to comprehend the basic principles of radiation physics in order to apply them to medical physics. The interaction of photons, charged particles and neutrons with matter is described. The essential properties of atomic nuclei are also described. Characterization of attenuation must be understood. Content: • Introductory concepts to modern physics • Atomic and nuclear structure o Basic principles • Radioactivity o Radioactivity decay mechanisms o Radioactive decay law ▪ Half-life ▪ Activity ▪ Secular equilibrium • Basic nuclear interactions • Interaction of radiation with matter o Photon interactions ▪ Photoelectric interaction ▪ ▇▇▇▇▇▇▇ ▪ Pair production ▪ ▇▇▇▇▇▇▇▇ and Thomson ▪ Attenuation ▪ Cross-sections and relative importance of interaction mechanisms o Charged particle interactions ▪ Elastic scattering ▪ Inelastic scattering (collisional and radiative processes) ▪ Stopping power concept ▪ Continuous slowing down approximation (CSDA) and range concept ▪ ▇▇▇▇▇ peak concept o Neutron interactions ▪ Energy classification ▪ Elastic and inelastic interaction ▪ Interaction law (attenuation) • Introduction to Monte Carlo methods

When respiratory services are provided in your home, as part of a home care program, durable medical equipment, supplies, and oxygen are covered as a durable medical equipment service.

  • Outpatient Dental Anesthesia Services This plan covers anesthesia services received in connection with a dental service when provided in a hospital or freestanding ambulatory surgical center and: • the use of this is medically necessary; and • the setting in which the service is received is determined to be appropriate. This plan also covers facility fees associated with these services. This plan covers dental care for members until the last day of the month in which they turn nineteen (19). This plan covers services only if they meet all of the following requirements: • listed as a covered dental care service in this section. The fact that a provider has prescribed or recommended a service, or that it is the only available treatment for an illness or injury does not mean it is a covered dental care service under this plan. • dentally necessary, consistent with our dental policies and related guidelines at the time the services are provided. • not listed in Exclusions section. • received while a member is enrolled in the plan. • consistent with applicable state or federal law. • services are provided by a network provider.

  • Durable Medical Equipment Durable Medical Equipment is equipment that is Medically Necessary for treatment of an illness or Accidental Injury or to prevent further deterioration. This equipment is designed for repeated use and used to treat a medical condition or illness, and includes items such as oxygen equipment, functional wheelchairs, and crutches. Durable Medical Equipment may require Prior Authorization. Only Durable Medical Equipment considered standard and/or basic as defined by nationally recognized guidelines are Covered.
