Radiation prescription
±The documentation of treatment through radiographic or electronic imaging devices
±Taken on treatment unit with patient in treatment position
±Compared with reference images
±Clinical acceptance or changes are generated
±Modifications made and documented, if necessary, before treatment
,Give this one a try later!
Verification images
The ______ provides info to the RT regarding the status and operation of the treatment
unit

console
Radiation therapist responsibilities
Give this one a try later!
±Knowledge of treatment effects with radiation
±Tumor-lethal doses
±Limits of radiation tolerance to normal tissue
±Knowledge of treatment plan and changes in the course of treatment
Allows the transmission of a predetermined percentage of treatment beam to a
portion of a treatment field
Structures that have varying radiosensitivity can be treated at different dose rates
even though they are close to each other
Whole abdomen treatment

, Transmission filters
°Is a calibrated device that fits into the collimator
Give this one a try later!
BB Tray/graticule
During treatment
Give this one a try later!
intrafraction
±Uses flat panel kV images and a diagnostic x-ray tube
±Provides better contrast than MV imaging
±Does not allow comparison of the blocked field
Give this one a try later!
On board imager
When an area of low dose is acceptable at and near the surface.
Produces a low dose area or cold spot, this can be reduced by feathering the gap
