Tx Equipment
100

Has many forms and is used to compare external set-ups marks and internal anatomy to the treatment plan

IGRT

100

2D imaging that provides better soft tissue contrast

KV imaging

100
Radiation is on the when target is within the treatment volume, off when it is not

Gated treatments

100
"Delivery of a well-defined beam to hard-to-reach places"

SRT

200

Uses the Cartesian coordinate system and an external 3D frame of reference

SRT

200
Table is moved 180 degrees image is obtained with stationary table. Employs two separate units

CT on rails

200

ACT data set that account for respiratory motion

4D CT

200

Cyclotron Particles

Protons

300

Is used to manage the movement of organs as result of patient breathing

Respiratory Motion Management
300

3D imaging. Uses a wider x-rays beam for scanning. can scan a larger volume. generated scatter can degrade quality of images

CBCT

300
Area or region at the beam's edge where the radiation intensity falls to 0

Penumbra

300

Dmax of a Cobalt 60

0.5cm

400

Type of treatment that uses heavily charged particles with rapid dose fall-off

Proton Therapy

400

May be internal or external. Uses various imaging modalities to document location

fiducials

400

Two common methods for screening of prostate cancer

DRE and PSA Blood test

400

Least skin sparing equipment utilized in Radiation Oncology

Superficial treatment Unit
