Linac QA
Recommended Tests
TG142 based QA program for linear accelerators including multileaf collimation (MLC), asymmetric jaws, dynamic and virtual wedges, and electronic portal imaging devices (EPIDs). Quality assurance of image guidance devices such as cone-beam CT (CBCT), static kilovoltage (kV) imaging, respiratory gating, SRS, SBRT, IMT and TBI procedures./p>
Linac QA Software
RIT software currently has 31 patents in Rotational Therapy, IMRT, TomoTherapy®, CyberKnife®, and conventional therapies, all of which have advanced the standard of QA in radiation therapy. These include, but are not limited to: Plan-Based Calibration, MLC Step Wedge, Automated Sensitometry Correction, Calibrations Embedded in Images, Image Alignment, and 3D Stereotactic Alignment Isocenter Analysis (Winston-Lutz).
Phantoms
Phantoms for EPID, OBI / XVI, Light to Radiation Field, kV and MV Coincidence and Winston-Lutz Beam Isocenter Phantoms
Recommended tests for Linac QA
Beam Outputs QA
Winston-Luzt test, Output Constancy, Symmetry, Flatness, Light to Radiation Field Coincidence, Profiles, Percent Depth Dose, Wedges, Star Shot
Multileaf Collimator (MLC) QA
RIT113 provides several automated multi-leaf collimator quality assurance tests. The software then analyzes this pattern and provides statistics on uniformity and leaf position, as well as other statistics.
EPID QA
Testing EPID image quality for Elekta, Varian linac with EPID phantom and RIT software.
