Adjust your calibration files based upon your daily output factor. Inspecting calibration points is even easier with the new Calibration Datapoint Highlighter. Just click on any point in the calibration table and the associated value on the curve will be highlighted.

You are Going To Love This RIT's patented Plan Base Calibration routine gives you the ability to make quick relative or absolute comparisons between any dose map and your Film, EPID, CR and Ion Chamber Array images! Using any dose map images (no special patterns needed), another image can be calibrated. Overlaying this calibration with an existing absolute calbration can give you an idea of the overall accuracy. This technique can be used to eliminate field size dependencies in film, EPID and CR images. It can also be used with an ion chamber array to produce fast absolute dose calibration at a multitude of points.

This routine was developed in cooperation with Dr Arthur Olch, PhD, Chief of Physics, Children's Hospital, Los Angles, CA. "Validation of a Plan-based Calibration Method for Relative Dosimetry", A. Olch, AAPM 2006 Meeting, Poster paper #SU-FF-T-499.

Use this RIT patented technique to calibrate to dose in just 2 films! RIT113 supplies an MLC file to generate a step wedge in dose. This step wedge has 13 dose steps on a single film. This dose step film combined with an unexposed film (for zero) dose is all you need for a complete calibration curve. You can also generate your own MLC step wedge file with more than 13 steps. Alternatively, you can use your primary collimators to direct the beam to a narrow band, then step your couch to achieve the same steps of dose. For even more accurate dose conversion, multiple MLC step calibration films (at different dose levels) may be combined using the Calibration Merge Utility into one super calibration film. For those using compensators, .decimal¨ now makes a compensator step wedge for our patented calibration routine that may be purchased from RIT. In addition, this can be used with the Automated 21 point Film Processor Correction routine to reduce the number of calibrations needed.

Import your PDD table for use in any parallel calibration routine. This editor makes it easy to change, add, or remove values. Many PDD tables can be saved and recalled for calibration.

This graphical calibration editor lets you easily select dose points on a parallel image and assign dose values. You may also import a PDD table with these values.

Develop standard perpendicular dose curves quickly and easily from two or more films. Zero dose entry has been simplified to speed up the last part of this process.

Since the iView panel is very linear, you only need three dose points to develop a calibration curve. Use measured doses from three or more images to quickly develop this calibration curve.

The Varian aS units can be calibrated with a simple wedge (using parallel calibration), the MLC step wedge (for one shot calibration), or several perpendicular exposures. It's your choice!

Easily calibrate your Kodak / Carestream CR images to dose with at little as three uniform images at different dose levels.
