IMSure QA™ Software

Fast, Precise

Unprecedented accuracy from the patented “3-Source Model” algorithm, easy standard plan MU checks and uniquely comparative IMRT Plan QA — no film, no phantom, no linac time required.

Intuitive MU Dose Calculations
Automate hand calculations of conventional plans or create simple plans with just a few clicks. A single screen for all inputs, outputs and field-to-field comparisons offers quick review and easy editing of plans.

Accurate IMRT Dose Calculations
The patented Stanford University “3-Source Model” considers the dose from the primary photon source, the primary collimator scatter and the flattening filter scatter resulting in extremely accurate dose calculations including those in high-gradient / low-dose regions common in IMRT.

In-Depth IMRT Patient QA
Independent verification of complex IMRT plans in minutes, not hours. The treatment planning system’s predicted fluence is imported giving you a direct comparison to

IMSure’s calculated fluence from any of five different methods, including Gamma Map Comparisons, Difference Maps, and a patented correlation coefficient for each beam.

Features

Intuitive MU Dose Calculations

  • Check MU or any specific-point dose quickly and easily
  • A single screen for all inputs, outputs and field-to-field comparisons offers quick review and easy editing of plans
  • Secondary dose-point calculations for diode support to predict and verify diode measurements

Accurate MU Dose Calculations of IMRT

  • Multiple dose calculation points, including off axis measurements from 3 effective sources
  • MLC leaf and sequence display
  • Patented 3-Source Model more accurately models high-gradient / low-dose regions of small fields common in IMRT
  • MLC leaf and jaw leakage are also considered so all linac parameters are accurately modeled

Simple Physics Interface & Reporting

  • Supports unlimited machines, energies, treatment planning systems and record & verify
  • Completely characterizes all output aspects from linear accelerator for simulated dose delivery and easy import of TMR from PDD, OF, OCR, MLC, Jaws, all wedges including dynamic wedge angles, all head scatter sources
  • Easily imports TPS fluence maps, and MLC leaf sequence files in DICOM RT and RTP format and provides graphical representation of beam data
  • Hard copy output for billing and patient documentation and electronic output for paperless record keeping (in U.S. use CPT Code 77300)

Fast IMRT Patient Dose Verification QA

  • Calculated fluence compares directly with the TPS predicted fluence resulting in accurate and in-depth patient plan QA analysis
  • Compare plans in five different ways, including Difference Maps and Gamma Maps
  • Compare dose at any 3-dimensional point within the treatment field as well as composite dose
  • IMSure QA proven as effective as measurements and TPS
Validated Results
  • The performance of IMSure QA Software has been validated in five publications (see below).
  • ACR Practice Guidelines for Intensity Modulated Radiation Therapy (IMRT) recommend an independent dose calculation method as an alternative to physical measurements once dosimetric accuracy of the planning/delivery system has been demonstrated.
