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 inputs, outputs, and field-to-field comparisons offers quick review and easy editing of plans.

  • Electron MU calculations
  • Advanced diode support

New! CyberKnife plan verifications

Fast and easy verification of plan monitor units (MU) and dose for both composite and per projection analysis.

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.

  • Multiple calculation points
  • Sp correction factor for accounting for flash

In-depth IMRT patient QA

Independent verification of complex IMRT plans in minutes, not hours. The treatment planning system predicted fluence is imported giving you a direct comparison to IMSure QA calculated fluence from any of six different methods, including gamma map comparisons, difference maps, and a patented correlation coefficient for each beam.

  • Histograms for map analysis

Features and benefits

Intuitive MU Dose Calculations

  • Check MU or specific-point dose quickly and easily
  • A single screen for inputs, outputs, and field-to-field comparisons offers quick review and easy editing of plans

Cyberknife Plan Verification

  • Composite and per projection verification of plan monitor units (MU) and dose

Accurate MU dose calculations of IMRT

  • Multiple dose calculation points, including off axis measurements from 3 effective sources
  • 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 linac parameters are accurately modeled

Simple physics interface and reporting

  • Supports unlimited machines, energies, treatment planning systems and record & verify systems
  • Completely characterizes output aspects from linear accelerator for simulated dose delivery and easily imports TMR, OF, OCR, PDD (electrons), cone factor (electrons), MLC, jaws, wedges including dynamic wedge angles, and head scatter sources
  • Easily imports TPS fluence maps, MLC leaf sequence files in DICOM RT and RTP format, and provides graphical representation of beam data
  • Provides hard copy output for billing and patient documentation and electronic output for paperless record keeping
  • 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 to either the true patient plan or a phantom plan
  • Compares plans in six different ways, including difference maps, gamma maps, and histograms
  • Compares dose at one or multiple 3-dimensional points on a field-to-field basis as well as composite dose
  • 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

Validated results

  • IMSure QA is proven as effective as measurements and TPS
  • The performance of IMSure QA Software has been verified in multiple publications
