MUVerify provides an independent second check of the calculated monitor units or time in static non IMRT X-ray radiotherapy treatment fields. Using the definitions of the AAPM Task Group 114, MUVerify computes “MU verification” (MUV). Several authors and organizations have discussed the need of a second independent check and the present consensus is that MUV remains necessary. It is important to note that MUVerify computes “MU verification” (MUV), only for the purpose of confirming “primary MU”, and is not intended for the delivery of radiation. MUVerify implements simple and well known methods for computing monitor units. One of the main goals of MUV is provide independent results, unrelated to main planning systems (TPS). In the pursuit of independence we have included some generic dosimetry information to avoid using the same data of your TPS. The “generic dosimetry data” is based on a library of PDD, NPSF and other parameters representative of typical photon beams. The inclusion of a generic dosimetry library frees the user from entering extensive tables, which is cumbersome for a mobile app and error prone. The beam quality index for searching and interpolation in the dosimetry library is TPR20/TPR10. MUVerify can be used for LINAC as well as Cobalt-60 therapy units. All computations are for the central axis. Radiation fields allows the inclusion of wedge and trays. The wedge can be physical or EDW. When using a physical wedge, MUVerify computes a generic beam hardening factor (BHF) based on linear regression of BHF as a function of wedge factor for several depths in water for different beam energies. To compute the wedge factor in case of EDW a method based on Gibbons’ algorithm (Med.Phys.25.1998) was implemented. For the case of shaped fields (with cerrobend blocks or MLC) the user can enter the effective field size. Regarding heterogeneity corrections only the lung is considered; an optional parameter sets the thickness of lung that the beam is crossing. MUVerify keeps commissioning as simple as possible. The input of measured data is minimalistic if compared with a full-fledged typical TPS. Input of the required data should not take more than 15 minutes and all the information is part of routine in a radiotherapy department, so no exclusive measurements will be necessary for MUVerify. Once a machine is created inside your device (iPhone, iPad or iPod) it can be mailed to all colleagues in the department, avoiding redundant work. The MUV value resulting from MUVerify is compared with the primary MU from the TPS. For most of the fields the agreement should be better than 2%, but for complex fields using a thick physical wedge or in the presence of lungs the deviation could be greater. The adoption of an action level is left to the user, but a recommendation of 5% is widely accepted. ## Key features - Independent monitor unit verification - Generic dosimetry data library - Supports LINAC and Cobalt-60 units - Includes wedge and tray calculations - Handles shaped fields and lung heterogeneity - Minimalistic data input for commissioning ## Frequently asked questions about MUVerify ### What is MUVerify used for? MUVerify is used to perform an independent second check of calculated monitor units (MU) for X-ray radiotherapy treatment fields. It helps confirm primary MU values for treatment safety. ### Does MUVerify require specific measurements for setup? No, MUVerify requires minimalistic data input, all of which is part of routine radiotherapy department information. No exclusive measurements are necessary, and setup should take no more than 15 minutes. ### What kind of radiotherapy units does MUVerify support? MUVerify can be used for both LINAC (Linear Accelerator) and Cobalt-60 therapy units, providing verification for central axis calculations. ### How accurate are MUVerify's calculations compared to primary planning systems? For most fields, the agreement between MUVerify and the primary MU from the planning system should be better than 2%. Deviations may be greater for complex fields, thick physical wedges, or in the presence of lungs. ### Can MUVerify handle complex field shapes and heterogeneity? Yes, MUVerify allows for shaped fields using cerrobend blocks or MLC by entering the effective field size. It also includes an optional parameter for lung heterogeneity corrections. ### What is the pricing for MUVerify? MUVerify is a paid application, priced at $9.99. There are no in-app purchases or subscriptions required. ### What devices is MUVerify compatible with? MUVerify is available for iPhone and iPod devices. It is designed for mobile use within a radiotherapy department. ### How often is MUVerify updated? The latest version of MUVerify is 1.4, last updated on December 13, 2025. Updates ensure the app remains current with relevant standards and features. ## Version history (last 5 releases) ### 1.4 — 2025-12-13 Age rating updated. ### 1.3 — 2025-03-26 Compatibility update for latests versions of iOS. ### 1.2 — 2020-01-28 Compatibility update for iOS 13, including support for Dark Mode. Current Activity value exhibited in the Monitor Units screen. This information is useful for Cobalt machines. ### 1.1 — 2016-08-10 Bug corrected in the Machine creation or edition that caused the machine data corruption if the user device had the 12 hours clock set manually. Bug corrected in the Field screen related to the selection of the machine. The app crashed when the user changed from a machine with wedges and/or trays to a machine without them. ### 1.0 — 2013-03-30 No release notes. ## Apps similar to MUVerify | App | Rating | Price | Category | | --- | --- | --- | --- | | [Hearing Aid Ear Booster Loud](https://appshunter.io/ios/app/hearing-aid-ear-booster-loud/id6596743156) | 4.3 (468) | Free | Medical | | [OsiriX HD](https://appshunter.io/ios/app/osirix-hd/id419227089) | 2.8 (49) | Free | Medical | | [Lifespan Therapy](https://appshunter.io/ios/app/lifespan-therapy/id1544657761) | 4.8 (10) | Free | Medical | ## More apps by Mevis Informática Médica Ltda. - [iDCalc](https://appshunter.io/ios/app/idcalc/id556863722) - [StereoCheck](https://appshunter.io/ios/app/stereocheck/id566866809) - [StereoCheckRM](https://appshunter.io/ios/app/stereocheckrm/id944791423) - [CheckBRW](https://appshunter.io/ios/app/checkbrw/id1391907954) All apps by Mevis Informática Médica Ltda.: https://appshunter.io/developer/556863725 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
