SRS MapCHECK® is an advanced system for quality assurance (QA) in stereotactic radiosurgery (SRS/SBRT) that replaces the use of film and eliminates measurement subjectivity. The system provides fast, accurate, and fully digital testing, enhancing patient safety and clinical workflow efficiency.

Backed by numerous scientific publications, SRS MapCHECK has proven its clinical versatility, accuracy, and reliability. The system helps prevent treatment errors across a wide range of radiation delivery systems and stereotactic radiosurgery technologies.

Irradiate from Any Angle

In combination with the StereoPHAN™ phantom, the SRS MapCHECK system utilizes patented angular dependence correction technology, allowing for precise dose measurements regardless of the irradiation angle.

The system automatically accounts for:

• Angular dependence of detectors
• Field size
• Pulse rate

This ensures high measurement accuracy for any delivery geometry.

Flexibility, Speed, and Accuracy

SRS MapCHECK provides accuracy comparable to film dosimetry but is significantly faster and more convenient.

The system effectively detects:

• Output factor errors
• MLC errors
• Grid size errors

This helps avoid the most common sources of error in SRS treatments.

Quality Assurance in Just 10 Minutes

Using SRS MapCHECK significantly simplifies the QA procedure. The process involves only a few steps:

• Insert the SRS MapCHECK into the StereoPHAN™ phantom
• Perform the irradiation according to the treatment plan
• Compare the absolute planar dose with the TPS plan

High Detector Resolution

The SRS MapCHECK diode array features a 2.47 mm detector spacing, providing:

• 5 detectors in a 5 mm field
• The ability to measure the smallest clinically used fields

Additional Specifications:

• Detector resolution: 0.48 mm
• Patented angular dependence correction
• High-precision measurement of small fields

This makes the system ideal for the reliable quality control of SRS procedures.
