A true innovation
A new detector technology that combines the signal stability and signal reproducibility of a large ionization chamber with the spatial resolution and spatial sensitivity of film. A new detector technology that measures the accuracy of the treatment beam at every control point. A new detector technology with unrivaled precision for every clinically relevant influence on the treatment beam. A new detector technology like no other before.
Patented design for a new verification approach. Patented until 2027.
Simplicity re-invented
One single ionization chamber. The ultimate simplification.
Uniquely designed to measure every field size, every field shape, every dose, every dose rate, every energy, at any field position. At every control point. With unrivaled precision. A new level of detection accuracy. A new level of detection speed. A new level of quality assurance significance.
Detect any error in real-time during the patient treatment. When it really matters.
Simple. Robust. Stable.
One ionization chamber. Three electrodes. Two polarizing electrode. One collector electrode. Each electrode is made of 1.5mm thick aluminum plates. Each aluminum plate is 26cm x 26cm. Covering 40cm x 40cm field size at isocenter.
Designed for everyday use. Monitor every fraction. Every beam. Every control point. Everything. All the time.
3 aluminum plates. Embedded in a guard ring. Fixed into the acrylic frame with 14 screws. No radiation damages. No deterioration. No dose rate dependency. No calibration. No maintenance. Guaranteed.
100% active detection area
Uniquely precise. For every field size. At any location.
The patented IQM detector design provides 100% active detection area. Every spot of the detector measures radiation. Every beam segment creates a unique and highly specific signal. Even the smallest stereotactic beam segment at any off-axis position is measured with an unrivaled accuracy and specificity. Particularly suited for the verification of SRT and SBRT techniques.
The smaller the beam segment the higher the sensitivity for any possible deviation. Superior precision. No restrictions.
Accuracy by design
Continuous spatial resolution. Unmatched spatial accuracy.
A linearly varying electrode separation. Increasing from 2mm to 2cm in leaf motion direction. Continuous spatial resolution for a new level of measurement accuracy. Provides a significantly higher spatial sensitivity than the discrete spatial resolution of conventional 2D or 3D Arrays. No matter how small or large of a field size. No matter what shape of a field. No matter how far off-axis the field is located.
The IQM detector technology measures highly specific signals for even the most complex treatment techniques. Every time. All the time.
Precision. Significance. New defined.
The IQM detector technology defines a new level of precision.
Every beam related error is detected in real-time. During the treatment fraction. Clinically relevant deviations are detected before they can potentially harm your patient. Quality Assurance that truly impacts patient safety. Quality Assurance that really matters.
A new level of significance.
Wide dynamic range
IQM provides a wide signal range: Starting with a minimal signal rate of 50 counts per minute. 800 to 1.500 counts/min. for a small VMAT beam segment. 5.000 to 8.000 counts/min. for a step&shoot IMRT beam segment. 230.000 counts/min. for a 10cm x 10cm x06 beam calibrated to Dmax delivering 100 MU. 305.000 counts per minute for a 10cm x 10cm x06 beam calibrated to a reference depth of 10cm delivering 100 MU. And more than 4.000.000 counts/min. for a 40cm x 40cm x06 beam delivering 100MU.
Detects any dose change. Immediately.
Measure every dose from 1/10 MU per sqcm up to unlimited. Completely dose rate independent.
The IQM signal varies linearly with the applied dose output. Any change in dose output proportionally changes the IQM signal. A 2% change in dose output changes the IQM signal by 2%. A 50% change in dose output changes the IQM signal by 50%.
Every energy. Every dose. Every dose rate. All the time.
Covers every field size. No limitations.
The IQM detector design encloses every field size. From the smallest atereotactic field size at any off-center location up to a 40cm x 40cm field sIze. IQM measures a highly specific signal for every field size.
IQM detects any field size variation both in X- and Y-direction. IQM shows a significant signal variation when changing the field size. A change in field size from 1cm x 1cm to 2cm x 2cm changes the IQM signal by approx. 400%.
Measures every field shape.
And detects even the slightest change.
IQM shows a high sensitivity for even the smallest changes. A 1mm single leaf change (in or out of the beam) creates a 1% signal change. IQM detects 1mm parallel shifts of two opposed leafs. IQM is compatible with any multileaf collimator design. IQM has already been utilized for picket fence tests.
Sensitive at every field location.
Without exception.
Detects beam position changes with an unrivaled sensitivity. A 1mm change of beam placement creates a 0.5% signal change. IQM detects beam position changes both in x- and y-direction. IQM detects beam position changes that remain unnoticed with today’s conventional verification tools.
Every time. Without exception.
Highest spatial resolution.
In its most minimal form.
