A new detector technology that measures the accuracy of the treatment beam at every control point. A new detector technology that assesses every influence on the treatment beam with unrivaled precision. 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.
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.
Detects delivery errors 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. To 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 damage. No deterioration. No dose rate dependency. No calibration. No maintenance. Simple.
100% active detection area.
Uniquely precise. For every field size. At any location.
The innovative IQM detector design provides 100% active detection area. Every spot of the detector measures radiation, and each beam segment creates a unique and highly specific signal.
The smaller the beam segment, the higher the sensitivity for any possible deviation. Even the smallest stereotactic beam segments are measured with an unrivaled accuracy and specificity. at any off-axis position. IQM is the optimal solution for the verification of SRT and SBRT techniques. Superior precision. No restrictions.
Accuracy by design
Continuous spatial resolution. Unmatched spatial accuracy.
Electrode separation increases linearly from 2mm to 2cm in the leaf motion direction. Continuous spatial resolution provides a new level of measurement accuracy with significantly higher spatial sensitivity than the discrete spatial resolution of conventional 2D or 3D Arrays. No matter how small or large the field size. No matter the field shape. 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. Newly 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. For Quality Assurance that truly impacts patient safety. For Quality Assurance that really matters.
A new level of significance.
Wide dynamic range
IQM provides a wide signal range: from a minimal signal rate of 50 counts per minute, 800 to 1.500 counts/minute for a small VMAT beam segment and 5.000 to 8.000 counts/minute for a step&shoot IMRT beam segment. 230.000 counts/minute for a 10cm x 10cm x6 beam delivering 100 MU at Dmax. 305.000 counts/minute for a 10cm x 10cm x6 beam delivering 100 MU at 10cm depth. More than 4.000.000 counts/min. for a 40cm x 40cm x6 beam delivering 100MU.
Detects any dose change. Immediately.
Measures any dose from 1/10 MU per square cm up to unlimited. Completely independent of dose rate .
The IQM signal varies linearly with applied dose output. Any change in dose output changes the IQM signal in equal proportion. A 2% change in dose output changes the IQM signal by 2%. A 50% change in dose output changes the IQM signal by 50%.
For every energy. For every dose. At every dose rate. All the time.
Covers every field size. No limitations.
The IQM detector design accommodates every field size. From the smallest stereotactic field size at any off-center location up to a 40cm x 40cm field. IQM measures a highly specific signal for every field size.
IQM detects any field size variation in either the X- or Y-direction. IQM shows significant signal variation when the field size changes . Changing the field size from 1cm x 1cm to 2cm x 2cm changes the IQM signal by approximately 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 a 3cm x 3cm field size) creates a 1% signal change. IQM detects parallel shifts of just 1 mm in two opposed leafs. IQM is compatible with any multi leaf collimator design and has already been utilized for picket fence tests.
Sensitive at every field location.
Without exception.
Detects beam position changes with an unrivaled sensitivity in both x- and y-directions. A 1mm change in beam placement creates a 0.5% signal change. IQM detects beam position changes that remain unnoticed with today’s conventional verification tools.
Every time. Without exception.
Highest spatial accuracy.
In its most minimal form.
Unrivaled error sensitivity.
Guaranteed.
