Standard therapy chamber for scanning systems and for reference dosimetry

The 31010 semiflexible chamber is the ideal compromise between small size for reasonable spatial resolution and large sensitive volume for precise dose measurements.
This makes the 31010 chamber to one of the most commonly used chambers in scanning water phantom systems.

The chamber volume of 0.125 cm³ gives enough signal to use the chamber also for high precision reference dose measurements.

The sensitive volume is approximately spherical resulting in a flat angular response and a uniform spatial resolution along all three axes of a water phantom.
