OCTAVIUS Detector 1000 SRS Array

Detector matrix with 977 ionization chambers for patient plan verification and quality control of small fields

The OCTAVIUS Detector 1000SRS is the first liquid-filled 2D ionization chamber array. The very small detector size of only 2.3 mm x 2.3 mm x 0.5 mm makes this array ideal suited for dosimetry of small fields.

Target application is patient plan verification in stereotactic radio surgery and quality assurance of small fields. In the inner area of 5.5 cm x 5.5 cm the detector distance is 2.5 mm center-to-center, in the

outer area of 11 cm x 11 cm the detector distance is 5 mm center-to-center. On the main axes the detector distance is 2.5 mm, on the diagonals 3.5 mm. The excellent surface coverage of the liquid-filled

ionization chambers ensures a virtually complete field coverage which otherwise can be optained by film only. The OCTAVIUS Detector 1000SRS can be used in a slab phantom or the OCTAVIUS Rotation Unit. It is compatible with the PTW software.
