OCTAVIUS® Detector 1600 MR -
Unique Detector Properties
- Advancement of well-established OCTAVIUS® Detector 1000 SRS
with > 50% more chambers - 1521 liquid-filled ionization chambers with an active volume
of 2.5 x 2.5 x 0.5 mm³ (0.003 cm³) - Enlarged active detector area with 15 x 15 cm²
- 729 ionization chambers in enlarged high-resolution inner area
of 6.5 x 6.5 cm² - Spatial resolution 2.5 mm in inner area
- For filmless patient plan verification and machine specific QA
- Excellent error detection for all stereotactic treatment plans
Optimal size for multi target SRS treatments
Stereotactic treatments require high radiological and, most importantly, spatial precision which should be checked for each patient individually.
Due to its high spatial resolution (2.5 mm) and its large detector area of 15 x 15 cm² OCTAVIUS 1600 MR allows patient specific QA of SRS treatments.
Commissioning of SRS/SBRT techniques
PTW OCTAVIUS Detectors have proven to be accurate tools for planar dose measurements.
Especially for radiotherapy departments implementing SRS/SBRT delivery techniques into their clinical practice, OCTAVIUS 1600 MR can support and facilitate the commissioning process.
