The Vienna Ring CT/MR Applicator is based on the CT/MR Ring Applicator enhanced with the addition of nine guide holes in the ring tube. These guide holes allow placement of interstitial titanium needles using the ring tube as a needle template. The addition of interstitial needles makes it possible to achieve asymmetric alteration of the dose distribution. The ring is used as a template for interstitial needle placement while maintaining the treatment channel of the ring tube. The needles are inserted perpendicular to the ring and are parallel to the tandem. The applicator is fully CT/MR compatible. Its design uses composite fiber tubing to eliminate distortion on CT or MR imaging. This enables conformal treatment planning with the use of transversal slices.


Applicable body sites:

Major Qualities and Benefits

• Applicator design optimized to perform 2D as well as 3D cervical Brachytherapy treatments.
• Extended tumor stages can be treated. This will result in a higher patient throughput, resulting in a positive return on investment.
• Flexible solution to achieve an optimal conformal cervix and parametria (local advanced cancer) dose coverage
• Vienna Ring can also be used as a standard ring applicator and has a fixed geometry
• Pre-bent titanium needles, which are fully CT/MR compatible and that allow MR image guidance.
• Different ring dimensions for customized patient treatments
• Smit Sleeves CT/MR are available for easy cervical insertion of the applicator; see ‘Accessories’.
