Important Benefits of Quality Ablation with CAS-One IR
Enhanced Reliability and Accuracy with CT/MRI Planning and Navigation
- Plan and navigate treatment intuitively in 2D and 3D
- Treat 'invisible lesions' through MRI fusion1
- Visualize ablation volumes of >75 MW, RFA, Cryo, IRE devices2
- Improve accuracy through mechanical needle guidance3,4
- Achieve low repositioning rates (1%)5
Treating more Patients with Challenging Cases
- Maintain confidence near structures of risk with ablation planning and navigated needle placement
- Treat multiple and/or large tumours (> 3cm) with overlapping ablation zones6,7
- Increase ease of complex cases with angulation, long distance to target7
- Reduce intervention time by 57% and variability by 67% enabling treatment of more patients4
Consistently Low Complications,
and Reduced Recurrence Rates
- Reduce recurrence rates8 (9% vs. 14-30%) with safe and reliable ablations
- Achieve low overall complication rates (6%)7
- Add consistency to treatment success with ablation validation10
- Reduce bleeding and tumour seeding5 with low needle repositioning rate (1%)

Quality Ablation reduces Treatment Time
Standardising procedure planning accelerates treatment by reducing needle placement time and need to repositioning
Conventional IRE
Stereotactic IRE CAS-One IR
Preparation Planning Needle Placement
Reduce intervention time by 57% and variability by 67% enabling treatment of more patients.4
Reduction of Radiation Dose
Standardised Quality Ablation workflow leads to lower exposure to radiation dose
The more scans you do, the higher the radiation dose both for patients and physicians. With lesions easily accessible, this is not a problem. But the more advanced treatments you're doing with double angulated trajectories or multiple needles the complexity increases. The same is true for the radiation dose, because complex treatments usually require more scans. The workflow of Quality Ablation standardises treatment time also in complex cases. The result is a significant reduction in radiation dose.
The Quality Ablation experience
This 13-minute video, filmed during a real intervention, guides you through the six steps of each Quality Ablation procedure: Imaging, planning, navigation, validation, treatment and treatment verification. It provides in depth insights on why standardisation is key to obtaining improved outcomes for patients.

Success Stories
Learn how the start of a Quality Ablation program helps to expand treatment options for tumour patients.
„Thanks to the increased safety during the intervention, CAS-ONE IR can be used to treat several lesions within one procedure.“
„CAS-One IR has helped us to be more precise in our work. And with ablations, great precision leads to better results“
