Why Cas-One
for surgeons?

Why CAS-One navigation?

Surgical resection is usually the first treatment considered for primary liver cancer and liver metastases.  But for even the most skilled surgeon, navigating the complex structures of this vital organ in the face of small, multiple or vanishing lesions can be a challenge.  Conventional ultrasound provides real-time guidance, but does not contain the same level of 3D information and anatomical details as pre-operative imaging. At CAScination, we believe that by providing advanced navigation and planning systems with state-of-the art 3D and augmented reality visualisation technology, we can help you to achieve the best possible outcome for your patient.  Our CAS-One Surgery technology is available for open surgery, laparoscopy or ablation procedures, and provides you with a clear view of your target lesion or lesions throughout the procedure, helping you to overcome the challenges of liver surgery.

  • Improved visibility with 3D visualisation of hard-to-see vascular structures and lesions
  • Combines fast, precise tumor targeting with the avoidance of critical structures
  • Simple-to-use - seamless integration with ultrasound technology means no switching between systems
  • Imaging of invisible structures with Ubersound® augmented reality may result in better surgical outcomes
  • May provide an option for patients previously considered ‘untreatable’ with resection or non-guided ablation


Invisible lesions, complex vascular structures and hotspots can be difficult to navigate during surgical resection or ablation procedures. Successful outcomes rely on the surgeon’s ability to ensure that the target lesion is reached and removed in its entirely, but with only conventional ultrasound as guidance, this can be like ‘driving in the dark’.


By combining the latest 3D and augmented imaging techniques with real-time intra-operative ultrasound imaging, you will be able to view features that would not be visible with ultrasound alone, helping to make


Modern chemotherapy regimens often result in complete radiologic remission in the treatment of liver metastases (Huber et al, 2015). However, these “vanished liver metastases” often contain vital tumour cells which need to be resected. Identification of the lesion can be challenging using conventional technology.


CAS-One Surgery guides you directly to each individual lesion, precisely and quickly, so that tumours can be ablated using minimally invasive techniques. Furthermore, our integrated ablation volume predictor allows you to predict the optimal amount of energy that should be delivered directly to the tumour.


Operating rooms are limited in size, and clinicians need room to manoeuvre. New technologies can take up valuable space, and if new technologies don’t slip seamlessly into the existing set-up, they can even introduce complexity to procedures, rather than simplifying them.


We worked closely with clinicians to ensure that CAS-One Surgery integrates seamlessly into your existing set-up, taking up minimal space. CAS-One provides a direct link between image guidance systems and state-of-the art sonography, so there is no need to switch between monitors and systems during the intervention.
