SQ Liver - The process

Step 1: CT scan images of liver

• CT or MRI examination modality supported
• 2D images of liver serve as input

Step 2: SQ Liver 3D model of patient based on CT modality

• 3D model reconstructed from the medical scans
• ready to be used by the surgeon in SQ Liver

Step 3: 3D model of liver with all relevant visual information

• SQ Liver consists of two closely integrated sets of tools:
• the 3D viewing tools and
• the liver resection surgery simulation tool.
• Representing the actual patient's situation with parenchyma, vessel systems, biliary system and tumours.

Step 4: Simulation of ultrasound

• Simulation of ultrasound tool is available within SQ Liver as one of the tools.
• Surgeons can compare planned and actual ultrasound views to gain quick insight into the operative procedure scenario.

Step 5: Simulation of usage of surgical tools

• The SQ Liver surgery simulation tools allow surgeons to perform the complete surgery in the virtual environment.
• Performing resections by using dissecting tools for resection lines, cutting vessels and various other tools needed to perform operation.

Step 6: 3D model of liver after resection

• End result is saved and investigated by the surgeons.
• Importantly, volumetric measurement of remaining tissue after the resection as well as comparison with initial values is automatically included.
• There are several measurement options: distances, volumes and other possibilities.

Step 7: Online reports

Online reports are created in SQ Liver, including all relevant operation of the simulated surgery:

• Volumetric measurements pre- and post-surgery.
• Distances between tumours and all relevant systems.
• Calculations of effects of removed parts of the vascular and billiary systems.
