One example of how 3D image processing techniques play out in a real-world situation involves Simpleware software users 360 Knee Systems, who design patient-specific knee replacement solutions. Working with orthopedic surgeons to design and inform preoperative plans that solve the problems associated with the different challenges of individual patients, the workflow is as follows:
1. CT scans are obtained of the hips, legs, and ankle bones of patients
2. Data is imported to Simpleware ScanIP for 3D image processing of the anatomy, and to position CAD implants within the patient geometries
3. Scripting is used to more easily perform repeatable tasks such as optimizing segmentation and landmarking scanned bones, with the latter being used to create axes and references for simulations
4. The final 3D models created in Simpleware ScanIP are used to create patient-specific guides for surgeons by tailoring shape and fit to a unique patient, including where cuts need to be made, and the optimal placement of implants
5. 3D printed models are also created from the Simpleware files to make it easier for surgeons to visualize cutting positions for different parts of the bone and implant.
