Clinical evaluation of patient misalignment during CT scans for computer assisted implantology — a new approach for compensation

Computer assisted implantology relies on good CT data. Therefore a strict protocol for acquiring the CT scan has to be adhered to. Most errors are introduced by misalignment and movement of the patient during scanning. We introduce a new method in terms of software algorithms and of clinical protocol changes, which allows for an optimal patient positioning to reduce movement artefacts and for compensating patient positioning misalignments.
