Three bovine tibial specimens are prepared with defects for scanning.
3D scanning metrology has been successfully implemented in many industries including space engineering, civil engineering, automotive, archaeology and entertainment. Applications of 3D technologies in orthopaedics are likewise increasing; use of 3D technology has been described for preoperative visualization and planning in trauma and elective orthopaedic surgery, manufacture of customized surgical tools, customized 3D printed implants, as well as production of orthoses and prosthetics. However majority of the described applications are based on preoperative CT and MRI scans and have limited intraoperative use.
The objective of this study conducted by Dr. Shahriar Seddigh of Dalhousie University is to compare volume accuracy of 3D scanner to microCT scanner for measurement of bone defects in animal tibial bone models.
The details below is a sample volume comparison between the two methods for Specimen:
Trial 1: 113.818 (Computed Tomography) ; 115.854 (Structured Light)
Trial 2: 122.03 (Computed Tomography) ; 121.155 (Structured Light)
Structured Light 3D scanners can accurately measure volume of bone defects in animal tibial models as compared with microCT scanners.
