Objectives: This study evaluated the impact of variations in anteroposterior and lateral tilts of patients head on radiation-weighted doses to organs/tissues and effective doses using 3 different cone beam computed tomography (CBCT) machines.
Methods: An anthropomorphic phantom was used to estimate radiation doses in 3 CBCT machines (OP300, Eagle X 3D, and Eagle Edge). Thermoluminescent dosimeters were placed in regions corresponding to pre-stablished organ/tissues.
Article Synopsis
- The study aimed to assess how high-density objects affect the measurement of another high-density object in cone-beam CT (CBCT) scans.
- Cylinders made from cobalt-chromium, titanium, and zirconium were tested in various combinations within a dummy model to observe changes in their measured volume using two different CBCT systems.
- Results showed that the presence and arrangement of these high-density materials significantly influenced the volume measurements, with effects varying based on material type and the specific CBCT system used.
