Purpose: To improve the image quality of small low contrast objects and overall image quality from Cone Beam Computed Tomography using a new entropy technique. Materials and Methods: Cone Beam CT(CBCT)images were acquired using the Catphan phantom in an Acuity Simulator. The images were acquired at 125 kVp, 80mA with 2.5 mm slice thickness. All the images were acquired in a full fan configuration. A new criterion for image enhancement was developed based on entropy behavior. For some of the… CONTINUE READING
