1 Instruction Course 7-0//0 Instruction Course 7- High Resolution -D Cone Beam CT (CBCT) Imaging D. Bradley Welling, MD, PhD Professor and Chair Department of Otolaryngology-Head & Neck Surgery The Ohio State University Emeritus professor Ehime University Medical School President of Middle Ear Surgical Center, Takanoko Hospital Matsuyama, Japan Financial Disclosure Dr. Welling consultant Dr. Yanagihara consultant. Principle and features of D-CBCT Imaging D-CBCT image Coronal image Sagittal image D-CBCT technology presents excellent super high resolution X, sagittal, Y, coronal and Z, axial views of complex bony structure in the head and neck such as temporal bone together with realistic volume rendering images from any desired direction. Requiring radiation dose at maximum is less than a half of conventional CT. Axial image Volume rendering image MCT-, Type F7, J. Morita Mfg. Corp. CBCT Image Viewing Features of the CBCT Y Z X Vol R In the standard slice view the Z window shows the axial view, the Y window the coronal view and the X window the sagittal view respectively. Slice planes of each window is indicated by a cursor of a different color - red, blue and green for the axial, coronal and sagittal planes respectively. The slice plane of each respective window can be chosen by dragging each cursor. standard slice view shows a representative CBCT image with standard slice of the left normal ear. When you drag the green cursor right to left, the sagittal image in the X window moves lateral to medial. Drag the red cursor up and down and the axial view in the Z window moves from cranial to caudal. Drag the blue cursor in the X window or the Z window and coronal images move anterior to posterior. One may click a cross point of two cursors and drag the point to the structure you want to see until it appears in the third window. In this way you can pinpoint the image of the structure you want to see. In the fourth lower right window, the volume rendered (Vol R) image is shown. In the window position of the head to obtain Vol R image is indicated automatically in the window. The image of your choice can be printed with an ink jet printer with or without cursor lines.. The CT provides an excellent super high resolution three dimensional view of the temporal bone from any desired direction.. The CT details complex and tiny bony structures with small voxel and narrow slice thickness.. The images are immediately available for review on the monitor of a computer.. The most informative images can be selected by rotating the images in any plane.. Size of imaging area is adjustable to the area of interest.. The apparatus is compact and is easy to set in a small shield room. 7. The patient does not need to make a separate trip for imaging and then another return to the otologist office. 8. Comparing with conventional CT, radiation hazard and risk is reduced. Standard slice view: Along the external ear canal, the internal auditory meatus and the attic.
