![]() ![]() And from there, it's only one more step to making a 3-D model. If you could put together a flip book made from a series of X-ray “slices” of the same subject, taken at slightly different angles, you would be able to create an “animation” of the X-rays. When you rapidly page through it, you may see (for example) an animated cartoon or a still subject from different perspectives. Now imagine a “flip book” - the kind of small book made up of a series of pictures, each slightly different. But conventional X-rays are limited: Like a still-life picture, they show only one perspective on the scene. ![]() The difference is that energetic X-rays can penetrate bone and soft tissue, and reveal its hidden structure by their varying degrees of absorption in other words, they form a grayscale picture of what's underneath the surface. Just as light makes an image on photographic film (or a digital camera sensor), X-rays can also form an image. X-rays, like visible light, are a form of energy on the electromagnetic spectrum. But, as with any diagnostic tool that uses radiation, the medical benefits offered must be weighed against the (small) potential risks of the procedure. The detailed diagnostic images that CBCT provides have made it an essential tool in many dental specialties. For the patient, it can reduce the need for invasive procedures, shorten treatment time and offer the chance for a better outcome. For the dentist, it offers the ability to visualize intricate structures inside the mouth, such as root canals, nerves and sinuses (air-filled spaces) in the jaw - in three dimensions - without surgery. But it's a quantum leap forward in technology and diagnostic precision. Today, Cone Beam Computed Tomography (CBCT) promises to change the way many dental problems are diagnosed and treated.Ĭone Beam CT has some similarities with conventional X-rays, and also with the standard CT scans you would get in a hospital setting. At the dawn of the 21st century, a revolutionary new technology has entered the diagnostic arena. graduated from Lawrenceville (N.J.)
