Digital Radiography Systems

The Digital Advantage – What Dental Team Members Should Know

Digital dental radiography decreases overall costs and potential human errors because it doesn’t require film and, therefore, avoids the costs of chemical processing and processing errors. It also

eliminates errors due to film handling and decreases the need for retakes, which increases radiation exposure. Besides cost-cutting measures, digital dental radiography images also provide enhanced image quality. Through post-processing measures, the clinician can achieve higher quality images by utilizing contrast, brightness, zoom, sharpening, smoothing, and color settings. With these tools at the operator’s fingertips, correct exposure can be achieved after x-ray exposure, eliminating the need for retakes and subsequent radiation exposure. These enhanced images also offer clinicians improved diagnostic quality. Images are captured more objectively than with traditional film. The automated image analysis allows the clinician to see the image almost instantly, providing immediate attention. Through the use of the imaging tools, images can more easily be interpreted. These improvements in diagnostic quality help clinicians determine the most appropriate treatments.

Maximizing Clarity of Digital Dental Radiography Images

Clear digital radiography images are essential for accurate clinical diagnoses. The advanced clarity found in digital dental radiography images has demonstrated significant diagnostic DEXIS Platinum Sensor Closeupadvantages.12 With clear images, clinicians are provided with the most reliable information and detail. Common mistakes seen in conventional film can be avoided through manipulation of the  image post radiation. Patient care also improves with the use of clear digital dental radiography images. Besides receiving a more definitive diagnosis, patients can now be more involved in treatment planning. Conventional scans, with their small size and lack of clarity, often deny patients the ability to see for themselves what clinicians are sharing. Clearer images with higher resolutions—the result of digital radiography— make it easier for patients to understand their diagnosis and treatment plan, and patients become more invested in their treatments. The proper equipment is vital to ensure all benefits of digital radiography are reaped. Previous studies have found that indirect systems that digitize conventional radiographs using high-grade scanners or digital cameras do not offer diagnostic quality images. Direct digital systems offer easy, high resolution, and clear images. Most digital systems provide high-resolution images that allow for magnification without pixilation.

However, to ensure the highest quality images while providing an excellent patient experience, exceptional technology is a must. Such a system must complement current practice technologies, integrating seamlessly into the workflow while remaining easy to use. While many digital dental radiography systems meet some of these standards, the Dexis system provides unparalleled quality images while improving the patient’s experience.

Dexis Digital Radiology System

The Dexis system offers all of the benefits of direct digital dental radiography. It is a direct-USB digital x-ray solution with a high performance single CMOS sensor that connects directly to the computer. The single sensor can take vertical and horizontal bitewings and all periapicals, eliminating the inconveniences and high cost of using multiple sensors. Unlike many direct digital systems, Dexis uses a fully integrated direct USB connectivity, replacing the need for a separate adaptor or a docking station. The USB also has increased durability due to gold plating on the connector. The sensor has a wise angle cable exit to help patients better tolerate the procedure. It provides flexibility in the cable to reduce stress and increase

reliability. The sensor also has four beveled corners and a casing that is smooth and rounded. This ensures that there are no sharp edges, while the smaller angled dome is helpful for precise posterior placement. Finally, affixed to the interior wall of the rear housing is a protective shield to guard the patient from X-ray back scattering. The sensor was designed with patient, technician, and clinician in mind. The Dexis system easily integrates into any dental practice. The images are automatically synchronized with patient records, enabling easy access to the patient’s images and chart. Within the charting program, preview thumbnails and clinically relevant full-screen images are available. The full-screen images are viewed by simply clicking on the thumbnail image visible in the charting program. It can also run in the background, without the window being displayed. All these features ensure the Dexis system works seamlessly with dental practice software, as well as the dental team members work style. The ability to produce high quality images is an important factor when selecting a digital dental radiography system. Dexis uses Pure Image technology to create clear images. The x-ray beam is converted into visible light through a premium quality cesium iodide scintillator, which guides the X-ray through its microcolumnar structures. Fiber optics then transmit the light to the CMOS sensor surface, allowing for high signal-to-noise ratio that results in clean images with almost no visual noise. The high resolution CMOS sensor maximizes the active area at the pixel level, bringing out the smallest details. The enhanced quantum efficiency of the sensor increases reception and efficiency when capturing images across a dynamic range of radiation settings. Subtle variations in densities can be seen through the 14-bit analog-to-digital converter that generates 16,000 shades of gray. Generated images are 2.2 megapixels and can be displayed at ultra-large sizes. The high quality of Dexis system images can be assessed when the image is zoomed in and there is no loss of quality or pixilation.
