Digital Radiography Has Improved Upon Conventional Radiography And Made The Job Easier

Industrial radiography is used extensively as a nondestructive testing method for a variety of applications. When we talk about conventional radiography, silver halide film is used for creating an exposure. But progress in technology has enabled us to do all of it digitally. Modern devices are used to create a radiograph that develops an image composed of pixels on a computer screen. We no longer have to depend on film to create a radiograph.

It is important to note that differences exist in digital radiography as there types within digital radiography. Let’s take a look at them.

Digital Radiography Types

• Direct Radiography - In this form of digital radiography, a plate is employed to capture the image and is sent instantly to the computer. There are no steps involved in the middle of the process to capture the radiograph. With this method, you can expect high-resolution images. You also have the option of coming up with real-time results but this capability is dependent on the device being used
• Film Digitization - This method makes use of both conventional and digital radiography. First, a radiograph is developed with the help of an X-ray film. Then to analyze and archive the film on a computer, the film is laid in a reader that reads and digitizes the exposure
• Computed Radiography - In this method, X-ray film is not used. In its place, an imaging plate is employed on which the image is kept as a photosensitive storage phosphor. After this, a digitizer is used which scans the plate with a laser beam and releases the image information as visible light. At last, this light is changed over into a digital image

You can learn digital radiography testing at a reputed NDT training school such as the NDT Consultancy Services. There are advantages of using digital radiography over conventional radiography. Let’s take a look at those advantages.

• In digital radiography, you do not need to use dangerous chemicals or a darkroom, things which conventional radiography calls for
• With digital radiography, you get the shorter exposure time
• Convention radiography develops images that lack dynamic range. But those produced with digital radiography makes it possible for you to use many exposures to create a high contrast image
• You do not have to worry about a digital radiograph degrading in quality when emailing, enhancing, and copying it
• There is no trouble of deterioration with digital images
• No requirement of temperature controls for images produced using digital radiography
• One of the amazing advantages of digital radiography is that a technician can easily zoom in to a digital radiograph, place different radiographs side by side, and analyze them

At a certified NDT training center, you can learn the methods of digital radiography and use them in the field. If you’re interested in learning digital radiography testing methods, get in touch with NDT Consultancy Services as it is a reputed NDT training school in Texas.
