Recent Advances: Computerized Radiography "Digital X-ray"

Digital X-ray Sensor

Info
• Computerized Radiography is more sufficient then the inferior to traditional Radiography, but in some case the traditional were more accurate.
• Nowadays with better software and instruments, it is possible to gain different objective measurements from the different grades of tooth radioluscent lesions and visualize it on the screen.
• Radiography is very useful for diagnosing Inter proximal caries.

Advantages

• Fast analysis and preparation of large amounts of records for the computer.
• High sensitivity and Accuracy (up to 1024 grey levels) for better peripheral structure definition.
• Computers give the ability to manipulate the images digitally.
• No processing.
• Low exposure time.

Disadvantages

• When the digital images are enhanced on the monitor it is shown with a lower quality compared to the original images.
• Area of interest is still mostly subjective decision depending on the observer’s judgments.
• Possible errors during transfer of data.
• Very expensive.
• The digital result usefulness is limited by measurement errors “which is because its based on subjective decisions and there isn’t error elimination by the computer”.
