CR (Computed Radiography)
Good image quality
Multiple steps to image
DR (Direct Radiography)
Better image quality
DR is represented by two major technologies:
Flat-panel and CCD (Charge Coupled Device)
Computed radiography systems replace the film,
intensifying screen and cassette used in traditional
radiography systems with an imaging plate.
Additionally, the film processor used in conventional
radiography is replaced with a digital imaging reader.
involved in used CR technology are:
Imaging plate is placed in the bucky tray.
Exposure is made.
Plate is removed from bucky tray and placed
in imaging reader.
Image is captured and stored on PC.
Imaging plate is erased inside the reader
and ready to use again.
Direct radiography is where the conventional
radiographic cassette and film are replaced with
a digital imaging sensor.
involved in obtaining a DR image are:
The imaging sensor is exposed by x-rays.
An image appears on the computer screen.
Your image is immediately created.
medicine, this advantage is enormous.
Imagine if you
could look at a monitor to see if you needed to repeat
a radiograph without letting the animal move!
