[edit] copied?

the digital milestones section appears to be copied straight from a website -(someone wrote sometime)

[edit] merger

if articles are to be kept separate, than they should at least refer to each other. I admit that computed radiology appears to be non digital radiography in the sense that the radiographic image is not directly taken in by digital sensors but through an intermediate form of radiographic film Bouncingmolar 01:23, 14 March 2007 (UTC)

Digital radiography and computed radiography are not the same thing. As bouncingmolar said, DR attains and stores the image via digital sensors. CR does not use film but does use a cassette which is used just like an ordinary film cassette, which stores the image until it is loaded into the computer. dreadpirate 02:06, 4 April 2007 (UTC)(dreadp1rate, april 2, 2007)

Projection Radiography (not radiology) is really the parent topic for Film Radiography, Computed Radiography, and Digital Radiography. While the three are similar in the types of diagnostic information that they provide, they are quite distinct in how they go about providing it. The different types of radiography should refer to each other, but it is important to note that they are different stages of technological advancement.

CR and DR should not be merged, but should contain links each to the other.

Note that Film, Computed, or Digital Radiography aren't bounded solely to projection radiography. They are also applicable at least in tomographic imaging (orthopantomography or linear tomography in dental use, for example). 213.138.128.44 12:11, 16 August 2007 (UTC)

[edit] peculiar usage

Only a specialist will understand that the terms Digital Radiography and Computed Radiography have been hijacked by history (if the above is correct) to have very limited meanings, instead of the more general meanings a general technical reader would expect. So, the articles need to be carefully labeled at the outset, and readers appropriately referred to the related and more general articles.

As an outsider, in the long run it would seem like all three 2D tech articles should be merged, if the technologies all produce essentially the same images, using xrays. Or maybe, they should all sort of be stubs, just addressing the detailed history and differences, and all general-interest readers forcefully shunted to the main Projection Radiography article? -69.87.200.227 (talk) 02:40, 5 February 2008 (UTC)

[edit] distorted perspective

this article has probably been written by a dentist as the perspective is 100% distorted in direction of digital dental radiography --134.100.5.65 (talk) 20:49, 24 February 2008 (UTC)

[edit] Where is the rest?

I agree, there is a total lack of any other medical useage of digital radiography in this article.
As a field service engineer, I work on many different types (no dental though) of digital x-ray systems.
Ranging from a simple portable units with a Cannon imaging system to mammography units, urology units, 

even up to bi-plane heart cath labs. No mention of the Image Intinsifier or the newer flat panels at all
which is what brought x-ray into the truly digital age.

As far as tomo and CT, many of the "2-D" systems are now capable of 3-D reconstructions. Most notably portable

flouro c-arms and c-arm styled cath labs. 

I guess someone should add to the article? —Preceding unsigned comment added by Robtheengineer (talk • contribs) 05:16, 18 March 2008 (UTC)

[edit] CR and DR mixed up

I would argue that the author has confused the terms Digital Imaging, Computed Radiography and Digital Radiography. CR normally refers to the use of a Photostimulable Phosphor (PSP) plate onto which an exposure is made. The PSP plate must then be scanned and 'read' (the Computed Radiography correctly describes this). Digital Radiography, or Direct Digital Radiography usually refers to image capure onto an amorphous silicone or selenium plate, the data being passed electronically to the processing computer. Digital Imaging refers to both of these as well as other modalities such as CT, gamma cameras etc. Confusion arises when the term Digital Radiography is used instead of Digital Imaging.
