Cleanup & Disambiguation needed

The structure should probably be a general article for digital radiography with sections on the history of the technology, the branching points into CR (computed radiography) and later into DR (direct radiography, i.e. cassetteless). Sections on areas of use such as dental, general medical, non-destructive testing etc would follow. This page is presently far too focused on a single aspect, dental, and has no references. As such it doesn't pass the test of verifiability required for an entry.

If there are no objections, I will make a start on the cleanup along these lines. RobinWinsor (talk) 12:31, 26 July 2012 (UTC)

copied?

the digital milestones section appears to be copied straight from a website -(someone wrote sometime)its not all true

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)

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)

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)

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)

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.

Acronym and Abbreviation Creep

Ok, so as a layperson trying to understand the advanced process of "Digital" imaging vs "Analogue" imaging in the X-ray region of radiology, typically when an abbreviation is first encountered, the abbreviation is initially spelled out, so the reader has some sort of idea what is being referred to. In the current (2013-09-18 T 16:20 GMT) version, is the section on industrial usage of X-ray equipment, along with the common use of Human Diagnostic Imaging. Perhaps the same equipment, and or the same procesess are used. However, when first reading through the article, there is no distinction between Industrial usage (IU), and Medical usage(MU). This gives rise to confusion in the reader, as the similar technologies are used , but they have different outcomes.

Radiological examinations - Aerospace

In this article, the term "NDT" is ambiguous, as it was initially part of a portion that may have been removed during a previous edit. Eventually, I am guessing that the term "NDT", is referring to "Non Destructive Testing", however the article as it stands today, does not explain this at all!

What a mess

Ended up on this page because I'm researching uses of selenium, and boy are the pages on this topic a mess. The flat panel detector page only mentioned one of the two types of detector, the history of the technology is not adequately covered, the various types of medical uses are not sufficiently elaborated upon and there is no linking to related issues (the debate surrounding the usefulness of digital mammography seems worth a mention at least, and the use of digital xrays in dentistry has been somewhat revolutionary, but this receives no mention). Unfortunately I don't have the time to fix this myself at the moment, but I'm noting it for now in hope that someone else will get to it or that I'll find time to get back to it.
