Opening cdrzip

Visit to the dentist

6th March 2008 - 15:41 - bob

Just spent the best part of a hundred quid on a check-up visit to the dentist and a few x-rays.

Thankfully my teeth are mostly all fine, although they did notice some gum recession (that isn't a great thing apparently)

Anyway, as the xrays are all digital (with the coolest little xray camera that they put in your mouth to take the picture) and, of course, I asked if I could have a copy.

Usually I would object to personal information being passed, unencrypted over the internet, but I don't think there was anything too sensitive the file.

Anyway the file that he sent me was called :

34BD93C9.CDRZIP

(one or two characters of the filename changed to protect the guilty)

Mmmmm... ZIP, I wonder if that's just simply compressed? 7-Zip does the job nicely (right-click, 'extract to')

We are left with a folder containing :

1,822 DICOMDIR 578,914 Image10 578,914 Image11 5,594 ViewSet1 4 File(s) 1,165,244 bytes

Of course, I start with the images. Thankfully, using GIMP (you can download the Windows version of GIMP from gimp-win.sourceforge.net, and specifying the 'open...' type as DICOM (although you will need to view 'all files' as the image files don't have extensions) and you're left with a nice pretty picture. I just saved them as JPEG and the results are here :

2008 teeth image10 - Click to enlarge.
Click to enlarge.

2008 teeth image11 - Click to enlarge.
Click to enlarge.

The other two files are a binary mush, with waaaay too much personal info to post here, but I'm sure that the DICOM website and their interesting looking ftp site may be of use.

Hi!
Thank you for this very useful instructions on opening DICOM images. -
Needed to open some images from my dentist and the DICOM programs are very difficult to use. Gimp works. -

Thank you!

I want to thank you too for your most helpful instructions. GIMP really does the trick, together with your file opening instructions. You really saved me.

I was having the same troubles. Thanks for laying it out in a readily assessable way!

darn you clever, clever Brits. You've given us a language, economic system, body of law (you probably want to disavow our behavior) and now you also clue us into how to break into CRDzips. Thank you very, very much for the well layed out how to (and thanks for the language, economy and laws also) so that I can actually make use of the 200 x-rays that my dentist thought that I wouldn't be able to break into.

Hi. Thanks for this. As an orthodontist, I occasionally get e-mails with this extension and till you posted this, have had difficulty opening them. I'd like to offer a few more steps to make the images look like normal x-rays. The images shown above are actually inverted. Here is my protocol

Use 7-Zip to open the file. Then, right click on each image, opening the file with gimp-2.6. This will bring up an inverted image. To view it like a normal x-ray, you need to go through a few more steps.

Go to the Colors tab and select Invert.

Then, click on File, Save As, give it a name that you would like, Browse to the folder that you would like to save it, choose JPEG as the Select File Type, and hit Save. This will bring you to a window with a slider bar. Slide the Quality up to 100, click Show preview in image window, and Save.
