How to convert DICOM images to JPEG
By now, you should have all your images scanned and stored under your file name under E:\people\. All images automatically are stored in DICOM format and are named something like SC100010001(or 2, or 3, and so forth).dcm. Note that these are very BIG files, and that is why they need to be converted to smaller JPEG format.
Opening the image processor:
- Log on to the computer in the usual fashion.
- Click on "Image processing" icon on your desktop
- It’ll give you a directory, under which you can pick your file
- Double click on your file to open it
- All your images should be in there in the .dcm format.
- Click on the image you want to process
Crop and rotate your image:
- This is mostly for a scanned sheet of a CT or a MRI (which has 12 images), upon which you want to pick one specific image to process. Of course, you can always process a chest film, etc., In the same fashion.
- On the DICOM processor controls panel, click "Crop and Rotate."
- A large box with red top line will show up.
- Change the size of the box by clicking on the red line, and while holding the click, drag it bigger or smaller.
- Change the angle of the box by clicking above the red line, and while holding the click, change it in any direction you want.
- Move the box to your desired image by clicking the middle of the box and drag it.
- Once you have the box just where and how you want it, hit "Crop and Rotate" again, and the cropped image will appear.
- If you don’t like what you see, hit "Undo Rotate," and the screen will go back to the entire sheet of images with the red box where you had put it. Make your adjustments, and hit "Crop and Rotate" again.
- If you need to change the windowing of the image, hit "Window" on the control panel, and drag the mouse while holding the left button down.
- Once you hit the "Window" key, the control panel will change.
- Once everything is done, save the image as JPEG by clicking "Save JPEG" on the control panel, and a directory box will come up to allow you to name the image as you wish. MAKE SURE THE CORRECT FOLDER AND CORRESPONDING SUBFILE NAME IS SELECTED before you save. Your folder will NOT be the automatic default folder even though that’s the one you opened the image processor on. All files now will have .jpg as their format. After saving that image, click "UNDO CROP AND ROTATE" and you will return to the full sheet to allow you to chose another image if you so wish. The box size and rotation will remain the same to make this fast and easy.
- You can also save as TIFF by simply clicking the "Save TIFF" button.
- Repeat these steps until all your images are processed.
Don’t Forget to erase the .dcm imags that you no longer need because they each take up to thousands of kilobytes to store, and very soon, the computer will fill up.
