How to read a DICOM dataset ?

After successfully loading the DICOM files (see “How to upload a DICOM dataset ?”, the DICOM images are directly accessible through the database. A doubleclick on a row in the database allows the user to view the DICOM dataset corresponding to this row. The DICOM images are arranged according to the DICOMDIR file's organisation, and each DICOM image belongs to a specific series. The series are organized in a tree. This tree is displayed in the left window (“DICOMDIR series”), as shown below.

To view the DICOM images, the user has just to drag and drop the selected series in the viewing window of his choice.

When two series are displayed, JIMBO computes the line of intersection between the two DICOM images and represent it as a yellow line, as shown above.

By default, two windows are drawn. The user can change the number of windows from 1 to up to 9.bSetWindows.png

Browsing a series of DICOM images

The user can browse a series of DICOM images either by using the mouse wheel or by using the arrow keys of the keyboard.

  1. select the view window in which the DICOM image serie has been uploaded.
  2. press the arrow-key up / down : the user has access to the next or the previous image
  3. turn the wheel forward or backward : the user has access to the next or the previous image.

A fast forward or backward displacement in the image series is possible either when the user press the mouse wheel and move the mouse toward the bottom or the top, or when the user press the page-up or page down keys (displacement of five DICOM images forward or backward).  

Image processing tools

Changing the contrast and the brightness of the image

For monochrome images : enables contrast and brightness enhancement. For 16 bits images, it uses a non-linear image processing algorithm, according to the DICOM standard (Check the part 3 of the standard C.11 for more detailed information).

It has no effect on RGB images.

Changing the transparency of the image

Add transparency to the image.

Adding a color table to a grayscale image

Add a color table to grayscale images. Two color tables are available :

For example, these color tables are intended to be used with TEP-TDM DICOM images which requires a conversion from grayscale images to color images (see below).
