Browsing DICOM images
MIPAV includes a browser that is specifically designed for examining DICOM images. The DICOM browser allows you to view a list of all of the images in a dataset and quickly display each one individually. The browser provides a fast way of locating and selecting specific image slices.
Tip: You can open a DICOM browser at any time after starting MIPAV; and, depending on your computer's memory resources, you can open more than one DICOM browser.
Displaying an image dataset in the DICOM browser
1 Select File > DICOM browser (see Figure 2-1, and Figure 2-2). The Choose Directory dialog box opens, see Figure 2-3.
2 Select the directory in which the DICOM image datasets are stored.
3 Click Open. The DICOM browser (Figure 2-4) appears showing the directory tree in the panel on the upper left of the window.
4 Navigate, if necessary, to the correct subdirectory and select it.
5 Click Parse directory (Figure 2-4). Information appears in the three panels on the right side of the window: patient and study information at the top, dataset information in the middle, and image information at the bottom.
6 Select one of the images listed in the image information panel (Figure 2-5). The image appears in the panel on the left side of the window below the tree structure (Figure 2-6).
You can now continue to browse the images, or you can perform one or more of the following tasks:
- Adjust the image contrast and brightness.
- Open selected images.
- View another image dataset.
- Create a movie from the image dataset.
Opening the DICOM browser and parsing the image directory
</font></div>
The Window and Level sliders that appear in the left bottom panel of the DICOM browser allow you to adjust both the contrast and brightness in the image being displayed. Refer to Figure 2-6.
One of the advantages of using the DICOM browser is that you can quickly identify which images in the dataset you wish to work with. Once you've determined the required images, you can open just the slices you selected.
Once you've opened the DICOM browser, you can quickly switch between working directories. In order to do that:
Set AVI Options dialog box
Subsample image
|
Subsamples each image dimension by a factor of 1, 2, 3, or 4.
|
|
Frame rate

Specifies how many frames, or slices, should appear in 1 second.
| |
OK
|
Applies the parameters that you specified.

|
Choose Type of AVI File dialog box

|
|
M-JPEG quality (0.1 - 1.0)

| |

You can customize the DICOM browser by choosing which columns to display. In order to do that:
DICOM browser interface summary
Menu: File
|
Disregard series numbers - DICOM images use the DICOM Universal Identifier (UID) stored in the DICOM header to name the image files on the local disk. This long string of numbers and dots is designed to be unique among all DICOM images ever created. The Disregard series numbers option, if checked, disregards this number when shows images in MIPAV DICOM browser. Exit - exit the browser.
