Reviewing the Statistics
The Logging page (Figure 37) displays the statistics in tabular form. Whether or not you chose a type of statistic on the Statistics Options page, the table includes a heading for each type. Blanks cells in the table indicate that you did not choose to obtain that particular type of statistics.
|
|
Each time you calculate the statistics for a VOI the Statistics Generator adds another row of statistics to the table. Note that the first column in the table lists the name of the VOI and, if appropriate, the slice and contour numbers. Also, you can change the width of each of the columns in the table by dragging the line between the columns in the heading.
You can include and review the statistics file in a database or in a spreadsheet program by double-clicking on the file name in Windows Explorer window and, in the Open with dialog box, selecting the application in which you want to open the file.
When the number of rows in the table exceeds the length of the Logging page, scroll bars appear on the right side of the table to allow you to scroll from the beginning or to the end of the table.
If at any time you want to clear, or erase, all of the rows of the table, select Options > Clear log window. The complete table disappears from the Logging page, which is now totally gray.
|
Overwriting statistics files If you previously ran the Statistics Generator and obtained statistics, after you click Calculate a message appears stating that a statistics file already exists. It asks whether to overwrite the file or to cancel the action. |
|
If you not want to overwrite the file, click Cancel. The following warning message appears.
Return to the VOI selection page and choose another file name in the VOI statistic file destination box. Then click Calculate to obtain the new set of statistics. The Statistics Generator calculates the statistics and saves them in the file that you indicated. The statistics appear on the Logging page.
If it's all right to overwrite the file, click Overwrite. The Statistics Generator calculates the statistics and overwrites the previously recorded statistics file.
Tip: If you always want the Statistics Generator to overwrite the file, either select Options > Overwrite file automatically or press Alt O.
Go to the next task: "Reviewing the statistics".
Modifying image resolutions
To modify the image resolution
1 Open an image.
2 Select Image > Attributes > Edit attributes in the MIPAV window. The Image Attributes dialog box opens. See[MIPAV_QuickStart.html#2675737 Figure 38].
3 Click Resolutions. The Resolution page appears.
4 Modify the resolutions.
5 Click Apply.
6 Click OK or Close when complete. The window closes.

Generating graphs (intensity profiles)
MIPAV can generate a graph of the intensity values of a region bound by a VOI. You can then save this graph or intensity profile, to a file for future reference.
Generating new graphs
You can generate an intensity profile for any VOI.
To generate a graph of a VOI
1 Select a VOI in an image window.
2 Use the right mouse button to call the context menu, then select one of the following:
Graph > Boundary Intensity
Graph > Total Intensity
Graph > Average Intensity
Graph > Total Intensity with Threshold
Graph > Average Intensity with Threshold
The chosen Intensity Graph window appears. Each function on the graph represents the intensity levels within each channel. Refer to [MIPAV_QuickStart.html#2896827 Figure 39].
3 Close the graph by either selecting File > Close graph or pressing ctrl x.

Saving graphs to a file
To save a graph
1 Select File > Save graph in the Intensity Graph window or press Ctrl S.
The Save dialog box appears. See [MIPAV_QuickStart.html#2679981 Figure 40].
2 Type a name for the graph in File name.
3 Make sure that Graphs (.plt) appears in Files of type. Refer to [MIPAV_QuickStart.html#2679981 Figure 40].
4 Click Save. MIPAV saves the file under a specified name.
Printing graphs
To print graphs
1 Select File > Print graph in the Intensity Graph window. The Print dialog box appears.
2 In the dialog box, select the printer and adjust the print options if necessary.
3 Click OK to print the graph or image on your default printer.

Saving and printing images
This section explains how to save images to the same format (as when opened) or in a different format. It also shows how to print images. In addition, it explains how to save an image as a TIFF file.
Saving images to the same format
To save an image file in the same format (as when opened)
1 Do one of the following in the MIPAV window:
Click the Save Image icon or use the Ctrl S combination of keys.
Select File > Save Image.
The Save dialog box appears ([MIPAV_QuickStart.html#1045607 Figure 41]).
2 In the dialog box, type the name of the file in File name and click Save.

Note: If you prefer for MIPAV to use the style of Open and Save dialog boxes that are used by the operating system (e.g., Microsoft Windows, Unix, or Apple) on your computer, read the section on [MIPAV_QuickStart.html#1013570 "Using platform-specific Open and Save dialog boxes" on page 74].
Capturing images as TIFF(RGB) files
MIPAV allows you to capture entire images or portions of images as RGB TIFF files.
1 Select File > Capture image to TIFF(RGB) in the MIPAV window. The Capture Screen dialog box opens. See [MIPAV_QuickStart.html#2681571 Figure 42].
2 To capture only a portion of the image:
Select Region, then draw a rectangle with the mouse around the region in the image you want to save. Click OK. The Save dialog box opens. Type the name of the file in File Name, and select the TIFF type of file. Click Save. The region is saved under the specified file name.
3 To capture the entire image:
Select Window, then click OK. The Save dialog box opens. Follow the instructions provided by the dialog box to save the image in TIFF format.
