What is a Maximum Intensity Projection (MIP) image?

Blood vessels in MR and CT Angiography data sets are best viewed as Maximum Intensity Projection (MIP) images. This method of reformation takes the brightest pixels in the image volume and projects them into the final MIP image. Since blood usually has a higher pixel intensity than other structures in the background, the blood vessels are displayed brighter than the background.

As you manipulate and view images, you may want to document or save a specific view of an image.  You can take a Snapshot in any view port with these simple steps.  First, right mouse click on the image to show the menu.  Select View>Snapshot from the menu and the Save Snapshot dialog will be displayed.  From here, you need to locate and open a specific folder in which to save the image.  You can create a new folder with a specific patient’s name (ex. Smith, John) or a new folder such as “Presentation Snapshots” or “Show Images”.  In the File name box, enter the desired file name for example, “Left kidney measurement”.  In the Save as type box, select the type of file you would like to save.  You can save images as Window Bitmap Files (*.bmp), GIF (*.gif), JPEG (*.jpg), PNG (*.png), or TIFF (*.tif) with the default being JPEG.  Click the Save button to complete the process.  FiatLux Visualize can only save images to a non-DICOM file. Each snapshot will be labeled “Not for Diagnostic Use”.  The Snapshot is available in all viewing formats except Original/Source Images Study View.

Maximum Intensity Projection (MIP) images are used to view blood vessels in CT or MR data sets.  This method of reformation takes the brightest pixels in the image to display.  To create a MIP image, right mouse click in the Volume view port to show the menu.  Select Appearance>MIP from the menu to generate a MIP view. (Please note that the menu item is now changed to Undo MIP.)  You can click Appearance>Undo MIP to restore the image to Volume rendering.

This is a MIP image from a MR Angiogram of the Circle of Willis in the brain. A large aneurysm is visible on the right side of the Circle of Willis.

Once the MIP image has been created, you can interactively rotate and view the image from any angle. This is useful in such cases to help determine the origin and location of the aneurysm.
