WPF: More efficient way of displaying quickly-changing images?

Question

I'm using the Image control to display an 8-bit grayscale image that I process myself on a background thread. Once the image is processed, I set the Image.BitmapSource property to point to a new bitmap I create via BitmapSource.Create(). This is all well and good - until I have to rapidly reprocess the image and throw it back on screen.

The project that I'm working on requires that I be able to reprocess and refresh the image at ~15-20 FPS. I can get images to the UI that fast - that isn't the problem. The problem is the display flickers in an unpleasant way. I'd like to avoid this.

Pre-WPF versions of my project relied on GDI to do this and were able to handle it without the flickering. I'd prefer to not use GDI (or GDI+).

Is there a more efficient WPF-way of doing this?
