How to get all the elements in WPF.MapControl in a rectangle without looping all elements

Hi,

I have a Wpf.MapControl. I have images on the Map View. I need to get the list of all the Images that fall in a specified rectangle that the user can draw anywhere on the map. All these images are present in a single map layer. Is there any way i can get the elements in the rectangle without looping all the images in the layer?
