Accessibility Name for Image in a TreeView

Hi,
I'm using a TreeView with an ImageList, and have some nodes with ImageIndex inside the TreeView
I want my screen reader (Jaws) to read an alternate text for those Images
but I couldn't find an AccessibilityName property for those Node or Images.
Is there a way the I can set the AccessibilityName for the node combine with an alternate text for his Image?

Thanks
