Selecting an ellipse as a region of interest (ROI)

I used imellipse to select an ellipse as my region of interest (ROI). The issue is that the ellipse I want to select is of around 45 degrees, and, when I use imellipse, it seems it is 90 degrees either horizontally or vertically.

How can I change the orientation of the ellipse?

Thanks.

Image Analyst should be getting the credit for the answer but here http://www.mathworks.com/matlabcentral/answers/76788-how-to-rotate-imellipse he gives an example of rotating an ellipse outside of using imellipse.

There is no way to interactively specify a tilted ellipse. Best way I can think of is to draw the two axes (major and minor) interactively with two calls to imline().
