The blobs we love to see

I've been searching online for a good picture that describes what we go through during ultrasounds and development throughout each cycle, and I think this is a good one to share.  This is what a follicle ultrasound looks like.

Here’s a shot of the screen from a camera phone. The black cluster in the middle is four follicles from the left ovary. The tech measures across each follicle by clicking a point on both sides and drawing a line through the center. Then, as she moves the wand slightly, more follicles appear. It’s impossible to imagine how she manages to keep track of them all — just a bunch of blobs floating around like clouds.
