"Good morning class, today we shall be looking at medical imaging, and how it is used for monitoring the health of a pregnant woman" says Miss Nisouman.
"Ultrasound is one such imaging method, using waves of high frequency sound to look inside the human body"
Sets of ultrasound imaging equipment are distributed amongst the class.
"The sound waves reflect off the different layers of tissue, which allows an image to be built up"
"Now, if you've quite finished ultrasounding each other, we'll have a look at the slaves you're using for your human breeding lessons"
The class put the ultrasound equipment down, until the pregnant slaves arrive.
Louella's group examines Hazli with the ultrasound, and peer at the images on the device.
"I don't know how doctors make sense of these images, it's all wibbly", says Sehrazah.
"Try putting more of that gloop on"
"that's better, still a bit wibbly though"
"look, that line looks like a head, omg so does that line"
"Miss Nisouman?"
"What is it, Louella?"
"we don't understand this image?"
Miss Nisouman has a look. "Oh, well that's interesting."
"What is it, miss?"
"It seems Hazli here is carrying twins."
"omg, awesome!"
After ultrasound imaging, the class look at other imaging techniques.
