Just received a much anticipated phantom today: Phantom Lab's Liqui-phil organ phantom. I gotta say, it's pretty schweet too. Purchased with my first grant, I was expecting to get it a month ago. It's here now, and I'm really looking forward to using it.
At first glance it looks rather daunting. You're confronted with a phantom with lots of small and large bits. There are 6 fillable organ chambers (liver, 2 kidneys, stomach, spleen, pancreas) each of which can be positioned anywhere you want in the main chamber. There are also a number of fillable spherical and ovoid chambers that can be inserted into the main chamber, or into the organ chambers to simulate hot or cold spots.
This is going to be so much fun to play with.
Next step: Learn how to fill and insert all the chambers without making a radioactive mess out of myself.
