A 32-year-old male presents to the ED after being shot.  He has an entrance wound noted at the anterior axillary line near the lower costal margin.  An upright chest radiograph reveals no intrathoracic trauma.  The bullet's location is not seen on the chest radiograph.  The patient's vital signs are stable.  You are asked by the trauma surgeon to perform a FAST exam to see if the patient has hemoperitoneum in Morison's pouch.
