Ultrasound Monitoring of Abdominal Soft Tissue

This research study is being done to collect data and analyze the motion of soft tissue in the abdomen (liver, pancreas, stomach and intestines) of people who have pancreatic and liver cancer as well as healthy volunteers. During the study researchers will look at the movement of organs in the abdomen that naturally occurs with breathing and with a bowel movement. This study will examine the differences between abdominal soft tissue motion in healthy volunteers and in cancer patients with the goal of developing a better way to manage and minimize the abdominal soft tissue motion. Accurate location of the tumor is very important in treatment delivery and reduction of toxicity.
