Brief Summary
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.

Outcome Measures
Primary Outcomes (3)
Abdominal Soft-tissue Movement
Measuring changes in abdominal soft-tissue movement through 4D ultrasound system
change in abdominal soft-tissue movement from baseline to 3 weeks
Tissue Change During Radiation Treatment
monitoring of tumor and surrounding organ/tissue during pancreas and liver SBRT treatments using 4D ultrasound system
change in tumor tissue from baseline to 3 weeks
Change 4D Ultrasound to Traditional Cone-beam Computed Tomography (CBCT) Monitoring
Evaluate accuracy of the 4D ultrasound motion monitoring system compare to CBCT based intra-fraction motion monitoring during pancreas and liver SBRT treatments
change in imaging studies of 4D ultrasound from baseline to 3 weeks
Secondary Outcomes (1)
Change in Dosimetry Measurements
dosimetric changes in abdominal soft-tissue movement from baseline to the end of radiation treatment at 3 weeks
Study Arms (3)
Pancreatic Cancer
ACTIVE COMPARATORA 4D ultrasound scan of the pancreas will be acquired at the time at simulation and used as a reference ultrasound image for localizing tracking target. The ultrasound probe will be placed at the abdominal area to monitor the pancreas motion. The probe will remain in place during the CT scan. Patient setup and the ultrasound probe location will be recorded so that the same setup can be reproduced during treatment delivery. The ultrasound probe in the CT image will be contoured and radiation beams that directly pass through the ultrasound probe will be avoided. On each treatment day, 4D ultrasound images will be acquired continuously during beam on time to monitor pancreas motion. Intra-fraction CBCT images acquired during treatment will be registered with reference CT images. Organ motion registered by ultrasound will be compared to motion recorded by CBCT and the accuracy of the ultrasound system will be evaluated.
Liver Cancer
ACTIVE COMPARATORA 4D ultrasound scan of the liver will be acquired at the time at simulation and used as a reference ultrasound image for localizing tracking target. The ultrasound probe will be placed at the abdominal area to monitor the liver motion. The probe will remain in place during the CT scan. Patient setup and the ultrasound probe location will be recorded so that the same setup could be reproduced during treatment delivery. On each treatment day, 4D ultrasound images will be acquired continuously during beam on time to monitor liver motion. The system will record all relevant images, but will not be used in clinical decision making. Intra-fraction CBCT images acquired during treatment will be registered with reference CT images. Organ motion registered by ultrasound will be compared to motion recorded by CBCT and the accuracy of the ultrasound system will be evaluated.
Healthy Volunteer
OTHERA reference ultrasound scan will be conducted on each subject during breath-hold. Subjects will be required to lie in supine position and engaged with ABC; an ultrasound probe will be placed at the abdomen area with minimal pressure applied. Continuous motion monitoring is achieved by acquiring 4D ultrasound images using a motorized 3D ultrasound probe to image the pancreas, liver and other intra-abdominal organs continuously. Several 4D ultrasound scans will be collected during subsequent breath-holds that serve as secondary images. Additional registration of ultrasound images will be performed with Velocity software to evaluate accuracy of automated registration software in the ultrasound system.
Interventions
A 4D ultrasound scan will be acquired at the time at simulation and used as a reference ultrasound image for localizing tracking target. The ultrasound probe will be placed at the abdominal area to monitor the pancreas motion. The probe will remain in place during the CT scan. Patient setup and the ultrasound probe location will be recorded so that the same setup can be reproduced during treatment delivery.
