Modelling Internal Hepatic Movement With an External Abdominal Marker
Recruitment status was: Recruiting

|Study Design:||Time Perspective: Prospective|
|Official Title:||Modelling Internal Hepatic Movement With an External Abdominal Marker Block for Use With a Real Time Position Monitoring System for Respiratory Gating|
|Study Start Date:||June 2006|
The study will use a real time position management (RPM) system for respiratory gating. The RPM system senses the respiration motion of the patient by tracking a pair of reflective markers on a lightweight "marker block" constructed of a synthetic material. This block is placed on the patient's abdomen.
During Radiotherapy, the beam is only switched on at pre-determined phases of respiration. The appropriate phase of respiration is determined by the RPM system. This implies a reliable correlation of external block motion to internal hepatic movement. This correlation is not a simple one, and requires "modeling".
