Primary Outcome Measures

Name	Time	Method
<p>To compare respiratory waveforms generated using the standard method with two<br /><br>new measurement systems. The generated waveforms will also be correlated with<br /><br>tumour position and movement. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>1. Determine if gating parameters derived from either magnetic or belt sensors<br /><br>can substitute for data from the presently used RPM system.<br /><br>2. Develop improved strategies for delivering respiration-gated radiotherapy<br /><br>(RGRT) using multiple respiratory signals </p><br>
