Development of a prediction model for target positioning by using diaphragm waveforms extracted from CBCT projection images

PURPOSE: To develop a prediction model (PM) for target positioning using diaphragm waveforms extracted from CBCT projection images. METHODS: Nineteen patients with lung cancer underwent orthogonal rotational kV x‐ray imaging lasting 70 s. IR markers placed on their abdominal surfaces and an implante...
