| abstract |
The invention comprises a patient respiration monitoring and/or control method and apparatus used in conjunction with multi-axis charged particle or proton beam radiation therapy of cancerous tumors. The respiration monitoring system uses thermal and/or force sensors to determine where a patient is in a respiration cycle in combination with a feedback signal control delivered to the patient to inform the patient when breath control is required. The resulting breath control is timed with charged particle delivery to the tumor to enhance accuracy, precision, and/or efficiency of tumor treatment. |
