Relocatable stereotactic immobilization apparatus

摘要

A patient immobilization frame is provided that can be secured to a patient table in a radiation therapy facility. The frame includes fiducials integrated into the bottom panel of the frame. The frame is provided with a removable locking mechanism for locking the frame to the patient table. Each side walls of the frame defines a forward cut-out and a mid-side cut-out to accommodate larger girth patients. A panel insert is provided to close the mid-side cut-outs when the additional space is not required for the patient. The frame further includes an abdomen compression device supported by a cross bar that is movably mountable to the frame. The device includes a compression plate configured to contact the patient and a compression mechanism between the cross bar and the compression plate. A pressure transducer may be incorporated between the compression plate and the cross bar.
