In typical practice today, clinicians in the fields of interventional radiology, radiation therapy, neurology, cardiology, and other spaces often utilize multiple techniques to prepare, image, and treat patients for complex, image-guided procedures. Such procedures may utilize one of x-ray imaging, computed tomography (CT), magnetic resonance imaging (MRI), fluoroscopy, angiography, among others, or combinations thereof to combine the strengths of each modality while minimizing undesirable tradeoffs. An objective problem exists of how to track the position and/or orientation of a patient transfer apparatus or support while it is in use on diagnostic and therapeutic modalities, independent of the inbuilt or external tracking measures of the modality, which is especially needed in light of today's modern multimodal diagnostic and treatment procedures. The present invention is directed to system and methods for tracking the coordinates of a patient transfer apparatus with selected sensors, transmitters, processors, and reference surfaces having tracking features capable of being detected by the sensors.
The present invention aims to provide a more efficient, customizable solution to achieve the desired level of immobilization. An inflatable cushion apparatus is designed to snugly position the patient within a head holder. The apparatus is provided with various features enabling customization of the immobilization, such as variable capability to restrict or enable inflation to selected portions of the apparatus. The apparatus is further provided with other features to accommodate a variety of clinical workflows, such as radiolucency, MR compatibility, means to maintain pressure within the apparatus, means to accommodate straps and accessories, and considerations for a sterile environment. The apparatus may further be used as part of a system for interventional radiology procedures also provided as another aspect of this invention. Finally, methods of use of the apparatus and the system are provided as yet more aspects of the present invention.
