Publication number: 20160213337Abstract: A heat formable patient positioning cushion is provided including an impermeable or permeable outer shell; a filler material contained within an interior region defined by the outer shell; and a thermoplastic material applied to the outer shell, to the filler material, or to the outer shell and the filler material. The cushion has a first condition configured to be conformed to the anatomy of a patient in which the filler material moves relatively freely within the interior region defined by the outer shell, and a second condition conformed to the anatomy of the patient in which the filler material is relatively fixed against movement within the interior region defined by the outer shell. Heating and cooling changes the cushion from the first condition to the second condition and reheating permits increased movement of the filler material as compared to the second condition to further conform the cushion to the anatomy of the patient.Type: ApplicationFiled: August 8, 2014Publication date: July 28, 2016Applicant: Qfix Systems, LLCInventors: Daniel D.

Patent number: 9179880Abstract: A radiation therapy patient couch top which provides optimal fields of treatment in a high-energy radiation therapy environment. In addition, the patient couch top provides superior imaging qualities when used in a diagnostic imaging x-ray environment. All metal is eliminated from the treatment/imaging area. This ensures that no metal will be in the way of the radiation treatment beam and that no artifacting will occur when used with diagnostic imaging techniques such as Computed Tomography. By employing moveable fiber reinforced support beams, the main patient support structure can be positioned so that a minimum of electron generation will occur through Compton scattering. By allowing for a removable insert, the top patient surface can be optimized for treatment, diagnostic imaging or the addition of other useful features.Type: GrantFiled: September 25, 2006Date of Patent: November 10, 2015Assignee: QFIX SYSTEMS, LLCInventors: Daniel D.

Publication number: 20080066231Abstract: A patient support device for accurately and repeatably positioning a patient for treatment. The device comprises a top surface, a bottom surface, two sides and at least two sidewalls. The device can include an integral indexing means and an accessory device adaptor for receiving various accessories. The device can incorporate chamfered edge technology and can include indexing grooves on at least one surface of the device.
