Abstract: A quality assurance phantom configured for connection to a x-ray device including a housing member having an opening configured to receive a digital sensor, a frame member disposed within the housing member, the frame member configured to receive a phantom device, the phantom device comprising, a contrast layer configured to assess a contrast resolution, wherein the contrast layer is configured to provide two or more different contrast levels, and a spatial resolution test layer, wherein the spatial resolution test layer includes at least one trace disposed on a first surface of a substrate, and an attachment member configured to detachably secure the housing member to the x-ray device.

Abstract: A radio-opaque plastic scintillator detector (PSD) for use in various medical applications and methods of making and using the PSD. The method requires coating a plastic scintillator fiber with a radio-opaque material; cutting the scintillator fiber; stripping the end of a plastic fiber optic fiber; cutting the naked end of a plastic fiber optic fiber; inserting a closely fitting guide tube over the naked end and inserting the cut scintillating fiber into the guide tube; coating the detector end of the cable with a light opaque polymer or jacket and adding a connector to the other end.

Abstract: A radio-opaque plastic scintillator detector (PSD) for use in various head and neck radiation applications is described. Bite plates, nose cones and ear cones are provided for use therewith, each having hollow tubes into which PSD cables can be inserted for real time measurement of radiation during treatment.

Abstract: A simple method of making robust radiation sensor cables using a special fiber cap that holds a scintillating fiber therein directly abutting an end of a fiber optic cable, thus providing a clean and protected connection therebetween.

Abstract: A prostate immobilizing balloon having a central seating area that on full inflation cups the prostate to hold it during treatment is combined with a gas lumen, a locking member and one or more fiducial markers. Methods of using same are also provided.

Abstract: A wearable dosimeter providing real-time radiation measurements based on sensitive, high gain scintillator crystals and a multipixel photon counter.

Abstract: A multilayer marine wrapping is proposed wherein each layer has a removal strip and the removal strips are staggered, such that a single layer can be removed at a time.

Abstract: A uni- or multi-channel cylinder brachytherapy applicator is combined with real-time radiation sensor cables, as well as methods of making and using same.

Abstract: A skin patch sensor having a groove therein to receive a sensor without leaving any air pockets is described. The skin patch sensor also has a water or tissue equivalent material and/or, in some embodiments, a moldable water equivalent material.

Abstract: A prostate immobilizing balloon that on full inflation cups the prostate to hold it during treatment is combined with a locking member so that the balloon does not shift during use. Methods of using same are also provided.

Abstract: A rectal balloon apparatus comprises a shaft having a fluid passageway extending therethrough. A rectal gas relieving lumen may be positioned with a central shaft for removal of rectal gas. The gas releasing lumen can also or in the alternative be provided along an outer surface of the balloon. A motion detecting sensor and a radiation detecting sensor may be positioned with the balloon, the shaft, and/or the rectal gas release lumen.

Abstract: A brachytherapy balloon system, including a brachytherapy applicator and a brachytherapy balloon, is described. The brachytherapy balloon is shaped and sized to fit a vagina, a rectum or an esophagus and is made of elastomeric polymer and has a cylindrical inner surface defining an interior hollow of diameter D with at least one open end into which a brachytherapy applicator of diameter x<D can fit, and an outer surface. The inner and outer surfaces of the brachytherapy balloon together define an inflatable elongated toroidal shape having a distal and a proximal end. The distal end has a diameter less than x, a valve for inflating the balloon, and a retention ring that prevents the brachytherapy applicator from protruding beyond the retention ring and reproducibly positioning the applicator on every use.
