Abstract: Three dimensional X-ray imaging systems are described in this application. In particular, this application describes a 3D dental intra-oral imaging (3DIO) system and associated methods using a series of 2D image projections. The methods include making a 3D image of an object by providing an X-ray source on a first side of a object to be imaged, positioning a substantially stationary X-ray detector on an opposite side of the object from the X-ray source, moving the X-ray source in a circular motion to multiple positions on the first side of the object, collecting multiple two dimensional (2D) images of the object in less than about 10 seconds when the X-ray source is located in the multiple positions, and reconstructing a three-dimensional (3D) image using the multiple 2D images. In some methods, 15 to 100 2D images of the object can be collected by pulsing the X-ray source for about 5 ms to about 40 ms per image in each of the multiple positions.

Abstract: Sterile barriers or sterile drapes that can be used with medical devices, including hand-held or self-supported X-ray equipment, are described in this application. In particular, this application describes sterile drapes that can be used with a medical device, the drape comprising a closed end portion, a middle portion with a size sufficient to enclose a part of the medical device being used near a patient, and an open end portion, the end portion configured to be closed by a user once the middle portion encloses the part of the medical device being used near a patient, wherein the sterile drape creates a sterile barrier around substantially the entire medical device once the open end is closed. Using the sterile drape allows the medical device, such as a hand-held or self-supported X-ray device, to be used in a medical procedure that requires a sterile field near the patient without disrupting that sterile field. Other embodiments are described.

In particular, this application describes a 3D dental intra-oral imaging (3DIO) system that collects a series of 2D image projections. The 2D images are taken at different X-ray source positions located on a circle that defines the base of a regular geometric cone with the intraoral sensor located at the apex of that cone.

Abstract: A microwave applicator for insertion into living body tissue for use in microwave coagulation and ablation treatments includes a microwave transmission line extending between an attachment end of the applicator and an antenna toward an insertion end of the applicator with an outer conductive sleeve forming an enclosed cooling fluid space around the transmission line. Circulation of cooling fluid is guided in the cooling fluid space by a guide sleeve. A fluid circulation system provides a plurality of fluid supply connectors and fluid return connectors which can be connected and used with any number of applicators between one and the number of the fluid supply connectors provided by the system. A portion of the applicator inserted into the tissue can stick to the tissue to stabilize the applicator during treatment. A warning marking on the applicator can be used during track ablation to prevent ablation of the patient skin tissue.
