20120219108 | APPARATUS FOR TOMOSYNTHESIS AND MAMMOGRAPHY - An apparatus for performing tomosynthesis and mammography of a breast of a patient, comprises: an X-ray detector device, designed to receive and detect X-rays in a first, detection plane; a plurality of X-ray sources, stably positioned in a second plane which is substantially at a right angle to the first, detection plane in a plurality of predetermined positions relative to the detector device, each of the sources being individually activatable for emitting a corresponding X-ray beam towards the first, detection plane; a region for positioning the breast; a processing and control unit, connected to the X-ray sources for activating them individually and connected to the detector device for receiving a signal relating to the X-rays which passed through the breast and were detected by the detector device, the unit being designed to derive from the signal at least one radiographic image representative of the internal structure of the patient's breast. | 08-30-2012 |
20120219109 | APPARATUS FOR TOMOSYNTHESIS AND MAMMOGRAPHY - An apparatus for performing-tomosynthesis and mammography includes an X-ray detector for receiving and detecting X-rays in a first, detection plane; a plurality of X-ray sources are positioned in a second plane substantially at a right angle to the first plane and which can be individually activated for emitting a corresponding X-ray beam towards the first, detection plane, at least a first part of the sources movable relative to the detector and including a first source mobile in a first direction of movement parallel with the first, detection plane for emitting X-rays from a plurality of operating positions along said first direction of movement; a region for positioning the breast; a processing and control unit, for controlling the X-ray sources and receiving a signal relating to the detected X-rays passed through the breast to derive radiographic image representative of the internal structure of the breast. | 08-30-2012 |
20120219110 | APPARATUS FOR MAMMOGRAPHY AND/OR TOMOSYNTHESIS WITH DEVICE FOR REMOVING DIFFUSE RADIATION - An apparatus for tomosynthesis and/or mammography includes: an X-ray detector, for receiving and detecting X-rays in a first, detection plane; an X-ray source, which can be activated individually and is positioned to emit a corresponding X-ray beam towards the first, detection plane; a processing and control unit, for activating the X-ray source and receiving a signal relating to X rays which passed through the breast and were detected by the detector to derive a radiographic image representative of the internal structure of the breast; a grille for removing diffuse radiation, interposed between the source and the detector to receive X-rays which passed through the breast. The grille including plates positioned opposite the chest of the patient when the breast is positioned in a positioning region, and which are angled to converge towards the same region proximal to the X-ray source. | 08-30-2012 |
20130281843 | APPARATUS FOR CARRYING OUT AN EXAMINATION ON THE BREAST OF A PATIENT - An apparatus for carrying out an examination on the breast of a patient, comprising an analysis head provided with at least one radiation detection device, configured to receive and detect radiation on a detection plane and at least one X-ray source to emit a corresponding beam of X-rays towards said detection plane, said machine comprising: a first frame provided with floor support means; a second frame supporting the analysis head; a third frame connected to the first frame so that it can be moved from a horizontal position to a vertical position, and which supports the second frame; means for movement of the third frame from said horizontal position to said vertical position. | 10-24-2013 |
