Abstract: An X-ray imaging method includes in a digital X-ray detector including an array of discrete picture elements each including a photodiode and a transistor, applying a first voltage to the transistors of the discrete picture elements. The method also includes preparing for acquisition of X-ray image data by sampling data from the discrete picture elements while applying a second voltage to the transistors of the discrete picture elements not then being sampled, the second voltage being more negative than the first voltage. The method further includes receiving X-ray radiation on the detector from a source. The method yet further includes sampling X-ray image data from the discrete picture elements while applying the second voltage to the transistors of the discrete picture elements not then being sampled.

Abstract: PROBLEM TO BE SOLVED: To shorten a signal conversion time and to improve an X-ray image by executing the adjustment/correction of an offset signal. SOLUTION: A system and a method are for the offset correction of the image from a flat panel detector (112). In one example, one or two or more offset maps which are acquired for an imaging system (100) during the system idling are developed in two or more irradiation windows. Also, the offset map to be subtracted from a following X-ray image is selected using an irradiation parameter acquired for the imaging system before the image acquisition. In other example, one or two or more offset maps and the irradiation parameter are accumulated, and an executable command to direct processors (128 and 130) to subtract a noise element from the X-ray image on the basis of the selected offset map is disclosed so that the time between the image acquisition and the display of the processed image is made to be the shortest.

Abstract: PROBLEM TO BE SOLVED: To provide a novel method and system for correcting an application image so as to reduce the number of correction maps requiring maintenance. SOLUTION: Grid dedicated correction maps 151-153 and non-grid correction maps 154-156 are determined and the application image is corrected on the basis of the combination of these correction maps. In the other style, this device is provided with a computer readable medium storing software for automatically detecting/correcting a grid image inside the application image and calculating/ applying the grid dedicated and non-grid correction maps.

Abstract: PROBLEM TO BE SOLVED: To detect and control an improved dynamic range by generating a display map defining the relation between the dynamic range of an original medical image representing a patient and a target dynamic range and preparing an image having the target dynamic range based on the display map and the original medical image. SOLUTION: An image acquisition workstation 10 further includes display unit 28 and a user interface 30 and respectively acquires information from an operator. The workstation 10 includes at least one CPU 32 executing a processing system and a memory 34 to control the dynamic range of an acquired medical image. The workstation 10 generates a gray level-optical density model 42. The model 42 defines the concrete relation between the gray level of a digital detector 22 and desired optical density that is defined preliminarily or by an operator.

Abstract: PROBLEM TO BE SOLVED: To reduce an artifact mixed by a transition from a high radiation to a fluoroscopic-mode utilizing a low irradiation. SOLUTION: A method for processing a fluoroscopic image contains a method (30) for processing the fluoroscopic image provided in one example, a process (32) in which an object (12) is scanned by one or more of radiation sources (14), a process (34) in which a plurality of dark images are gained for forming a baseline image, a process (36) in which a plurality of delay images are gained in succession to the baseline image, a process (38) in which a plurality of parameters by an exponentiation rule are decided by using one or more of the delay images and one or more of the baseline images, and a process (40) in which a logarithm-to-logarithm extrapolation by the exponentiation rule containing the decided parameters is executed.

Abstract: Systems and methods are provided for managing power consumption of a medical imaging detector by the use of triggering signals, environmental condition data, and/or determination of a variable time interval triggering event that is unique for each power consumption state. Systems and methods are provided for managing power and temperature of a device, after receiving a request for a function to be performed by the device determining an "on" trigger component, an "off" trigger component, associated circuits for performing the received function, providing power to the associated circuits upon the occurrence of the "on" trigger component, and removing power to the associated circuits upon the occurrence of the "off" trigger component. Further, an instruction is described for determining and displaying a variable time interval that is indicative of a time to change from one state to a desired state.

Abstract: Il est proposé une technique de correction et d'étalonnage de gain pour systèmes d'imagerie numérique. Dans une forme de réalisation, un procédé peut comprendre l'acquisition (180, 184) d'une pluralité d'images sombres à l'aide d'un détecteur numérique d'un système de radiographie. L'acquisition de la pluralité d'images sombres peut comprendre l'acquisition de données à partir d'une pluralité de canaux de données du détecteur numérique pendant un mode d'essai analogique du détecteur numérique dans lequel des tensions d'étalonnage sont appliquées (178, 182) aux canaux de données. Le procédé peut aussi comprendre l'étalonnage (186) d'une mappe de gains de données du détecteur d'après la pluralité d'images sombres.
