Abstract: In a X-ray imaging apparatus an estimation unit estimates a cumulative exposure dose of X-rays irradiated onto an object, and a remaining exposure tolerance dose calculation unit calculates a remaining exposure tolerance dose using a difference between a tolerated maximum exposure dose and the cumulative exposure dose. A X-ray irradiation tolerance period calculation unit calculates an X-ray irradiation tolerance period using a difference between a predetermined scheduled X-ray irradiation period and an actual irradiation period of X-rays irradiated onto the object, an X-ray irradiation reference dose calculation unit calculates reference dose per unit time that will form a basis for irradiation based on the remaining exposure tolerance dose and the X-ray irradiation tolerance period, and a control unit that controls X-ray irradiation of the object by setting dose per unit time within the X-ray irradiation tolerance period based on the reference dose.

Abstract: A memory stores first image data for offset correction generated by performing an interlace scanning of the driving lines of odd rows only in a driving circuit unit. A memory stores second image data for offset correction generated by performing the interlace scanning of the driving lines of even rows only in the driving circuit unit. A processing unit synthesizes the first image data for offset correction and the second image data for offset correction, thereby to generate image data for offset correction of one frame portion, and an arithmetic operation unit performs an arithmetic operation processing on the radiation image data by using the image data for offset correction of one frame portion synthesized and generated, thereby to perform the offset correction of the radiation image data.

Abstract: A method and apparatus for tracking a pathological anatomy within a patient's body is described. A data model of a skin surface of the patient's body may be acquired using light reflected from the skin surface. The data model can be matched with skin surfaces reconstructed and/or interpolated from four-dimensional (4D) diagnostic imaging data, such as 4D CT data, to determine a temporal phase of the patient's respiratory motion. The identified temporal phase may then be used in conjunction with the diagnostic imaging data to identify a location of the pathological anatomy within the patient's body.

Abstract: A stereotactic breast biopsy apparatus and system that may comprise an x-ray source, a digital imaging receptor, and a biopsy specimen cassette, wherein the x-ray source is provided with a means for displacing the beam axis of the x-ray source from a working biopsy corridor beam axis to permit an unobstructed illumination of the biopsy specimen and thereby produce biopsy x-ray images directly in the procedure room for immediate analysis. Some examples of the benefits may be, but are not limited to, a more rapid analysis of biopsy specimen digital images, post-processing image capability, and decreased procedure time and diminution of patient bleeding complications and needle discomfort.

Abstract: A CT scanner pre-scans a patient by radiating rays of a lower amount from one direction to obtain a perspective prescanning image. An operator defines a main scanning area, in which images for medical application are to be captured, with reference to the prescanning image displayed on a monitor screen. A site recognizer analyzes data of the prescanning image to recognize anatomical structures located in the defined main scanning area. Based on the recognized anatomical structures and order data designating a site of inspection, it is judged whether the main scanning area corresponds to the site of inspection designated by the order data. If not, a warning is displayed on the monitor screen. The site recognizer may recognize all anatomical structures contained in the prescanning image, so that a default main scanning area may be defined on the basis of the recognition results and the order data.

Abstract: A method is disclosed for compiling computer tomographic representations using a CT system with at least two angularly offset ray sources. A first ray cone with a relatively larger fan angle and a second ray cone with a relatively smaller fan angle scan an object circularly or spirally. The first ray cone generates a first dataset A and the second ray cone generates a dataset B. The dataset B of the smaller ray cone is supplemented with other data at the edge to give an expanded dataset B+ for reconstruction of the CT representation. The expanded dataset B+ of the second, smaller ray cone and the dataset A of the first, larger ray cone is subjected to a convolution operation to give datasets B+? and A?. Finally, a back projection to reconstruct sectional images or volume data is respectively carried out from the convoluted datasets B+? and A?. The dataset B is supplemented with data of the dataset A and supplementary data are removed from the dataset B+? after the convolution but before the back projection.

Abstract: In a method for the obtaining a tomosynthesis image for a more selective detection of radiology signs, a dose distribution strategy is proposed. The strategy is defined as a function of a substantially uniform depth-of-focus for a variety of sizes and classes of radiology signs. This strategy is coupled with a digital filtering aimed at ensuring optimum propagation of the signal-to-noise ratio beyond the frequency spectrum. This digital filtering is done by means of a class of adaptive filters required to control the propagation of the noise during the reconstruction. The filter to be applied to each projection of the X-ray tube (4) depends on the dose assigned to this projection.
