Abstract: A system and method of locally displaying multiple items of medical information from at least one remote medical system having an output display. The method includes assembling the multiple items of medical information from the output display of at least one remote medical systems into a composite display having regions corresponding to the multiple items of medical information. Video data for the composite display is communicated over a network to a local display. Video data corresponding to the regions of the display are treated differently to provide a composite display with regions of different image quality.

Abstract: A method and system for performing fluoroscopic imaging of a subject has high temporal and spatial resolution in a center portion of the captured dynamic images. The system provides for reduced X-ray dose to the patient associated with that part of the X-ray beam associated with a peripheral portion of the captured images although temporal, and in some embodiments spatial, resolution is reduced in the peripheral portion of the image. The system uses a rotating collimator to produce an X-ray beam having narrow wing portions associated with the peripheral portions of the image, and a broader central region associated with the high resolution center portion of the images.

Abstract: An integrated x-ray and ultrasound medical imaging system is provided, wherein a radiation detection means and ultrasound transducer may be disposed for scanning movement for image acquisition along either the same or substantially coincidental paths. The radiation detection means and ultrasound transducer may be advantageously located on the same side of the imaged body portion: The x-ray and ultrasound imaging operations may be sequential, partially overlapping, or synchronous. By virtue of the noted arrangement, increased accuracy and medical efficiencies can be realized.

Abstract: This invention describes methods for the design of checkerboards comprising two or more square patterns, one pattern being characterized by the predominant use of illustration, the second pattern being characterized by the predominant use of text. The invention also describes a method to generate a physical embodiment of the checkerboards from a printout image, and a method to add a sense of depth to the checkerboard squares by the use of holograms.

Abstract: Scatter effects are reduced in a radiographic imaging device, such as a digital slot scan mammographic imaging device, by reducing detected scatter and processing detector information to compensate for scatter effects. In one embodiment, a digital mammographic imaging system (10) includes a source (24) for transmitting a narrow beam (28) and a detector assembly (32) for detecting the beam (28). The beam (28) and the detector assembly (32) are synchronously scanned across the patient's breast (48) to obtain an image. Collimator slats (74) are provided at the leading and trailing edges of the detector to reduce detected scatter. Additionally, attenuators (76 and 92) are provided at the ends of the scanned motion and at the anterior edge of the detector array to assist in determining a spatial intensity profile.

Abstract: A system for low dose x-ray imaging provides for dynamic generation of an x-ray beam with specific shape, and dynamic tracking of a detector with said beam. The detector is rotatable, and translatable along two orthogonal axes, and may mount with a circular detector tray, the tray rotating around a rotation axis. Specific detector shapes include an elongated rectangular matrix, for example with additional detector cells near the rotation center to provide an increased area of continuous detection. Dynamic low-dose x-ray tomosynthesis or limited-angle tomographic imaging is enabled via simultaneous x-ray tube and detector motions during examination, such as fluoroscopic examination of a human body. Data acquired at multiple projection angles is input to a 3D image reconstruction algorithm that provides a refreshed 3D data set during continuing examination. The system may thus also automatically track a point in three-dimensional space, for example continuously locating the tip of a catheter.

Abstract: A multispectral X-ray imaging system uses a wideband source and filtration assembly to select for M sets of spectral data. Spectral characteristics may be dynamically adjusted in synchrony with scan excursions where an X-ray source, detector array, or body may be moved relative to one another in acquiring T sets of measurement data. The system may be used in projection imaging and/or CT imaging. Processed image data, such as a CT reconstructed image, may be decomposed onto basis functions for analytical processing of multispectral image data to facilitate computer assisted diagnostics. The system may perform this diagnostic function in medical applications and/or security applications.
