    摘要: A method of phase imaging uses X-ray beams having edges overlapping with pixels. A phase image may be obtained from first and second images using one or more X-ray beam, the first image being measured with the first edge but not the second edge of each X-ray beam overlapping the corresponding pixel(s) and the second image being measured with the second edge but not the first edge overlapping the corresponding pixel(s). The gradient of the X-ray absorption function may be calculated and a proportional term included in the image processing to calculate a quantitative phase image.

    摘要: A method of aligning masks for phase imaging or phase contrast imaging in X-ray apparatus using a pixel-type X-ray detector makes use of non-idealities of all real detectors. A mask may be provided before the sample to generate beams, adjacent to the pixels of the detector or both. The method includes moving the mask into a plurality of translational position increments and identifying the increment for which the intensity has a maximum or minimum. The identified value of the increment may vary over the pixels of the detector. Alignment positions are selected in which steps in a plot of the increment over the area of the detector are minimized and/or aligned with the rows and columns of pixels.

    摘要: A method, system, and article of manufacture are described for interactive control of multiple images with a high dynamic range that are displayed simultaneously. A medical image control engine provides several synchronous functional capabilities, which comprises an input module, a blending factor synchronization module, a window/level synchronization module, a display module, and an image storage. For window/level adjustment of two images in blended views, the blending factor synchronization module is configured to automatically link the activation of a window/level control of one image with a transparency blending factor that affects both images. For synchronization of window/level adjustments of two or more images, a window/level synchronization module is configured to automatically change window/level parameters of all remaining images when the user makes an adjustment to a window/level control of one image such that all images with updated window/level parameters are displayed simultaneously.

    摘要: A system for dispensing a customised nutritional serving is made up of ingredients stored within a device incorporating the system. The device has a controller in whose memory is stored an inventory of the ingredients available in the device, their compositions and properties and customer profile data. The controller is programmed to formulate a serving which best matches the customised serving selected by the customer within constraints set by the programming taking into account the inventory of ingredients and the health profile of the customer. The customer is then presented with the selected serving and either accepts it or modifies it. The device is then programmed to prepare and dispense the final selection.

    摘要: An apparatus for modulating an intensity of a radiation beam includes a filter having a cross sectional shape such that a radiation beam filtered therethrough and passed through a patient will have an intensity that is substantially non-uniform. An apparatus for modulating an intensity of a radiation beam generated by a radiation source includes a filter, and a positioner secured to the filter, the positioner configured to move the filter relative to the radiation source.
