摘要： The noise is eliminated from the images by carrying out a first Fourier transform of the images of an original batch of images. Each of these transformed images is then broken down into Fourier series to reveal the main harmonics of a periodic evolution of the original images and of the transformed images. This harmonic breakdown is used to recompose transformed images that are thus filtered by the abandoning of the non-useful harmonics. The filtered transformed images are used to carry out a reverse Fourier transform to obtain, ultimately, filtered original images. It is shown that the filtering in this case removes the noise without lowering the quality of the structures of the image, without distributing the noise among all these structures.

摘要： An x-ray imaging apparatus includes a holdable housing; an x-ray source mounted within the housing and configured to output a fan beam of x-rays; and a hoop chopper wheel rotatably mounted within the housing and comprising an x-ray attenuating material configured to block x-rays of the fan beam. The hoop chopper wheel defines a set of beam apertures of which each aperture is configured to pass therethrough a corresponding angular portion of x-rays from the fan beam, so that rotation of the hoop chopper wheel causes scanning of the corresponding angular portion of x-rays. The x-ray source may be a transmission-type x-ray tube configured to output the fan beam centered in an x-ray extraction direction forming an angle greater than 0 degrees with respect to a longitudinal axis of the x-ray tube.

摘要： A radiographing control apparatus emits radiation to an object and obtains a plurality of frame images to control dynamic radiographing that radiographs dynamics of the object. The radiographing control apparatus includes a hardware processor. The hardware processor obtains first order information that includes at least one of information on presence or absence of dynamic analysis executed for a dynamic image obtained by the dynamic radiographing, and information on a dynamic analysis item, determines a first radiographing condition and a target image quality, based on the obtained first order information, and determines a second radiographing condition for achieving the determined target image quality.

摘要： The present invention relates to a method for determining the distribution of an imaging agent in a volume. The method comprises the acquisition of at least one three-dimensional functional image of the volume; the segmentation of the volume into one or more compartments; the representation of the three-dimensional imaging agent activity from the functional image by the product of a scaling factor and a non-affine transformation of a template imaging agent activity; the calculation of a projected imaging agent activity from the thus represented imaging agent activity on a planar surface; the acquisition of a planar image of the imaging agent activity in the volume; the registration of the projected imaging agent activity with the planar image; the comparison of the acquired planar image with the calculated projected imaging agent activity; and the modification of the representation of the three-dimensional imaging agent activity.

摘要： According to a first aspect of the invention there is provided a system of and method for processing a digitized image derived from detector instrumentation (11) to form a reconstructed image. In a typical image processing system (9), γ-rays (10) impinge upon a gamma camera unit (11), defining detector instrumentation, and then pass through a lead collimator (12) to cause a scintillator (14) to emit light in the visible electromagnetic spectrum at given locations above an array of analogue photomultiplier tubes (16). With appropriate circuitry (18) these analogue signals may then be digitized, by means of processor (20), and then stored in memory (22). The present invention aims to more accurately reconstruct these digital images, with, in broad terms, the raw data stored in memory (22) being sent to a processor (24), which processes the data in terms of algorithms that form part of the invention. According to a further aspect of the invention there is provided a method of processing a digitized phantom image derived from detector instrumentation to form a reconstructed point spread function image.
