摘要： A desitometer gantry may translate in two directions for scanning and may swivel about a vertical axis to allow the radiation angle and the detector-to-patient distance to be altered during a scan so as to provide constant magnification of the image and to align the patient's spine with the radiation beam for more accurate edge measurements. A method of reducing the effects of osteophytes on density measurements applies an iterative threshold based on the density difference between hard and soft tissue.

摘要： A system and method is disclosed for utilizing image pixel value information generated by a digital radiographic system for quantifying the amount of calcium in a particular object of interest within a subject, wherein the subject also contains additional quantities of calcium located at positions such that the additional calcium interfers with the acquisition of data describing the object of interest. A cursor configured as a parallelogram is described and pixel values are summed along lines parallel to the sides of the parallelogram. A profile is generated from these summations. A portion of the profile corresponding to pixel lines not intersecting the object of interest is used to estimate the contribution of background and other calcium to the profile as a whole, and this estimated value is subtracted from the total profile. Integration of the remainder of the profile provides a scalar value corresponding to the amount of calcium in the object of interest.

摘要： A digital radiographic system and method is disclosed having improved detector resolution. The system includes an X-ray source and a spaced detector assembly having several staggered columns of uniform square detector elements. The detector elements are thus arranged in interspersed rows with the center-to-center spacing between successive members of each row being about twice the lateral dimension of each square element. In response to incident X-radiation, each detector element produces an electrical charge signal indicative of the radiation. Power means actuates the source to propagate X-ray energy in a beam along a path toward the detector assembly, in which path a subject may be interposed for examination. Mechanism is provided for scanning the detector assembly, synchronously and in alignment with the X-ray beam, relative to a subject. The relative scanning motion is perpendicular to the columns of detector elements. Time delay and integrate circuitry is provided, separate from but coupled to the detector elements. Detector element electrical signals are sampled at successive increments of scanning motion equal to half the width of a detector element. Respective delay circuitry built into the time delay and integrate circuitry delays element output signals differently as a function of detector element spacing and sampling frequency, in order to superimpose data for each respective image pixel and to present all signals relating to each respective pixel simultaneously to a summing output for imaging.

摘要： A medical diagnostic apparatus (A) generates medical diagnostic data which is reconstructed by an imager (B) into an electronic image representation. The electronic image representation includes an array of digital pixel values which represent a gray scale intensity of a man-readable image displayed on a video monitor (62). An image improving circuit (C) replaces each pixel value I(i,j) with an improved pixel value I'(i,j) defined as follows:I'(i,j)=G(i,j)[I(i,j)-I(i,j)]+I(i,j),where G(i,j) is a transfer function uniquely defined for each pixel and I is the mean of pixel values of neighboring pixels. The transfer function is based on a self-similarity value which is derived by comparing (i) a variation between the pixel value I(i,j) and pixel values in a first surrounding ring with (ii) a variation between the pixel value I(i,j) and pixel values in a second, larger surrounding ring. A zoom circuit (D) enlarges a selected portion of an improved image. Empty or unfilled pixel values I(inter) are interpolated from a combination of an average of neighboring pixel values I(avg) and a fractal value. The fractal value is a combination of a random number and a weighting factor R determined in accordance with the average self-similarity value of the neighboring filled pixels, i.e.:I(inter)=I(avg)+R.multidot.(random#).
