摘要： PROBLEM TO BE SOLVED: To provide an X-ray image processing method for detecting opacity by an X-ray image. SOLUTION: Algorithm for detecting the opacity according to those contrasts is proposed. In order to decide the contrasts which are not excessively presumed in each element, algorithm is proposed for computing background intensity by slide window filtering. This kind of slide window filtering computes the gathering of the average value of a gray level along the nearby circumstances of an element domain. The size of the element domain is dependent upon the size of the opacity to be detected. The algorithm regards as the background intensity of the element domain the average value of a minimum gray level among the gathering of the average value of the gray level.

摘要： PROBLEM TO BE SOLVED: To provide a method for acquiring tomosynthesis image with an enhanced optionality for detecting radiological indications.
SOLUTION: The present invention suggests a policy for radiation dose distribution regarding a method to acquire tomosynthesis image with an enhanced optionality for detecting radiological indications. This policy is defined as a function for substantially even depth of focus for different size and kind of radiological indications. This policy is combined with a digital filter processing for the purpose of ensuring an optimal transmission beyond the frequency spectrum of the signal versus noise ratio. The digital filter processing is performed by the adaptive filter of a class required when controlling the noise transmission which is being re-structured. The filter to be adapted to each projection of X-ray tube (4) depends on the dose distributed to the projection.

摘要： PROBLEM TO BE SOLVED: To minimize acquisition time, to obtain the complete modeling of an imaging object organ, and furthermore, to reduce noises of the image and the reconstructed volume in a contrast-enhanced digital breast tomosynthesis (CE-DBT).SOLUTION: An image is acquired according to various orientations of a radiation source. The acquisition corresponding to at least different first and second orientation mass of the emission radiation source is adapted. In the case of the orientations belonging to the first orientation mass but not to the second orientation mass, only one image each for the respective orientations is acquired, whereas in the case of orientations of the second orientation mass, at least two images each for the respective orientations are acquired for separate acquisition parameters.
