A multi-scale image processing algorithm for enhancing contrast in an electronic representation of an image represented by a) decomposing said digital image into a set of detail images at multiple resolution levels and a residual image at a resolution level lower than said multiple resolution levels, b) processing at least one pixel of said detail images, c) computing a processed image by applying a reconstruction algorithm to the residual image and the processed detail images, said reconstruction algorithm being such that if it were applied to the residual image and the detail images without processing, then said digital image or a close approximation thereof would be obtained. The processing comprises the steps of: d) calculating for said pixel, at least one statistical measure for two or more translation difference image pixel values within a neighbourhood of said pixel; and e) modifying the value of said pixel of said detail images as a function of said statistical measure and said value of said pixel of said detail images.

This invention is related to a multi-scale image processing algorithm for enhancing contrast to noise ratio in an electronic representation of an image represented by a) decomposing said digital image into a set of detail images at multiple resolution levels and a residual image at a resolution level lower than said multiple resolution levels, b) processing said detail images, c) computing a processed image by applying a reconstruction algorithm to the residual image and the processed detail images, said reconstruction algorithm being such that if it were applied to the residual image and the detail images without processing, then said digital image or a close approximation thereof would be obtained. The processing comprises the steps of: d) calculating a local variance value for at least one detail image pixel within a neighbourhood of said detail image pixel; e) enhancing or suppressing at least one detail image pixel as a function of said local variance value and said detail image pixel value.

The present invention relates to a method to improve a radiography workflow, wherein multiple images are ordered to be performed. The ordered images may be part of different series and are presented to an operator for execution by means of a displayed order list. The method intends to improve the radiography workflow by means of automatically determining which of the ordered images is to be executed by the technologist, immediately after the acquisition of any of said images is performed. A trained neural network detects which of the ordered images will be taken based on the analysis of a reference image that is acquired alongside the radiograph, and that is acquired from the same perspective as the X-ray beam itself.

This invention is related to a rolling element assembly that can be integrated into a telescopic arm segment assembly, comprising a pair of auto-adjusting rolling elements, that assume their optimal mounting position between two concentric telescopic arm segments, as they are spring-loaded by the presence of a connecting spring element. The final adjustment and fixation of the rolling elements (comprising each a pair of rollers) can then be subsequently be performed with high precision.
