A METHOD OF OBTAINING X-RAY IMAGES

WIPO Patent Application WO/2021/009476

A1

To obtain functional information (110) of a first object (20) obscured by a second object, with relatively low radiation dosage, a method is described of providing an x-ray imaging apparatus (10) comprising a panel (30) including an array of individually energisable x-ray emitters, a detector (40) and a processor (50), wherein the array and the detector remain stationary relative to one another and at least a portion of the second object; energising a first set of x-ray emitters of the panel over a first period of time and directing the x-rays at the first object; using the detector to detect the x-rays (35) after passing through the first object; processing the detected x-rays to create a first set of images to obtain tomosynthesis data (100) showing the structure of the first object; energising a second set of x-ray emitters of the panel over a second period of time and directing the x-rays at the first object; using the detector to detect the x-rays after passing through the first object; processing the detected x-rays to create a second set of images to obtain tomosynthesis data showing the structure of the first object, wherein the number of emitters used in the second period of time is less than the number of emitters used in the first period of time; and comparing at least some images from each set of images to provide functional information relating to the density of the first object.
