Title:
A METHOD OF OBTAINING X-RAY IMAGES
Document Type and Number:
WIPO Patent Application WO/2021/094758
Kind Code:
A1
Abstract:
To reduce dose without a reduction of the quality of x-ray images a method of obtaining x-ray images of a first object obscured by a second object is described; the method comprising the steps 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 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 and surrounding area; using the detector to detect the x-rays after passing through the first object and surrounding area; processing the detected x-rays to create a first x-ray image of the first object and surrounding area; selecting a region of interest (74) from the first x-ray image which is smaller than the image of the first object and surrounding area; energising a second set of x-ray emitters of the panel over a second period of time and directing the x-rays at the region of interest; using the detector to detect the x-rays after passing through the region of interest (74); and processing the detected x-rays to create a set of images (100) of the region of interest to obtain tomosynthesis data showing the structure of the region of interest.
