X-RAY IMAGING SYSTEM WITH DETECTOR HAVING PIXELS |
摘要 |
The invention relates to a method and an imaging system (100) for generating X-ray 101a 101b 101c 101d images. The system (100) comprises at least one X-ray source, preferably an array of X-ray sources (101a-101d), and an X-ray detector (103) with an array of sensitive pixels (103a-103e). A collimator (102) is arranged between the X-ray source and the detector such that two openings (P) of the collimator (102) allow the passage of X-rays towards two neighboring pixels (103a-103e) while the region between said pixels is substantially shielded. This shielding of the usually insensitive regions between pixels reduces unnecessary X-ray exposure. A sufficiently large X-ray intensity can be achieved by using a plurality of small X-ray sources (101a-101d). |
