摘要:
Disclosed is a miniaturized phantom that can be placed against breast tissue during mammography. The phantom is provided with various radiological features that can be compared to the image of the breast tissue. The phantom is situated to be included in one or more mammography images. The phantom is at least partially opaque to the radiation of the image and contains features such as step wedges of different density, pillars that show radiation incidence, sweep gratings that show variations of radiation amplitude and a unique bar code to identify patients. The phantoms can be used in images containing them to assess various radiological features in a quantitative way.
