Description
This pilot study is focused on recognition and digital analysis
of atherosclerotic plaques in ultrasound B-images. The plaques are dis-
played as dierently echogenic regions depending on plaque composition.
The rst goal is to nd signicant features, e.g. homogenicity, shape and
size to plaque analysis from digitized ultrasound images. We developed
software to nding hyperechogenicity of substantia nigra to Parkinson's
Disease evaluation in B-images. Currently we try to discover how to use
this software also for atherosclerotic plaques analysis to estimation risk
level of ischemic stroke. The software has a built-up function of intelli-
gent brightness detection. We use a set of 23 images, each of them was
analyzed ve times. The primary goal is to verify the reproducibility of
this software to atherosclerotic plaques analysis in medical practice with
evaluation by an experienced sonographer. All used images in this study
have the same initial settings of gamma, contrast and brightness.
