Title:
超音波カラードップライメージングの後処理のためのシステム及び方法
Document Type and Number:
Japanese Patent JP5068416
Kind Code:
B2
Abstract:
A system for ultrasonic imaging that includes a comparator for comparing at least one Doppler parameter input to a threshold value and generating a first mask. The comparator has a threshold value associated with each Doppler parameter input. A spatial filter is coupled to the comparator and produces a second mask, and a classification operator is coupled to the spatial filter and generates a third mask. The classification operator can effectively compare a value of a given pixel to the value of any nearby neighboring pixels and reclassify any given non-majority pixel to a majority value of the nearby neighboring pixels. An embodiment of the invention further includes a multi-parameter generator that outputs at least one Doppler parameter. The multi-parameter generator has a functional relationship based on at least one Doppler parameter input and at least one of any of the masks. A second spatial filter is coupled to receive the Doppler parameter input.
