Patent ID: 7672807

Claim:
An ultrasonic color imaging method to be applied with an ultrasound apparatus, comprising: a) accessing a trace of ultrasound signals provided directly or indirectly by said ultrasound apparatus, wherein said trace covers repeated trips of said ultrasound signals on a same main path within a target, and said repeated trips were forced by multiple reflections of exterior and interior interfaces of said target, wherein said ultrasound apparatus further performs the steps of: b) preparing an array of sequenced numerical data substantially rooted from said trace of ultrasound signals, c) selecting a plurality of data members from said array of sequenced numerical data such that selected data members were respectively and effectively influenced by same geometric position on said main path during different repeated trips of said ultrasound signals, and d) calculating a plurality of color parameters from said selected data members to express said geometric position on said main path into an image element of a color image, whereby the information arising from a plurality of said repeated sound trips is complementarily incorporated into the color image such that the color image is substantially more discriminative, descriptive, and position-sensitive to distributional acoustic characteristics of said target.
