Abstract
Conventional ultrasound imaging presents the amplitude of scattering and reflecting signals by brightness whereas neglecting the spectral information. However, ultrasonic harmonic imaging demonstrated that ultrasonic signals carry abundant and various spectral information. In this research, we propose a spectrum enhanced colour ultrasound imaging method that elucidates ultrasonic spectral patterns in ultrasound images. First, continuous wavelet transform upon the ultrasound signals exhibited the spectra at various positions. Second, principal component analysis concentrated major information within the first dimensions. Third, the dataset was projected into the eigenspace, and the coordinates were colour-coded to make colour ultrasound images. The technique differentiated tissues based on their spectral patterns, which may lead to easy interpretation of ultrasound images, pioneering an advanced approach in the future.
