Title:
超音波波形断層撮影方法を用いた組織撮像および分析
Document Type and Number:
Japanese Patent JP7085470
Kind Code:
B2
Abstract:
This application presents a system and related methods that analyze a volume of tissue using ultrasound waveform tomography imaging. By using frequency-domain waveform tomography techniques and a gradient descent algorithm, the system can reconstruct the sound speed distributions of a volume of tissue, such as breast tissue, of varying densities with different types of lesions. By allowing sound speed to have an imaginary component that characterizes sound attenuation, the system can classify the different types of lesions with a fine granularity.
