| 摘要 |
Ultrasound systems and methods for detecting features of biological tissue, including fracture detection in bone tumor detection are described. Systems and methods may employ low transient pulse technology. Methods employ detection and analysis of behavioral patterns of different signal parameters such as flight time, maximum amplitude, phase angle, and correlation as indicators of the depth of a fracture and may be used in quantitative ultrasound bone fracture detection. Flight time and frequency components may be employed in tumor detection methods.
