| OBJECTIVEThe previous researches indicated that the grey scale increased in tissues for HIFU (high intensity focused ultrasound) irradiation, the real monitoring HIFU can be performed by measuring the B-ultrasound grey scale. The objective of this study was to investigate the relationship between tissue coagulative necrosis in rabbit muscle and B-ultrasound grey scale during HIFU,and the conclusion was validated in goat muscle. MATERIAL AND METHODS1 Study of the rule between the value of B-ultrasound grey Scale and tissue coagulative necrosis after HIFU irradiation rabbit muscle.1.1 The Study on the correlation between the volume of tissue coagulative necrosis and the value of grey scale after HIFU irradiation.Sixty new Zealand white rabbits were randomly divided into 10 groups (0s, 18s, 30s, 40s, 50s, 60s, 70s, 80s, 90s, 100s) according to exposure duration. The treatmental parameters were with a Power of 140W,... |
