Purpose To investigate the relationship between the TCD higher blood flow velocity and the pathology of internal cranial arteries,so as to improve the veracity of diagnosing cerebrovasculer diseases by TCD.

The blood flow parameter of central retinal artery,short posterior ciliary artery(PCAs) and ophthalmic artery were measured with color Doppler flow imaging(CDFI) in 60 eyes before and after acupuncture.

Objective: To study the effect of Xiaoyu Tablet (XYT) on blood flow parameters and morphology of carotid artery in atherosclerotic patients.

Objective To detect the changes of blood flow parameter on anterior ischemic optic neuropathy(AION)by color Doppler flow imaging(CDFI)before and after acupuncture,and to evaluate its clinical application value.

A newly module is developed to monitor cardiovascular hemodynamic parameters continuously and non-invasion by using blood volume pulse.

Color Doppler Ultrasonographic Analysis on Hemodynamics of Different Renal Artery Grades in Progressive Hepatic Cirrhosis;

It can not only detect and display pulse wave, but also compute Blood Flow Parameters litter more than teen and communicate with host computer.

Methods Blood flow parameters of middle cerebral artery and head circumference were assessed in 17 fetus with hyperdynamic circulation at 17 to 31 weeks gestation and 215 normal fetus at 16 to 31 weeks gestation by two dimension imaging, color Doppler power imaging and pulsed Doppler.

Methods Blood flow parameters of middle cerebral artery,head circumference and fetal weight were assessed in 215 normal fetus at 16 to 31 weeks gestation by two dimension imaging, color Doppler power imaging and pulsed Doppler.
