With shorter wavelengths than microwaves and greater penetration depth infrared light, waves in the terahertz spectrum offer unique material testing opportunities. Terahertz technology offers non-invasive non-destructive form of spectroscopy imaging. The most used systems for imaging are time-domain systems. However, frequency domain could excellent resolution be more suitable biomedical applic...

To assess the usefulness of continuous wave Doppler echocardiography in the evaluation of aortic insufficiency, the aortic regurgitant flow velocity pattern obtained with continuous wave Doppler examination was compared with the results of aortography and conventional pulsed Doppler techniques in 25 individuals with aortic insufficiency. The diastolic deceleration slope as measured from the con...
