Ultrasound is reflected from boundaries tissue deforms piezoelectric crystal and generates electric sky pulse which transformed at the point on the screen .
Brightness and position points depends on from of character and depths investigated structures .
For create two-dimensional Images ultrasonic Ray skipped through region interest . Ultrasound is transmitted along several (90-120) lines scanner of by wide ( about 90 ° ) arc up to20-30 times at second.
Summation reflected ultrasound waves form beats picture on the screen . Fast generation after respectable of images creates ” Living “ picture movable structures . Any frameliving Images can be “Frozen”, analyzed on the screen or printed out on thermal paper .
Two-dimensional Echocardiography allows to study anatomy hearts and relationship different structures .
With two-dimensional cardiography possibly revealing intracardiac formations and pathologies pericardium , visualized motion walls ventricles and leaflets valves .
Also spend measurement thickness walls wish daughters and sizes cameras, computed shock volume fraction emission and cordial overshoot .
Two-dimensional picture use at quality orientation shooting gallery at research at M – mode , and also at doppler – echocardiography for installations control volume .
