For create Images at M – mode ultrasound before is and is accepted only by one the lines scan . This line choose with using cursor by two-dimensional image so that she is wasperpendicular is
followable structure . Sensor reject so way to cursor was strictly perpendicular image . Insofar as at M – mode spend scanning along
one line, it provides much more high forge temporary permitting ability at comparing with two-dimensional Echocardiography . it special important at research nii movable structures.
M – mode presents by myself graphic image niya strength and depths reflected signal at dependencies from of time . Visualized motion and thickness walls ventricles change sizescameras hearts as well also opening and closing valves .
Synchronous a record ECG allows exactly define temporary specifications different of events relationship respectfully cordial cycle . Similarly define temporary specifications blood flow at colored mapping .
CONSTANT WAVE DOPPLER RESEARCH
AT mode constantly – wave doppler research knowledge happens constant broadcast and reception ultra sound signal . Behind score of this is possible check in high speedswithout restrictions at the form effect distortions spectrum .
Technique constantly – wave doppler is following not allows exactly define a source reflected signal at the limits lengths or widths ultrasound ray .
The mode doppler research used are calling for fast search high speed streams at heart. Insofar as Doppler shift frequencies locat ditsya at heard range, for deductions the bestspectrum at deviation and rotation sensor use , in Tom among other things, audio. By the results constantly wave doppler research define optimal a place for installations controlvolume at pulsed research . Constantly – wave Doppler study use for ratings manifestations stenosis and definitions degrees untill fatigue . Also is possible quantitative assessmentintracardiac reset left to the right . By trance tricuspid constantly – wave spectrum can calculate pressure at pulmonary arteries .
