Скачать или смотреть The 12 Weeks Scan: 3D and 4D Ultrasound

This video demonstrates application of 3D and 4D ultrasound for early pregnancy anomaly scan at 11-13 weeks' gestation.
The clip illustrates the use of different 3D/4D techniques for assessment of fetal anatomy in the first trimester of pregnancy.
Surface rendering mode is used for examination of the fetal body, face and extremities.
3D multiplanar reconstruction, tomographic ultrasound imaging (TUI), omniview and 3D inversion mode are utilized for first trimester transvaginal neurosonography and for storing and examination of the fetal volume data.
Spatio-temporal image correlation (STIC) is the cornerstone of the 4D fetal echocardiography. STIC volume data can be presented in rendering mode, multiplanar reconstruction or TUI. 4D fetal echocardiography can utilize grey scale, color Doppler, power Doppler, inversion mode and other different modalities.
STIC sonoandiography with color Doppler rendering and glass body technique is applied for examination of fetal vascular system.
Virtual organ computer-aided analysis (VOCAL) is used for calculation of the volumes of different fetal structures.
