Abstract
Unique large-format publication from the field of gynecological ultrasonography. Ultrasound imaging, thanks to technical advances, reaches a "histological" level, which makes it possible to convincingly visualize the very early stages of fetal development.
For this type of view, the term sonoembryology was used. The most important prerequisite for the development of ultrasonography in the first trimester was the development of transvaginal ultrasonography using high frequency probes.
The key importance of these hi-tech imaging methods is, among other things, the mass extensions of in vitro fertilization methods and the increase in surgical procedures in the uterus, where there is a need to monitor the status and location of the developing embryo from the earliest stages.
