Gena Corea, “The Mother Machine: Reproductive Technologies from Artificial Insemination to Artificial Wombs”, 1986 was the topic of an earlier blog post.
Amniocentesis is the withdrawal of amniotic fluid surrounding a baby in the womb. The methodology requires a needle insertion using ultrasound imaging to avoid touching the child with the needle (shown BELOW).

- SUMMARY
- In 1956, in Copenhagen DENMARK, Fritz Fuchs and Povi Riis using an “ultrasound transducer” (shown BELOW) saw displayed on CRT Screen sonogram imaging inside the womb.
Lithium Niobium Trioxide is a piezoelectric that is standard today for ultrasound transducers (shown ABOVE). The inverse of piezoelectricity is ultrasound generation.- Sonograms using ultrasound are harmless, safe method of imaging for amniocentesis of sex determination chromosomes. The needle held in one hand; and, the ultrasound transducer held in the other hand became a workable methodology.
