Well, most of the time, pregnant women delivered positive reception about the ultrasounds. The main reason is that it reveals the health of the baby. So, pregnant women are always excited about their ultrasound scans.
In case, if the baby moves, the mothers become happy and excited. Also, witnessing the fetus also comes with a humanizing effect. It holds the moral significance for the women who were thinking of doing an abortion. Sometimes, it plays a significant role in decision making.
It helps a woman to understand whether she wants to keep the baby or not. A lot of people who are against the concept of abortion use the ultrasound imaging to show that the fetus is alive. Therefore, if you need to do an ultrasound, visit Morristown, New Jersey. There, you will find the Radiology center at Harding. They have some best tools in their collection. Radiology Center at Harding provides Top quality medical Imaging services to patients in Morris County and neighboring areas including.
Invention of ultrasound Well, in the year of , ultrasound was first used for medical purposes. What is the working principle of ultrasound? In , SY Sokolov , a Soviet physicist, first proposed the idea of ultrasound to find flaws deep in metal structures.
Indeed the successful use of ultrasound in industry predated its introduction into clinical medicine. These early sonographic methods in industrial manufacture used "through transmission". A receiver on the opposing side of the material to the ultrasound transmitter detected the sound waves as they passed through the material under testing, creating 'shadows' that could be interpreted.
During the s, efforts to use reflective techniques were made, which of course required that the receiver was on the same side of the material as the transmitter. Donald Sproule , a researcher working in England in created a system in which the receiver was a separate device collecting the waves that had bounced off the material.
In , Floyd Firestone , working in the US, received a patent for the Reflectoscope, the first system in which the same transducer both generated the ultrasound waves, and also detected the reflected waves, in the time between transmitted wave pulses. In , Karl Dussik , an Austrian physician, and his brother Friederick , a physicist, introduced hyperphonography, a technique which used ultrasound to visualize the cerebral ventricles.
Unfortunately, W Guttner, working in Germany showed that the apparent 'pictures' of ventricles were nothing of the kind, but instead represented densities of different parts of the overlying skull!
George Ludwig , working at the Naval Military Research Institute, in the United States, in , carried out research into gallstones embedded in soft tissues, using a through transmission technique. His pioneering investigations into the interactions between ultrasonic waves and animal tissues, helped lay the foundations for the later successful use of ultrasound in medical practice. Ian Donald introduced the ultrasound in diagnostic and medicine in , when he used the one-dimensional A-mode amplitude mode to measure the parietal diameter of the fetal head.
Two years later, Donald and Brown presented the ultrasound image of a female genital tumor. A decade later the Doppler effect served as the basis for the construction of the device that enabled the visualization of blood circulation, color flow Doppler ultrasound.

Log In. There is however a question: What is ultrasound? Well, we may define the ultrasounds as the sound waves with a very high frequency, above the audible frequency range and which cannot be perceived by the human ear.
In fact, these are the counterparts of UVs in the visual field. Therefore, the chances that the baby can perceive ultrasounds are almost nonexistent. Ultrasounds have been used in medicine since the s, initially for therapeutic purposes and later on for diagnostic purposes. In obstetrics, their use began to show effective results in the s. Professor Ian Donald, who led a well-known medical centre in Glasgow, pioneered the early developments in obstetric ultrasounds.
