ultrasound
Some pathology will affect the image on medical ultrasound because it will reflect or absorb sound waves differently from the surrounding tissue, making a light or dark image on the screen that makes the pathology visible.
Commercially sold television receivers have always included a circuit for sound. Historically, the first successful transmission of synchronized sound and video took place on 13 June, 1925 when Charles Francis Jenkins sent a 48 line mechanical system image of film and sound five miles in a test transmission.
A person who uses sound waves to make images of the body is known as a sonographer or ultrasound technician. They operate ultrasound machines to capture images of internal organs and tissues for diagnostic purposes.
Ultrasound. Diagnostic ultrasound is the use of high-frequency sound waves to image anatomic structures and to detect the cause of illness and disease. Ultrasound moves at different speeds through the body's tissue, depending on the density of the tissue.
Luminous refers to something that emits light on its own, like the sun or a light bulb. Reflect means to bounce back light, sound, or heat off a surface, like a mirror reflecting an image.
The procedure involves the use of highfrequency sound waves (ultrasound). The ultrasonic waves echo off of the carotid artery to produce a two-dimensional image on a monitor.
High frequency sound waves are used in a medical imaging technique called ultrasound. These sound waves are sent into the body and bounce off tissues to create a detailed image of internal structures, like organs or a developing fetus. The echoes of the sound waves are then captured and converted into a visual representation on a screen, allowing healthcare professionals to see inside the body without the need for invasive procedures.
when the fetus kicks
Sound can first be perceived in the womb around 18-20 weeks gestation. At around this time, the developing fetus's auditory system begins to respond to sound vibrations, allowing it to detect sounds from the outside world.
It bounces sound waves into the womb. The sound waves are then bounced back again and the image that they produce by bouncing around the fetus is relayed and shown on a computer screen. As they sound waves can only bounce around objects they cannot creat colours hence it is in black and white.
You cannot convert an image to sound. It is because of the difference in the file formats of both.
18 weeks into pregnancy :)
3D ultrasounds work by sending sound waves down and around the fetus. The sound wave then bounce back up and are read by software which creates an image, because the sound waves go in more than one direction it allows the picture to be more enhanced and detailed than a regular 2D Ultrasound.
No. However, when the eyes of the fetus are developed and finally can open and close, they can see light. The fetus may even shield its eyes with its hands if you were to shine a bright flashlight directly into the mother's tummy! The fetus can also hear some things outside the belly once the ears have developed.

Yes they can see the fetus.
Echoes and reflections.
