Several imaging techniques have been invented over the years to be used to image the body. Some good examples include x-ray, CT scan, digital x-ray, MRI, and ultrasound. Each of these methods offers various advantages and disadvantages that make them suitable for use in different situations. For instance, x-ray is excellent for imaging bones and other hard tissues in the body. When in need of 3d ultrasound Dallas should be visited.
On the other hand, MRI is suitable for imaging soft tissues because it gives a high level of accuracy. Ultrasound on the other hand is a very safe imaging method that is often used to image infants in the womb. This method of imaging makes use of high-frequency sound waves to create images of body organs. The waves are sent into the body using a handheld transducer.
These waves usually generate an image on the screen when they bounce off body organs. The sound generated is referred to as ultrasound because it cannot be detected by the human ear due to its high frequency. The frequency usually ranges between 2 and 18 megahertz. Images generated by higher frequencies are usually of higher quality.
However, higher frequencies present one major shortcoming where they are more readily absorbed by the skin and other tissues. This usually prevents the sound from penetrating deeper into the body. On the other hand, lower frequency sounds are able to penetrate deeper into the body to produce images of organs seated deep into the body. However, the one shortcoming that is associated with them is that they form images of inferior quality.
The term sonography is at times used to refer to ultrasound. The process produces images which are known as sonograms. Medical professionals such as cardiologists, radiologists, and sonographers can perform sonography. However, sonographers normally carry out the process in health facilities where tasks are divided and there is specialization of tasks. Sonographers are usually trained specifically to handle machines used in ultrasound.
Once the sonographer produces the images, they are transmitted to a cardiologist or radiologist to be interpreted. In some cases the practitioner that does the interpretation of the images may be located at an offsite facility. In this case, remote radiology is normally employed. Remote radiology makes use of high quality technologies that use high speed internet connection. The sonograms get encrypted for privacy and sent over to the interpreter.
The use of sound waves means that ultrasound scans do not use radiation, which makes them very safe. In fact, they are so safe that they are routinely used to evaluate fetal development. They are also used to detect problems in vital internal organs such as kidneys, abdomen, heart, and liver. The use of radiation-based technique to image these organs can cause more harm than good.
When used for evaluation of fetal development, this method is used at different stages. It can also be used to determine the gender of the baby before birth. No risks have been associated with the use of this method to image fetuses in the womb.
