The third type of fingerprint reader is called an ultrasonic scanner, because it uses high-frequency sound waves (ultrasound) to "map" your finger instead of light. If you have a new Samsung smartphone, you'll probably find it has one of these built under the display, which you can use ...

Do not eat for four hours before the HIDA scan. Water is okay. Eat a “fatty” meal the night before (e.g., drink a glass of whole milk). Is a gallbladder scan painful? A gallbladder ultrasound is a noninvasive and typicallypainless examination usedto diagnose conditions related to the...
I understand that you wish to remove the skull area in order to isolate the tumour from the MRI scans but are facing issues with it. To isolate and remove everything except the tumor (assuming the bright white spot) from the MRI image, it is required to focus on...
DICOM (Digital Imaging and Communications in Medicine) is a standard format for medical images and related data. DICOM files, commonly known as DCM files, store medical images such as X-rays, MRIs, CT scans, ultrasounds, and more. Along with the actual pixel data, DCM files may also conta...

CT scans for pregnant women pose no risk of injury to the baby. However, radiologists may recommend an ultrasound or MRI exam to avoid using radiation. The low doses of radiation used for CT scans have shown little-to-no harmful effect on human tissue, but a health care provider will rec...
Ultrasound scanner:An ultrasound signal is used to record the echo the fingerprint creates, as ridges and valleys create different echoes. This scanner does not need to be in direct contact with the finger to get a reading and also has the benefit of reading in a more three-dimensional manner...
Some of these techniques include things like X-rays, MRI scanners, CAT scans, ultrasound and so on. Each of these techniques has advantages and disadvantages that make them useful for different conditions and different parts of the body. Nuclear medicine imaging techniques give doctors another way...
