Types of Medical Scanners - Medical Imaging

medical imaging

Here is a straightforward definition for medical imaging - it is the art of establishing impressions of the organs in a human being with the intention of studying them in detail. With the help of the technique and the associated machinery, a qualified radiologist will be able to conduct in-depth examination of the organs located within the body. One must understand that such medical scanners have immense relevance and play a very active part in determining various medical complexities. Doctors usually diagnose different illnesses and ailments using the images created by these medical scanners. Once they are aware of the malady, they can suggest suitable remedial procedures so that the affected can avail timely curative assistance.

So, what are the various kinds of medical imaging techniques available on this day? We will start with fluoroscopy. There was a time when the doctors were satisfied with the static images of internal organs (such as x-rays). Using a fluoroscope, the radiologist will be able to capture real-time, moving images of the organs. Magnetic resonance imaging or MRI is another form of medical imaging technique that utilizes a set of powerful magnets to create impressions of the internal organs.

I am certain that at least a small share of the readers might have already heard about nuclear medicine. Injecting the body with isotopic or radioactive materials (which are relatively harmless) to the body and studying the various organs with the help of suitable machinery - all these constitute nuclear medicine! Photo-acoustics is widely deployed in photo acoustic imaging machines. The underlying paradigm is simple - the affected part of the patient will be subjected to a series of laser beams. The body cells will imbibe these and produce heat waves, which are subsequently captured to generate an image of the emitted surface!

Breast thermography is a form of medical imaging technique characterized by the use of digital infrared imaging procedures. Although it was initially used to study the effects of cancer cells and growths on the breast, it is now utilized to generate images of the internal body organs, specifically the nerve endings and the blood vessels. Computerized tomography is an additional form of medical imaging. You might have already heard about complicated techniques such as CT scans. A disadvantage of this form of imaging technique is the generation of two-dimensional images. CT scans of the organs would enable physicians to diagnose advanced stages of cellular damage.

Across the globe, other kinds of medical imaging techniques exist in the form of ultrasound. Waves that have high frequencies are subjected into the body part to produce a three-dimensional image. The technique will enable a gynecologist to learn in depth about the developmental stages of a fetus. Medical imaging techniques, when used in an appropriate manner can aid the medical industry immensely. Misuse and abusing of these technologies are quite common nowadays, which is a reason why a lot of people opt for alternative medicine or even whole medical systems. For instance, the widespread usage of ultrasound imaging led to a sharp rise in the number of abortions, especially in the developing countries.
