Major Types of Medical Imaging Equipment

Many of us are familiar with the most common type of medical imaging equipment, X-rays, but did you know that there are many different types of imaging machines that help doctors diagnose health issues? The advances in medical imaging equipment are amazing, and an example of some machines you might not know as much about are electron microscopes, magnetic resonance imaging (MRI's), ultrasounds.

Electron microscopes are a great tool for physicians and clinicians to get a better sense of what's going on at the basest level. Because electron microscopes can magnify at a level of 2,000,000 times, they are used in anatomic pathology, which identifies orgnalles within a patient's cells. Although immunhistochemistry, a new method has taken some of the focus off of electron microscopy, this essential medical imaging equipment is irreplaceable for the identification of immotile cilia syndrome, the diagnosis of kidney disease, and many other things.

Most of us have heard of MRI's, but what are they exactly? Simply explained, a magnetic resonance imaging scanner uses the power of magnets to polarize and excite the hydrogen nuclei in water molecules that are present in all human tissues, and this then produces a detectable signal which can be interpreted to create images of the body. This type of medical equipment is especially useful for identifying soft tissue problems, such as those in the joints or the brain, because X-Rays work more specifically for harder tissues like bone.

Another medical imaging machine you may have heard of are ultrasounds, especially for pregnant women looking at their unborn babies. It is have very broad uses in medicine however, including imaging the abdomen, heart, breast, muscles, tendons, arteries and veins. How does it work and what do doctors use it for? Medical ultrasound instruments use high frequency broadband sound waves in varying degress in the megahertz range to produce 3-dimensional images. These ultrasound images do not have the anatomical detail of images produced by an MRI machine, it is widely used because it is appears to not have any adverse side effects and is safe to use. Ultrasounds are also relatively inexpensive as opposed to catscans or MRI's, so they continue to be a staple in medical offices and hospitals.

These are just three examples of the medical imaging equipment available today. Technology continues to advance and there are sure to be many more exciting developments to come in the world of medical equipment and supplies, and you can expect the level of healthcare to commensurately increase.

Is a Med Tech good if you like microbiology.?

I like cells, bacteria, microscopes, microbiology labs, etc. Will that be a decent part of my job if I do medical technology, or is it not like that at all.

Yes! Medical Technologists that work in microbiology culture, analyze, identify and perform susceptibility testing on bacteria, fungi, and mycobacteria, and also identify viruses and clinically relevant parasites.

The field of medical technology also encompasses hematology, chemistry, genetics, immunology, immunohematology (blood bank), and histology among others. Working in most of these departments involves use of automated instruments and sometimes mechanical troubleshooting. Areas like chemistry are extremely automated and the work tends to be repetitive and routine. But microbiology is very different! Microbiological testing requires more pre-analytical setup (specimen processing and culture planting) and a lot of critical thinking. Because of the nature of working with living organisms, microbiology labs cannot be automated to the same extent. So, most microbiologists find their work very fulfilling, and enjoy the "hands on" experience.

I work as an MT in a hospital microbiology laboratory and I would have to say I would not trade in my career very easily. There is a growing shortage of MTs due to a retiring majority that belong to the baby boomer generation. So, new graduates should have NO triouble finding employment. ALSO, the two major certifying bodies (ASCP and NCA) have just agreed to merge into a single agency that is expected to bring a lot more recognition and respect to the field.

With a bachelor's degree in the biological sciences and the appropriate prerequisites you can apply to any school of medical technology (internship) that has a "4+1" option - the four refers to an already obtained degree plus a 1 year clinical internship. A lot of MT interns in the medical technology degree program apply as "3+1" students and use the internship as their senior year. The program prepares you to sit for and pass a certifying examination in medical technology/clinical laboratory science through either ASCP (The American Society of Clinical Pathology), NCA (National Credentialing Agency for Laboratory Personnel) or AMT (American Medical Technologists). Check with your local college, university or hospital to find the best MT school in your area. See the link below for the different qualifying routes for the ASCP certification (ASCP is the most widely accepted in the U.S.).

Hope this helps! Good luck

'Micro-Ear' will Listen to Living Cells
Follow Israel news on and . (IsraelNN.com) A new development, the “micro-ear,” will soon be able to help scientists listen to the tiniest events, exactly as the microscope reveals those things that otherwise would appear to be invisible.
