Medical Equipment Advancements: The X-Ray Machine

One of the most common pieces of medical equipment and tests that almost every person has undergone at least once in their life has a unique history and purpose behind them. Almost every person has undergone an X-ray at least once in their life. Here is a look at the history behind the X-ray and how X-rays really work.

The invention of the X-ray is often considered an accident. Wihelm Roentegen was working around different types of lights and wavelengths and he helped to notice that a certain wavelength produced images that looked as if you could see the bones inside the body. After much research and development the process has become what it is known as today.

The way that an X-ray machine works is fairly complex and might be hard to understand. There is a pair of electrons that are contained within a glass tube. One part of the pair of electrons is heated up. When these electrons are heated it draws all electrons through the machine. The element is then sent through the body.

When the X-ray image is sent through the body the skin does not stop it from going through. Instead it goes into the body and denser objects like the muscles and bones will absorb the light. This allows the camera to pick up the image that health care providers use. The images are picked up in a similar technique to regular film cameras.

This X-ray process has become extremely popular over the years. X-rays are commonly used by doctor’s and health care providers to diagnosis broken bones, muscle problems, dislocated joints and torn ligaments. Dentists are also known to use X-rays to diagnosis problems with the teeth, gums and jaws.

Next Generation of MRI Machines Will Ease Patients Minds

An MRI has an important place in any hospital. It doesn’t use ionizing radiation like CT scans and so there’s much less chance of complications for patients. The MRI provides especially good imagining of different tissues and proves useful in brain scans, cardiovascular scans, and oncology. MRI machines are incredibly expensive. Traditionally insurance and federal funding have supported MRIs, but the Federal Deficiet Reduction Act has reduced payments for an MRI. This economic reality colors any institutions consideration in regards to an MRI. However, there are several different advances and avenues to consider in regards to MRIs.

The first question concerns the resolution of the MRI. Currently, there are both 1.5 and 3.0 Tesla MRIs. The 3.0 Tesla MRIs have a much higher imaging resolution. This allows them to pick up a wider range of phenomena when scanning the patient which will aid in diagnosis. However, they’re much more expensive and they’re currently all close bore which can cause discomfort especially to patients with claustrophobia or anxiety.

One can find a wide range of different models and advances when considering a 1.5 Tesla model. Some of the newest models can maintain the magnetic field even with an open side. This allows patients to have an open experience will still maintaining the imagining level. This level of comfort for patients might be worth the trade off in resolution especially if one can refer them to a nearby hospital with a more powerful MRI.

One should consider cost as well as comfort. A higher resolution MRI may garner referrals for difficult cases from other local hospitals and clinics even if they have their own. However, it might make sense to go with a cheaper and more comfortable MRI if the area is already saturated by a high level of high imagining MRIs. One should always factor in cost to the purchase of large equipment or it can quickly become a drain on the hospital or clinics finances and reduce resources for patient care.

Breakthrough in Medical Technology – Better Cardiovascular Disease Detection

A research study published In the Radiology journal issue of September 2010 has reported the development of a new medical technology that will help medical professionals diagnose cardiovascular diseases earlier than previously thought. The new cardiac imaging device developed by the Mount Sinai School of Medicine takes into consideration the coronary artery plaques that are rapturous using the multicolor CT (Computerized Tomography).

How does this medical technology work?

70 percent of heart attack cases are due to the atherosclerotic plaque ruptures. The ruptures take place when the “good” cholesterol (HDL) is drawn towards the plaques and because of their vulnerability; they are removed from the artery wall. What the Mount Sinai team of researchers did was to harness the HDL with tiny gold particles. The researchers then injected the captured HDL into mice and when the CT scanner was used, the HDL particles could me easily seen on the image screen. This was helpful in locating the position of the vulnerable plaques and thus, by this technology, radiologists can quickly detect cardiovascular problem onset.

If the multicolor CT medical technology is made available, it will help better the diagnosis process and ensure medical help to every patient. Mount Sinai researchers believe that the same technology could be also used for imaging other diseases and biological problems such as kidney diseases, bowel problems and several types of cancer. David Cormode, the lead research author of the work commented that the technology will provide for a “significant unmet need for imaging technology that visualizes plaque vulnerable to rupture”.

If this imaging medical technology can be used for early cancer detection, it will undoubtedly be a boon for people. We know that cancer is most of the time diagnosed in the last stage, which significantly decreases the chances of survival for patients and leads to costly medical services. If the disease is detected at the earliest, the person and medical professionals will have time to use the correct combative measure and thus, save precious lives.

Common Medical Technology Practices

Diagnosis of diseases and efficient medical care is incomplete without better medical technology practices. These technological advancements not only help save time due to their working efficiency, they are responsible for providing excellent medical facilities. In the last decade or so, there has been immense advancement in medical technology. Some of them are explained below in brief:

Bar Coding

It is a medical technology that allows for tracking the medications by printing unique bar codes at the back of each medicine. This way, not only the manufactured medicines are recorded but also there is reduced cost of lost medications.

Infrared Technology

It is the system of tracking the medical supplies and personnel details within the hospital. Each member of the staff are given infrared badge and sometimes, if the need be, patients are also bound in infrared sensors to help track them. Moreover, since the supplies are marked too, there is less chance of medical supplies theft.

Magnetic Resonance Imaging (MRI)

This medical technology allows for disease diagnosis by using visual cross sections of the human body. The MRI machine creates a 3-D image by combining the water molecules present in the body with the radio waves that is turned into cross sectional images.

Computerized Tomography (CT)

A powerful computer program and rotational x-ray machine is used to create the CT scan. Unlike the traditional x-rays, the CT scan’s are more detailed, providing an intrinsic image of the body internal structures and organs. Usually, the CT scan is advised for locating internal injuries, muscle or bone disorders, and location of tumors.

Positron Emission Tomography (PET)

The PET medical technology scans are used for molecular detection of brain disorders, heart related problems and cancer diagnosis. The areas in which higher chemical activity is detected, the radioactive material accumulates there and the image is shown in the scan. Both the CT scan and PET scan are used together for disease diagnosis.
