How Does Technology Change The World Changing Technology Work?

Magnetic Resonance Imaging (MRI) in the 1970s to 1980s to present day. Has served as a medical imaging technique used in radiology to form detailed pictures of the body for both health and disease. In the MRI scanners, there are strong magnetic fields, radio waves, and field gradients in order to generate images of the inside of the body and appear on a screen. MRI and X-rays are not the same. MRI scans take more time, are louder, and usually require that the body goes into a narrow tube. While X-ray scans take less time, aren’t really loud, and don’t involve a narrow

Technology has changed drastically from the 1970s to now. We have exceeded what most people back then could ever imagine. The technology used in schools, homes, and in public places has evolved into technology that makes the “cutting edge” technology of the 70s look very simple. Things such as the personal computer, the cell phone, electronic games, TVs, and even watches have changed completely. The ways that they have exceeded expectations is truly unbelievable.

What would Wilhelm Roentgen, the father of X-ray, say about the technological discoveries in radiology today? Since the start of X-rays in 1895 significant advancements have revolutionized the field of radiology. One illustrates how different scanners have improved, in addition how picture archiving communication system can assist doctors, and finally the outlook on the future of radiology.

Furthermore, X-ray of higher energy than required for imaging is used for radiation therapy. The radiation therapy makes use of ionization radiation (and no images) for the treatment of diseases, such as

- Even though the X-ray expose patient to harmful radiation it is used to see inside the human body and diagnose broken bones, gallstones and later tuberculosis.

All of our X-rays are digital, using 90 percent less radiation to get an even more accurate image of your mouth. And we use ViziLite Plus, which uses ultraviolet light to help detect signs of oral cancer.

These images call for up to 90% less radiation than with standard film type x-rays. Instead of making use of the traditional silver-oxide x-ray film that must be formulated and then fixed in caustic and ecologically harmful solutions, the new system calls for pictures by way of a small digital sensing unit and it then immediately sends a Image of the tooth on to the video monitor in the treatment room. Therefore, we can easily see your teeth and surrounding components Instantly. Not only does the new digital x-ray do away with the typical wait for x-ray film to be prepared, but it also is highly sensitive, so that patients are exposed to even less radiation than with conventional x-rays.

X-rays have numerous different effects on the tissues of the body, depending on the time of exposure and energy of the X-ray photons. Best contrast between different tissues is when the photon energy is about 30 keV, for diagnostic purposes. Resulting in the photoelectric effect dominating at this energy. The tissues absorb X-rays and electrons are released. The X-ray absorption depends on the number of protons in the nuclei of the atoms encountered. A high number will attenuate the beam, producing a strong x-ray shadow, enabling for a high quality image of

The backscatter X-ray machines are much weaker than the machines that are being used in the hospitals by the doctors. The rays of backscatter X-ray machines do not go through the flesh of the body. It will only penetrate the clothing and almost an inch into the body where the tissues in the body will scatter and reflect the rays back to the sensor.

A 14x17 cassette was used. Dependent on body habitus it was either placed crosswise or lengthwise. A grid is used on chest x-rays to reduce scatter and improve image contrast.

A focus on the equipment is most important as it relates to the human-machine interaction (we learnt about this in the HCI project in class, as well as in lab). That is to say, the need is not necessarily for more powerful x-rays but rather x-ray imaging that facilitates screeners’

(Long, Smith, Rollins, 2016, pg. 5). Since it is a static single dimensional image depicting a view as if you were looking through the body usually more than one x-ray is prescribed. The pros of using plain x-ray for an examination is that it is cheap compared to other modalities. It is the most common exam used in diagnostic imaging, and it is often used as a preliminary exam to determine if more extensive testing is necessary. Just like CT patients are exposed to ionized radiation but at much lower doses than a CT scan, and patients can also have a negative reaction to contrast or dyes which are occasional intravenously injected to improve the image

Fluoroscopy uses real-time x-rays that create a dynamic image. The new fluoroscopy machines give us quick and simple techniques that enhance the navigation throughout the tissue. The physicians use the C- Arm to visualize and guide them throughout the procedure. Depending on the age of C- Arm there are some that can take CT images “CT fluoroscopy has an Application for biopsies and CT interventional procedures, such as abscess drainage when the availability of real-time facilities accurate placement of needles.” (Bontrager and Lampignano pg711 2014) . Other fluoroscopy units can take three-dimensional images using x rays “CBCT is an advanced imaging capability that uses C-arm flat-panel fluoroscopy systems to acquire and display 3D images” (Lerardi and Duka pg111 2015) New technology have a smart handle that makes it easier to get better positioning. According to the article Coming to a radiology department near you: the latest and greatest in technology “A new double-sliding C-arm on Toshiba Medical’s Infinix –I Sky+ will allow clinicians to position the detectors for 210 degrees of anatomical coverage on both the right and left side of the patient.” (Massat and Jalkiewicz pg35

Well, Wilhelm Conrad Roentgen has created the first invention that can do this and has called it the X-Ray. He has called it the X-Ray because he still hasn't identified the ray that makes this invention work. When he invented the X- Ray he was not trying to make something that can see into someone's body he had made the X-Ray by accident. The X-Ray looks past the tissues and shows bones and metal in a person's body.This is something that many people thought was unbelievable when Wilhelm Conrad Roentgen showed off his new invention. This technology is still in its early stages but has already been being used on the battlefield to help doctors find shrapnel and bullets in the wounded soldiers body. This will help doctors know where they half to surgery at. Looking forward this technology is something that will help save lives and have a major advance in medical technology. This technology is still far from being released to the public for public hospitals to use but this is a step forward. This is definitely something that will change medicine for the

Medical imaging such as the x-ray work by shooting a x-ray beam at your body and on the other side of you they are detectors and it detects those waves which result in an image which ever part is not detected is your image. Many people may think a x-ray is a machine and that is true but a actual x-ray is a
