Throughout childhood and into adolescence having skinned up knees and injuries was all part of growing up. If we fell and injured ourselves‚ we would get right back up and move on with our lives. In some cases children may view having a broken bone as a source of pride. However for older adults the dangers of falling have real consequences because if a bone is broken it can range anywhere from a temporary inconvenience to a complete loss of independence. The elderly also have a higher chance

in the thoracic cross-section imaging‚ chest radiography remains the main diagnostic concept applied in dealing with pulmonary diseases. It is the frequent diagnosis performed for patient suspected of thoracic abnormalities. Since the discovery of X-ray‚ much technological advances have been made to improve chest radiography. Progresses in film based imaging have led to development in excellent screen film systems that are designed for chest radiography. More recent advancement in computer and electronic

The ejected electron is known as a recoil electron which is scattered in the forward direction. The photon has a longer wavelength than the incident photon due to loss of energy. Pair production never occurs in diagnostic radiography but does occur in radiotherapy radiography as the energy required for it to be initiated is 1.02 MeV. This process is inversely proportional to energy. A positron and a negatron are produced; the positron is annihilated when it collides with an electron. Electrons are

Standard Operating Procedures Radiology 1. PURPOSE: a. To provide maximum quality radiographs in an efficient amount of time. b. To establish responsibilities‚ procedures‚ policies‚ and techniques which prevent excessive radiation exposure to patients and staff. c. To set guidelines to be followed for checking radiology systems performance and maintaining optimum image quality and equipment safety for the technologist who operate these systems and the patients as well

The beginning of fluoroscopy can be taken way back in the 90s when there wasn’t much technology. This was all discovered by Rontgen‚ who noticed a fluorescing screen during the exposure to what was later called x-ray. Back then many people where wrong after coming up with conclusions that fluoroscopy would completely replace x-ray after knowing that in fluoroscopy there was movement available in the process. In fluoroscopy‚ a machine is used. One that can use either a continuous beam or it can do

San Francisco‚ January 21‚ 2014 - The global market for portable X-ray and CT scan devices is expected to reach USD 8‚408.0 million by 2020‚ according to a new study by Grand View Research‚ Inc. Rising demand for bedside imaging‚ home healthcare and the growing use of CT scan devices for anatomical confirmation and to assess the accuracy of medical implants during and post interventional medical procedures are two of the most significant growth drivers of this market. The market will also be driven

main imaging techniques used in radiography. For the purposes of this essay‚ we will look at conventional x-rays and diagnostic ultrasound. Conventional x rays are non-invasive diagnostic techniques that are used to capture images of the body’s organs and bones. Diagnostic ultrasounds are high frequency sound waves to create an image of soft issues in the body such as muscles‚ joints‚ and internal organs. As examined below‚ while both are used in diagnostic radiography‚ they have extremely different

This allows organ function to be seen‚ e.g. in GIT studies. To examine blood vessels‚ contrast media can be injected straight into the patient’s bloodstream‚ e.g. in angiography 7) Outline the difference between projection radiography and fluoroscopy Projection Radiography: In a regular x-ray‚ single radiographs are taken of a region of interest. Collimation is square or rectangular‚ and the image is not inverted (bone shows up white‚ air shows up black). Fluoroscopy: In fluoroscopy‚ the x-rays

advancing technologically every year‚ the workload is escalating and also sometime leads to workforce shortage due to poor management and not having a proper strategy in place. (Lau‚ 2009). Most hospitals have now changed to digital or computed radiography‚ which are much faster imaging modalities as compared to the traditional conventional film and paper imaging. These hospitals can increase their patient throughput by simply improving their operation rather then to increase its physical capacity
