Cranioplasty is the method of treatment of skull defects; it is required to protect the underlying brain, correct major aesthetic deformities or both (Pompili et al., 1998). Today, three-dimensional (3D) models of anatomical structures can be constructed based on anatomical information from scanning data coming from computerized tomography (CT). Magnetic resonance imaging (MRI) data is used to 3D modelling of soft tissues and computerized tomography (CT) for Hard tissues (i.e. bone) of the human…

There seem to be numerous things that are specifically for women, whether pleasant or not. It appears as though women require a little extra work in a few regions. One example of this very thing, is a minor surgical procedure known as a Colposcopy. A colposcopy is a procedure done on women to better examine the cervix, vagina, and vulva. This is generally done if a pap test or pelvic exam came back with any abnormalities. It can be used to diagnose and analyze numerous conditions such as:…

During an exam, ultrasonic beams propagate through a patient’s tissue by means of the transducer. As the beam propagates, there is a loss of energy through absorption, reflection, and scattering. This loss is displayed in the image as shadowing. To start, shadowing may result due to the absorption or reflection of most of the energy. The degree of shadowing is dependent on the structure and size of the object that’s blocking the ultrasonic beam and its relativity to it. Shadowing is seen when…

The experiment investigates a GM tube and a GM counter and the relationships of radiation. The experiment uses a GM tube to detect radiation coming from a source. This is done by the decay particle ionizing and causing the charge to build up in the tube, which is discharged and the discharge is counted by the counter and added to a display. The GM tube must be calibrated at the best voltage so that the count rate is independent of the voltage. A test was done to find this value by changing the…

disruption, one never knows when evil aliens could be to blame. NASA HOPES TO UNDERSTAND VIOLENT BLACK HOLE NASA doesn't quite understand what caused the X-ray flares near the black hole just yet. However, they do know that when a black hole occurs, it's possible to detect its echo a couple minutes later. This is done with a technique called X-ray reverberation mapping. It's been used in the past but this is the…

The CT scanner Depends upon several steps:- 1-The x-ray tube and detector transverse (scan) the object. 2-The radiation beam passes through the object and is attenuated. The intensity of radiation beam from x- ray tube and transmitted beam both are detected by suitable detectors. 3-The transmitted beam and the references beam are both converted into electric signals. 4-These output current signals are then converted into digital form by analog –to-digital converter. 5-The digital data are…

Risks and Benefits of Diagnostic X-rays General Purpose: To inform. Specific Purpose: After hearing my speech, my audience will know more about the risks and benefits associated with diagnostic x-rays. Thesis: Medical benefits of diagnostic x-rays outweigh any slight risks. Introduction Open with impact: It’s all around us. You can’t feel it, you can’t see it, but it’s here nonetheless. I am talking about radiation of course. Radiation is energy that comes in many forms and is all around us, all…

WHIRRR… The x-ray machine did a thorough scan on my hurting right elbow. When I saw the machine’s data, I threw up a little in my mouth. The results were not pretty as it looked like something crawled out of a dumpster and got run over. My parents had always told me to be careful, and I wished I had listened to their warnings. Looking back, I saw how this all started because of a table that decided not to break. “I’m home!” My voice echoed throughout the house as I flew inside. I had just hopped…

Most Technicians work in hospitals running MRI scanners and taking X-Rays of patients. Depending on the hospital that I would be working at, I could be on call meaning that I could be paged to come into work at any moment in time. Although this can cause a lot of conflict with friends and family, emergencies outweigh most…

X Rays are used for medical imaging and are given off by stars. The detectors vary in shape and function but all do the same job of identifying the bone structure. In 1901, when this was invented, it was a great contribution to treating illnesses. At one time, people tried to use X Rays to remove unwanted hair. Later the FDA banned it because it resulted in a serious illness, which was cancer…
