AEC maxed out: GE’s automatic exposure control (AEC) tools, SmartmA and AutomA, select tube current levels during an exam between minimum and maximum tube current limits based upon the patient habitus as interpreted from the last acquired CT localizer radiograph. If the noise index requested for an image is lower than is allowed by the maximum tube current, the AEC will choose the maximum tube current throughout the scan. This infrequent occurrence can happen due to patient positioning which increases patient dose [17, 18, 31, 32], improperly chosen or set-up protocol [21, 33], or large patient size. If a scan is maxed out in mA for the entire scan, then the average and the maximum mA values will be identical. In such a case, we classify the protocol as having either a manual mA technique or being “maxed out”. If the maximum mA and the average are not equal, then we classify the irradiation event as having utilized

Conductor – conductor is an object or type of material that allows the flow of electrical current in one or more directions. The electrons move easily to the other side, away from the object

The two types of electrical circuits are series and parallel. Series circuits provide only one pathway of current flow, while parallel circuits provide multiple pathways of current flow. Unfortunately,

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

Although Radiologic Technologist (R.T.’s) are most likely known as just someone who takes X-rays they do much more than that. They are responsible for setting up the x-ray equipment along with positioning a patient anatomically

As with any dental procedure, Dr. Thomas Peltzer will want to initially conduct a thorough examination of the wisdom and surrounding teeth. Panoramic or digital x-rays will be taken in order for Dr. Peltzer to evaluate the position of the wisdom teeth and determine if a current problem exists, or the likelihood of any potential future problems. The x-rays can also expose additional risk factors, such as deterioration or decay of nearby teeth. Early evaluation and treatment (typically in the mid-teen years) is recommended in order to identify potential problems and to improve the results for patients requiring wisdom teeth extractions. Only after a thorough examination can Dr. Peltzer provide you with the best options

X-rays may be invisible waves found on the electromagnetic spectrum which can almost make their known danger seem of little importance because our five senses cannot measure their activity, however x-rays must not be taken lightly. Radiologic Technologist must keep in mind the dangers and gravity of the force that they are working with on a daily basis. Patients should have the right to their own safety when undergoing a medical procedure that requires the use of x-rays. Radiologic Technologist are the ones responsible for upholding this safety. They can and must do this in variety of ways that include, making sure the patient is knowledgeable about the procedure, using correct collimation to the part under examination, and by shielding the

A scientist would need a glass tube with positive and negative electrodes. The tubes were called cathode tubes, and they were common in the late 1890s. The air leaves the glass tube, and a florescent glow is produced when a high voltage runs through the tube. The scientist needs to cover the glowing tube with a heavy, black paper or cardboard. Then the scientist will see the green colored fluorescent light illuminating from the box. This is known as the X-Rays which energizes the phosphorescent materials in the room. The newly discovered ray would pass through objects, and it can cast a shadow of most solid objects. The ray consists of electron passing through the matter underneath the cathode tube. It can pass through human tissues, but it cannot pass through bones and metal

This is a unit of measure of ionization in air, the quantity of radiation that produces one electrostatic charge in 1 cm3 of air. Radiation dose is the amount of energy absorbed by a tissue at a specific point. The rad is a unit of absorbed dose (the amount of energy absorbed by tissue) and is defined as 100 ergs of energy per gram of tissue (or rem). A localized dose of radiation is a rad of radiation to the localized area. Every gram of body tissue in that area absorbs one rad. When concerning total body dose in dentistry, the x-ray machine delivers a localized exposure with a single radiograph that results in a total body exposure approximately 1/10,000 of the facial exposure. X-rays have no effect on the nucleus of the absorbing atom, affecting only the atom’s orbiting electrons. Although the equipment and walls are receiving radiation in a dental operatory, they do not become

The basis of modern day electrical systems were all derived over a quarrel involving the light bulb, the electric chair, and a 28-year old Croatian immigrant.This dispute involved three of the biggest and most prominent names in the history of electrical engineering: Thomas Edison, Nikola Tesla, and George Westinghouse, who were all scientists and innovators who lived during the late 1800s. Edison and Tesla would get into a quite large argument over the best and most efficient kind of electrical currents. It would be Edison’s direct currents against Tesla’s alternating ones. This disagreement would go on to shape the course of electricity across the country. It would later be known as the War of Currents. The War of Currents had a great impact

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’
