A Short Note On The Inverse Square Law

Radiologic technology is a satisfying and rewarding career. It is a technical and refined science. As a radiological technologist, there are many essential duties and responsibilities that have to be fulfilled in order to be a good one. First of all, radiological technologists have to maintain a well-mannered and professional behavior when gathering information. They have to assure their patients that they are in good hands therefore; they give patients the uppermost quality of care and services. Second of all, the main responsibility of a healthcare provider is to keep all knowledge of a patient’s health record confidential or secluded. That means radiological technologists cannot talk about patients at home or with friends and classmates

There are two very divergent viewpoints across the medical provider landscape as to whether radiological testing is used too much or not enough. The basic equation comes down to a balance between being sure that certain conditions and disorders are not in play and not wasting time/money and/or exposing the patient to potential harm due to the fairly dangerous nature of being exposed to too much radiation.

e. Some radiologist also treat cancer using radiation; others do surgeries

Advances in both radiography and radiation treatment keep on advancing and get to be more sophisticated. Cases incorporate digital subtraction angiography (DSA) in which, apparently, there is the potential for more prominent inclusion by radiographers and by radiation therapists in image guided radiation treatment. Looking even to the moderately later past underscores the degree to which change is happening in the radiography and radiation treatment work environment. Case in point, ten years prior it was radiologists who embedded cannulas for CT patients (AIR 2014, 1). Presently radiographers and attendants attempt the assignment. In private radiology hones, Australian radiographers now consistently embed central lines and do feature joint, shoulder, arm, and tendon infusions under supervision.

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

Radiation therapy can be used anywhere in the body to treat any kind of cancer. Depending on what type of radiation therapy, it can have some side effects. The most common ones include fatigue, hair loss near the treated area, and skin darkening in the area exposed to a beam of radiation. ("Radiation Therapy for Cancer,” 1) There are also safety concerns that patients have when they are treated with radiation therapy. Many people that receive radiation therapy treatment, worry about exposing family and love ones to radiation, as well as the side effects. Radiation effects on the normal tissues are divided into acute and chronic effects (Schreiber). Acute effects occur during the course of therapy and during the post therapy period (approximately 2-3 weeks after the completion of a course of irradiation) (Schreiber).

One of another main reason for all the irregularities during the procedure occur mainly due to the confusion of communication between the radiographer and the surgeon because of a formal language is not being used in order to operate the fluoroscopy (Suhm et al., 2003 ).This creates a confusion and loss of crucial time which eventually leads to numerous position adjustments, while doing so the radiographer had to expose the patient several times before the desired position can be obtained which can prove to be serious threat depending upon the nature of patient as exposure to radiation differs depending upon the nature and status of a patient.

In the mid-1960s, an era when Technology was rapidly advancing, it became important for all the Radiology professions governing bodies, ARRT, ASRT, and ACR, to increase the standards and level of training for Radiology professionals (Phillips, 2010). This advancement began to make the term “Technician” quite limiting. So, with more emphasis on professionalism and education, the term “Technologist” was born because it accurately reflected the Associate Society of Radiologic Technologist (ASRT) membership (Phillips, 2010). This development and classification also came with additional responsibility, where all Technologists have to adhere to the standards created by the ARRT.

In the Nuclear Medicine department, the two most common procedures performed are bone scans and VQ scans (ventilation/perfusion scan). During a Nuclear medicine procedure, the patient is either injected or inhales radioisotopes, which then causes the patient to become the source of radiation that is picked up by a gamma camera. A VQ scan is a two phase scan that requires the patient to be injected with a radioisotope and inhale a gas infused with radioisotopes. This scan is used to determine the blood and air flow of the lungs and detect possible pulmonary emboli. The radioisotopes used for this exam include radioactive Xenon gas and technetium. As for the bone scan the patient is

X-rays are electromagnetic waves of very short wavelength and high frequency, in the range 0.001nm to 10nm. Due to their high frequency (therefore meaning high energy), x-rays penetrate flesh and may cause ionization of atoms they encounter. The body tissue absorbs energy and the intensity of the beam is reduced when x-rays pass through the body. Denser material, such as bone, absorbs more X-radiation.

If you have thought about becoming a Radiologic Technologist, someone who performs imaging examinations, but do not know if it is the right choice for you. This paper will inform the reader as to how to become a Radiologic Technologist, their job description, ranging from the work settings to the kind of patients they deal with, some of the challenges and rewards, including their salary as well. At the end of this paper you should be able to make up your mind on becoming one or not.

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

In addition, Interventional radiologists may sub-specialize further so that they only treat abnormalities of the brain. And the Radiation oncology uses radiation to treat diseases such as cancer, using radiation therapy. These specialists are not called radiologists, but radiation oncologists, even though they belong to the Royal Australian and New Zealand College of Radiologists. These three fields are alike in that they all use a form of imaging device in order to help them to treat and interpret treatment for the patient. The biggest contrast between the fields of Diagnostic Radiologist, Interventional Radiologist, and Radiation Radiologist is how they use the tools of their trade. Each of the fields will use the imaging devices in a different manner for their treatment of the

Patient Care is a very broad and widely talked about topic in the health care field. There are things concerning today 's medical imaging technologists, mainly the radiographic technologist that will be touched upon throughout this

When assisting the patient, the radiographers have to make sure they provide radiation safety not only for the patient but also for themselves. There are many different methods to providing safety. With the equipment and radiation dosage, highest KVp and the lowest mAs is used to provide the minimum amount of dosage required for the procedure. Furthermore, safety can be provided by reducing the amount of rime in radiation area, by putting as much distance between you and the radiation source as possible. When performing a portable examination stand at least six feet from x-ray source and wear a lead apron. The patient should remove any jewelry or metal accessories that may interfere with radiation procedure and both the technologist and the patient needs to wear protective lead shields for example lead gloves, aprons, skirts and thyroid shields to protect the other body parts from the radiation. It is advised to also always wear monitoring device at collar level. Lastly, the technologist uses immobilization devices to hold the patients when needed.
