New Technology
The technology that I have selected to discuss is handheld radiological monitoring. There are several new equipment models being marketed. One of the most recognizable and well-respected names in radiological monitoring is Canberra. One of Canberra’s latest offerings for handheld devices is the Radiagem™ 4000. The device provides the capability of monitoring dose rates and contamination levels. There are a variety of probes available for use with the meter itself. The unit is waterproof and lightweight.
The Radiagem™ 4000 takes radiological measurements through an internal, energy compensated, Geiger Mueller detector. Through the use a various external probes, contamination levels can be quantified and readings can be recorded. The probes can be added or removed while the instrument is turned on. The external probes can be calibrated independent of the meter.
What does it do?
The Canberra hand held survey meter can be used to measure levels of transferable contamination, establish working dose rates and perform isotopic analysis. When performing surveys of radiological areas, it is important to gather data quickly and accurately. Modern survey meters allow for quick measurements of transferable contamination levels. Dose rates in work areas can be established for the protection of workers and to identify changes in conditions.
The radiation level that a worker has been exposed to is called their dose. Radiation dose is measured in rem. Merriam-Webster Online Dictionary (2010) defines rem as “the dosage of an ionizing radiation that will cause the same biological effect as one roentgen of X-ray or gamma-ray exposure”. What this means is that early radiation researchers found a way to equate the level of radi...

the effective doses from diagnostic CT procedures are typically estimated to be in the range of 1 to 10 mSv. This range is not much less than the lowest doses of 5 to 20 mSv estimated to have been received by some of the Japanese survivors of the atomic bombs. These survivors, who are estimated to have experienced doses slightly larger than those encountered in CT, have demonstrated a small but increased radiation-related excess relative risk for
The conversation around the rising costs of health care continues to be a high priority topic of discussion from consumer all the way up to the government. There are many products and services that contribute to the rising costs, as well as some responsibility left to practicing providers who choose to use high dollar radiology services for patient care. Ionizing radiation has been used for more than a century, however, this evolution or radiology services into widespread diagnostic and therapeutic uses has resulted in a significant increase in the population’s overall exposure to radiation with the potential to increase the risk of cancer (Amis & Butler, 2010). Examples of high dollar radiology services are services like Magnetic Resonance Imaging (MRI), Computer Tomography (CT) scans, and Echocardiograms. These services allow physicians t...

The team includes a radiation oncologist, radiation physicist, dosimetrist, radiation therapist, and a radiation therapy nurse. Each member of the team has a specific role in the treatment of each patient. “The radiation oncologist is a doctor specially trained to treat cancer patients with radiation.” (American Cancer Society p. 4) The oncologist will work with the dosimetrist to determine the plan for treatment. “The radiation physicist is the person who makes sure the radiation equipment is working as it should and that it gives you the dose prescribed by your radiation oncologist.” (American Cancer Society p. 4) “The dosimetrist is supervised by the radiation physicist, this person helps the radiation oncologist plan the treatment.” (American Cancer Society p. 4) “The radiation therapist is the person who operates the radiation equipment and positions you for treatment.” (American Cancer Society p. 4) Every member of the team is important to ensure the treatment is delivered safely and effectively as
As a starting point in CT diagnostic imaging the form of radiation used to provide an image are x-rays photons , this can also be called an external radiation dose which detect a pathological condition of an organ or tissue and therefore it is more organ specific. However the physics process can be described as the radiation passes through the body it is received by a detector and then integrated by a computer to obtain a cross-sectional image (axial). In this case the ability of a CT scanner is to create only axial two dimensional images using a mathematical algorithm for image reconstruction. In contrast in RNI the main property for producing a diagnostic image involves the administration of small amounts of radiotracers or usually called radiopharmaceutical drugs to the patient by injection or oral. Radio meaning the emitted of gamma rays and pharmaceutical represents the compound to which a nuclide is bounded or attached. Unlike CT has the ability to give information about the physiological function of a body system. The radiopharmaceutical often referred to as a nuclide has the ability to emit ga...
The Atomic Energy of Canada Limited (AECL) created the Therac-25 radiation therapy machine (Death and Denial). The major innovation of this machine is that it was much more computer-controlled than the previous machines of its kind. This enabled technicians to spend less time setting up the machine and more time working directly with patients. The reduced setup time also increased the number of patients that were able to be treated in one day (ComputingCases). Patients undergoing treatment from the Therac-25 are in communication with the machine operator (located in a separate room) through AV monitors (Death and Denial).

Radiologic Technologists use radiation to produce images of tissue, organs, and vessels that make up the body, as well as cancer, tumors, broken bones, and tumors (Cape Fear Community College). If a person is in the medical imaging field to become a Radiologic Technologist to help people, this part of the job is what grabs their attention, because as soon as they find these problems they omit the images to a doctor that helps take care of it. Radiologic Technologist is a branch of Health Science Cluster Diagnostic services pathway (OkCollegeStart). When a person’s knows where their career choice starts it helps get a better overview of where to start and helps get them where they want to be. Radiologic Technologists review and evaluate developed x-ray, videotape, or computer generated information to determine if images are “satisfactory for diagnostic purposes” (OkCollegeStart). Persons who are more technology driven are attracted to this career because of the technology a person gets to use and process. Radiologic
When taking a radiograph there are some precautions that can be taken to reduce some of the radiation that can be exposed to a patient, what would be used on all patients is call a lead apron and thyroid collar, these aprons are used to protect the patients that may be a bit more radiosensitive and also may give the patient a little of reassurance that they will be protected. “Radiosensitivity is the relative susceptibility of cells, tissues, organs, organisms, or other substances to the injurious action of radiation.”
...why does the technologist step behind a shield to prevent exposure to themself?" The radiation dose for each exam is relatively small, but over time, the dose can add up. There are many state and federal regulations limiting the total radiation dose that may be received by people working with radiation. To comply with those regulations, the technologist must follow strict precautions to keep their cumulative exposure to a minimum.
Radiation therapists work closely with patients to fight cancer. According to Health Care Careers, Oncologists, Dosimetrists and nurses are some of the professionals that a radiation therapist works with while caring for a cancer patient. This group of professionals will determine a specialized treatment plan. The first step usually includes a CT scan performed by a radiologist to find the exact area that needs to be targeted with x-rays. Next, the therapist uses a special machine that emits radiation called a Linear Accelerator. They use this machine during a treatment called external beam therapy. During this process, the Linear Accelerator will project x-rays at targeted cancer cells or tumors. Another therapist will be in a different room monitoring the patient’s viral signs until the procedure is over. The external therapy l...
Modern medicine is capable of treating a tremendous range of human disease and injuries, but the usefulness of all medical specialties depends on accurate diagnosis. Virtually every conceivable medical specialty relies on radiological technologies to provide formal diagnoses, making radiology one of the most important of all medical specialties. Radiologists enjoy some of the best working conditions in modern medicine and typically experience very positive employment conditions. Consequently, their services are generally in very high demand, with many starting out with six-figure annual incomes immediately after completion of their professional training.

I chose this topic because I a found it as a very interesting thing which I wanted to know more about. I have been CT-scanned when I had concussion after a car accident when I was seven. Also because my father has been under a CT-scanner and a lot of my friends.
