X-ray LINK

X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white. Fat and other soft tissues absorb less and look gray. Air absorbs the least, so lungs look black.

The most familiar use of x-rays is checking for fractures (broken bones), but x-rays are also used in other ways. For example, chest x-rays can spot pneumonia. Mammograms use x-rays to look for breast cancer.

When you have an x-ray, you may wear a lead apron to protect certain parts of your body. The amount of radiation you get from an x-ray is small. For example, a chest x-ray gives out a radiation dose similar to the amount of radiation you're naturally exposed to from the environment over 10 days.

Computed tomography (CT): Combines traditional x-ray technology with computer processing to generate a series of cross-sectional images of the body that can later be combined to form a three-dimensional x-ray image. CT images are more detailed than plain radiographs and give doctors the ability to view structures within the body from many different angles. Learn more about CT here.

Fluoroscopy: Uses x-rays and a fluorescent screen to obtain real-time images of movement within the body or to view diagnostic processes, such as following the path of an injected or swallowed contrast agent. For example, fluoroscopy is used to view the movement of the beating heart, and, with the aid of radiographic contrast agents, to view blood flow to the heart muscle as well as through blood vessels and organs. This technology is also used with a radiographic contrast agent to guide an internally threaded catheter during cardiac angioplasty, which is a minimally invasive procedure for opening clogged arteries that supply blood to the heart.

Single-frame x-ray tomosynthesis (SFXT): Conventional x-ray radiography generates a single two-dimensional image, which is created by imaging a single plane at a single time point. X-ray tomosynthesis, on the other hand, uses multiple images, which are then reconstructed to generate more information, such as a three-dimensional image. Unlike CT imaging, where the source/detector physically travels at least 180 degrees around the patient, tomosynthesis uses a limited rotational angle and takes fewer images (requiring less radiation and less expense). Current tomosynthesis approaches, however, generate a static snapshot of the tissue of interest and do not allow for real-time imaging.

Imaging to guide lung biopsies: Lung cancer is the leading cause of cancer-related mortality in the United States, and analyzing lesions found in the lungs is a way to screen for the disease and to guide treatment. For a biopsy, one method to obtain lung tissue is through a bronchoscopy, where a thin tube is passed through the nose or mouth and guided into the lungs. However, obtaining tissues of interest remains difficult, as locating and visualizing such lesions is challenging. To overcome these limitations, researchers have developed a new, cost-effective chest x-ray tomosynthesis system that can generate high-resolution, real-time images of the lungs, which would allow for improved visualization during a transbrochial biopsy. In addition to being less expensive and easier to use than standard CT-based approaches, this x-ray technique is stationary and does not require any physical motion of the x-ray source or detector. Further, this method uses low doses of radiation, which would be beneficial for patients who require multiple biopsies. This x-ray system is currently being optimized for pre-clinical large animal evaluation.

Manufacturers of diagnostic x-ray systems intended for human use are required to file reports of assembly upon installation of a certifiable system or component(s). The report of assembly (FDA Form 2579) represents the assemblers certification that the system or component(s) are of the type called for by the Standard (i.e., certified), have been assembled according to the instructions provided by the manufacturer, and meets the requirements of the applicable Federal standards contained in 21 CFR 1020.30 through 1020.33. Reports must be submitted to the purchaser and, where applicable, to the State agency responsible for radiation protection within 15 days following completion of the assembly. Contact Information for State agencies is available on the website of the Conference of Radiation Control Program Directors (CRCPD), the organization of state radiation regulators. (If the pop-up information block includes "State Medical Contacts," select it and then select the "Form 2579" tab.)

Medical radiation machines make up the largest man-made source of exposure to the public. In 1958, the state Board of Health began a program to inspect radiation machines. Today over 20,000 facilities, including hospitals, doctors' offices, universities, and corporations, have registered more than 62,000 x-ray machines with the department.

The radiation machine program works to reduce exposure to workers and the public from machines that emit radiation for medical, scientific, educational, and industrial purposes. The program accomplishes this by:

The Maine Radiation Control Program - X-ray section is staffed by Bob Stilwell and Dan Quesada. The x-ray section registers approximately 1060 x-ray facilities . There is an annual registration fee per x-ray machine and a requirement for periodic inspections. These inspections are performed by third party Qualified Experts who are approved by the agency.

Dual-energy x-ray absorptiometry (DEXA) has sustained a niche for measuring bone mineral density since its approval by the Food and Drug Administration (FDA) for clinical use in 1988. The Bone Mass Measurements act in 1998 solidified its validity in light of other diagnostic modalities such as chemical analysis, direct dissection and ashing, quantitative ultrasonography, and later on against CT/MRI images. DEXA is comparatively inexpensive with notably shorter scan times and radiation exposure compared to other imaging options, and there is a long-standing consensus regarding guidelines for interpreting DEXA images. This activity reviews the indications, contraindications of DEXA and highlights the role of the interprofessional team in the management of patients with osteoporosis.

The COVID-19 peacetime emergency ends on July 1, 2021. All registrants affected by equipment performance modification of existing COVID-19 waiver or modification under Minnesota Session Laws - 2020, Regular Session, chapter 74, article 1, section 13, must return to normal statute and rule compliance on July 30, 2021. Registrants are strongly encouraged to begin the necessary planning for this transition as soon as possible and should contact x-ray unit at health.xray@state.mn.us with questions.

The Minnesota Department of Health (MDH) is issuing this Information Notice (IN) to inform correctional or detention facilities to the recent law changes to Minnesota Statute, 144.121 involving the use of security screening x-ray equipment for human use.

The 2019 Legislature authorized the use of security screening x-ray equipment to image and identify contraband items concealed within or on all sides of a human body. A facility must have a granted variance to Minnesota Rules, Chapter 4732 and meet the requirements before first use of the security screening x-ray equipment.

The length of time needed to do each x-ray depends on the type of x-ray that was ordered for your child. A typical x-ray takes about 10 minutes for positioning, while the actual x-ray exposure takes less than a second.

You likely have had x-rays before. X-rays, formally referred to as radiographs, are common imaging procedures ordered by healthcare providers and dentists. X-ray machines pass x-ray beams (a form of ionizing radiation) through a part of the body to produce images of the tissue, organs, bones, or teeth inside. These images allow healthcare providers and dentists to see if there are problems, like a broken bone or a cavity.

Healthcare providers and dentists both use x-rays for your care. A healthcare provider may recommend x-rays to look for bone fractures, some types of tumors, injuries or abnormal masses, and signs of pneumonia in the lungs.

Your healthcare provider or dentist should recommend an x-ray when they believe that the benefits to your health outweigh this small risk. Talk to your healthcare provider or dentist if you have concerns and to decide when x-rays are the best choice for you.

Medical and dental x-rays use very small amounts of radiation and only expose the smallest area of the body needed to get the image to check for a health concern. Your risk of any long-term effects of ionizing radiation from x-rays depends on the part of the body being x-rayed (some organs or tissues are more sensitive than others) and the amount of radiation exposure, which may include the total number of medical procedures using radiation, over time.

As in many areas of medicine, there are risks associated with the use of x-ray imaging, which uses ionizing radiation to create images of the body. Because the amount of radiation used in a normal x-ray procedure is small, there is a small risk for the patient. However, it is still important for patients to understand what to do if an x-ray procedure is suggested. 2351a5e196
