Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. It is referred to as ‘endoradiology’ because it records radiation emitting from within the body rather than radiation that is generated by an external source, such as an x-ray. Diagnostic nuclear medicine scans are different from radiologic scans because they show the physiological function of the system as opposed to traditional anatomical imaging such as a CT or MRI. In nuclear medicine imaging, radiopharmaceuticals are taken internally, intravenously or orally. External detectors capture and form images from the emitted radiation. Single photon emission computed tomography (SPECT) and positron emission topography (PET) scans are the two most common imaging modalities in nuclear medicine.
There are some practical concerns in nuclear imaging. Because the risks of low-level radiation are not completely understood, a cautious approach has been universally adopted. All human radiation exposures should be kept at As Low as Reasonably Practicable (ALARP).
According to this principle, before a patient is exposed to radiation through a nuclear medicine examination, the benefits of the examination must be identified. The particular circumstances of the patient must be considered. For example, if the patient cannot tolerate a sufficient amount of the procedure to achieve a diagnosis, it would be inappropriate to proceed with injecting the patient with the radioactive tracer. If the benefits from the procedure justify its use, the radiation exposure to the patient should be kept as low as is reasonably practicable. The images produced in nuclear medicine should never be better than required for a confident diagnosis. Giving larger radiation doses can reduce the noise in an image and make it more photographically appealing, but if the diagnostic questions can be answered without that level of detail, it is inappropriate to increase the radiation dosage.
The radiation dose from nuclear medicine imaging varies depending upon the type of study. An effective radiation dose can be lower than, comparable to, or far exceed the general day-to-day environmental background radiation dose. It can also be less than, in the same range, or higher than the radiation dose from a CT scan on the abdomen area or the pelvis. Some nuclear medicine procedures require that patients prepare before the study to obtain the most accurate results. This preparation may include dietary restrictions or the withholding of certain medications.

The goal of having a prototype is to test a product idea before spending time and money on the final product. A prototype has four basic qualities: representation, precision, interactivity and evolution. Medi-Ray produces prototypes based on a customer’s design with refinements by Medi-Ray’s design personnel. For additional information, call 877-898-3003 or 914-979-2740 or email email@example.com.
Many of us have had X-Rays taken in hospitals, emergency clinics or doctors’ and dentists’ offices. Radiology, which is the science of X-Rays and high-energy radiation, is extremely important in the diagnosis and treatment of many diseases and health conditions. However, there continues to be some common myths about the dangers and risks as it relates to radiation that can be dispelled with the correct information.
Myth: Any exposure to radiation is not safe and will cause side effects.
Reality: People are continuously exposed to radiation everyday while eating food and breathing air. A study by the UN Scientific Committee showed that the risk associated with low-dose radiation is very small. During X-Rays, MRIs and other scans, the small amount of radiation an individual is exposed to will not cause side effects.
Myth: Pregnant women should not have radiology scans.
Reality: There is no evidentiary proof that a fetus is physically harmed from an ultrasound. A 3D scanner does not use stronger sound waves or produce more heat than a 2D scan, so it is equally as safe for infants.
Myth: Radiation treatment causes cancer.
Reality: The chances of getting cancer from radiation treatment is extremely small and depends on the person’s age at the time of treatment, the area of the body that is being treated and the dosage.

The two basic types of radiation are ionizing radiation and non-ionizing radiation. Non-ionizing radiation refers to a series of oscillating energy waves composed of electric and magnetic fields that travel at the speed of light. Examples are the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF) and extremely low frequency (ELF). Non-ionizing radiation is found in a wide range of occupational settings and may pose a health risk to exposed workers if not properly controlled. The six basic sources of this type of radiation are:
Extremely Low Frequency Radiation (ELF): This is produced by power lines, electrical wiring and electrical equipment. Intense exposure sources are induction furnaces and high-voltage power lines.
Radiofrequency and Microwave Radiation: Microwave radiation (MW) is absorbed near the skin and radiofrequency radiation (RF) can be absorbed throughout the body. At high intensities, both can damage tissues in the body through heating. RF and MW radiation sources are radio emitters and cell phones.
Infrared Radiation: Your eyes and skin absorb infrared radiation (IR) as heat. Sources of IR radiation include furnaces, heat lamps and IR lasers.
Visible Light Radiation: Different frequencies of the electromagnetic (EM) spectrum are seen as different colors. Having sufficient lighting is important but excessive visible radiation can damage the eyes and skin.
Ultraviolet Radiation: Ultraviolet Radiation (UV) is very hazardous because there are no immediate symptoms of excessive exposure. Some sources of UV radiation are the sun, black lights, welding arcs and UV lasers.
Laser Hazards: Lasers typically emit optical (UV, visible light, IR) radiations and can be hazardous to the skin and eyes. Some common lasers are CO2, IR laser, helium-neon, neodymium, YAG and ruby visible lasers, and the Nitrogen UV laser.
Ionizing radiation sources can be found at healthcare facilities, nuclear reactors, nuclear weapon production facilities and research institutions. These radiation sources can pose a considerable health risk to workers if not properly controlled. This is a type of energy released by atoms in the form of electromagnetic waves. People are exposed to natural sources of ionizing radiation in the soil, water, vegetation, x-rays, medical devices and other beneficial applications. Acute health effects such as skin burns or acute radiation syndrome can occur when specific radiation levels are exceeded. Long term effects of ionizing radiation can increase the risk of cancer.

If you have a new idea and are involved in the design process, one of the most important steps is the creation of a prototype. A prototype can be almost anything, from a series of drawings to a perfect replica. The most basic definition of a prototype is “A simulation or sample version of a final product, which is used for testing prior to launch.” The goal of having a prototype is to test product ideas before spending time and money on the final product.
Prototyping is essential in the creation of new products. It can resolve usability issues and reveal areas that need improving or discarding. When a sample of your product idea is being used by real consumers, you get an idea of how they want to use the product. Consistent adjustments during the prototyping process are being made all the time to make sure that all the facets or components of the item are working the way you intended. Prototypes have four basic qualities:
Representation: This refers to the actual form of the prototype, i.e., paper and mobile, or HTML and desktop.
Precision: The prototype’s fidelity, i.e., its level of detail, polish and realism.
Interactivity: This refers to how functional it is to the user, e.g., fully or partially functional or available for viewing only.
Evolution: This refers to the ‘lifecycle’ of a prototype. Some prototypes are built quickly, tested and discarded, and eventually replaced by an improved version, called ‘rapid prototyping.’ Others are built, improved upon and ultimately become the final product.
A common misconception is that prototyping only needs to be done a couple of times toward the end of a design process. It is far more beneficial to test early on and often and it is a good idea to prototype every phase of your design, from the first and most basic iteration. Prototypes don’t just look like the final version of your design. They are a version of the design that can be used for testing.
Medi-Ray produces prototypes based on a customer’s design with refinements by Medi-Ray’s design personnel. Second and third stage prototypes take designs all the way to the final dimensions for DOT testing, customer production requirements and marketing personnel approval.

Medi-Ray counterweights are necessary for many types of equipment. They may be as simple as steel plates or designed with complex geometrics. When you are designing a product that will need counterweights, there are many factors to consider. These factors include how much you will need, whether the counterweights will be freestanding or inside a compartment, how much space you have to work with, etc. Counterweights can be made of steel or lead, depending upon the application. If they are manufactured using lead, the lead can be coated with powder or painted for safe handling. Some applications for counterweights include medical equipment, aerospace, bridges, forklifts, cranes, elevator weights and sonar weights. Below are only a few examples of other applications for counterweights:
The famous leaning tower of Pisa in Italy uses counterweights to ensure that the building does not continue to lean and eventually fall.
On a construction site, elevators use counterweights to balance the load of the elevator car.
A crane is a mechanism that balances the load it is carrying with a lead counterweight by utilizing a horizontal boom across the top of the tower.
A bascule bridge is moveable due to a counterweight that continuously balances the span when it swings upward to allow for boat traffic.
Crankshafts in piston engines use counterweights to reduce vibrations.
Desk lamps use counterweights to keep the lamp in the appropriate position.
A metronome has an adjustable spring mechanism that allows the speed to increase or decrease by using counterweights.
Amusement park rides use counterweights to ensure the safety of their riders.
