Fluoroscopic imaging assembly means a subsystem in which X-ray photons produce a visual image. It includes the image receptor(s) such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and diagnostic source assembly.
Fluoroscopy means a technique for generating x-ray images and presenting them simultaneously and continuously as visible images. This term has the same meaning as the term "radioscopy" in the standards of the International Electrotechnical Commission.
Electrostatic spray means a method of applying a spray coating in which opposite electric charges are applied to the substrate and the coating. The coating is attracted to the substrate by the electrostatic potential between them.
Diagnostic mammography means a method of screening that
Electrostatic application means the application to a substrate of charged atomized paint droplets that are deposited by electrostatic attraction.
Cabinet radiography means industrial radiography conducted in an enclosure or cabinet shielded so that radiation levels at every location on the exterior meet the limitations specified in 641—40.26(136C).
Radiation therapy simulation system means a radiographic or fluoroscopic x-ray system intended for localizing the volume to be exposed during radiation therapy and confirming the position and size of the therapeutic irradiation field.
Tissue means a portion of the human body other than an organ or an eye. The term does not include blood unless the blood is donated for the purpose of research or education.
Disposable respirator means a respirator for which maintenance is not intended and that is designed to be discarded after excessive breathing resistance, sorbent exhaustion, physical damage, or end-of-service-life renders it unsuitable for use. Examples of this type of respirator are a disposable half-mask respirator or a disposable escape-only self-contained breathing apparatus (SCBA).
Source-image receptor distance means the distance from the source to the center of the input surface of the image receptor.
Diagnostic source assembly means the tube housing assembly with a beam-limiting device attached.
Sensor means any measurement device that is not part of the vehicle itself but installed to determine parameters other than the concentration of gaseous and particle pollutants and the exhaust mass flow.
COVID-19 symptoms means fever of 100.4 degrees Fahrenheit or higher, chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, or diarrhea, unless a licensed health care professional determines the person’s symptoms were caused by a known condition other than COVID-19.
Cell means a single encased electrochemical unit containing one positive and one negative electrode which exhibits a voltage differential across its two terminals.
Web spray adhesive means any aerosol adhesive that is not a mist spray or special purpose spray adhesive.
Non-surgically implanted prostheses means a replacement body part not surgically implanted.
coronavirus means severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2);
Step therapy protocol means a protocol or program that establishes the specific
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
Instantaneous flow measurement means the flow measured during the minimum time required for the flow-measuring device or method to produce a result in that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab samples required for the same sampling period so that together the samples and flow are representative of the discharge during that sampling period.
thalassemia means a group of inherited disorders characterised by reduced or absent amounts of haemoglobin.
Biodegradable means degradable through a process by which fungi or bacteria secrete enzymes to convert a complex molecular structure to simple gasses and organic compounds.
Biological agent shall mean any pathogenic (disease producing) micro-organism(s) and/or biologically produced toxin(s) (including genetically modified organisms and chemically synthesized toxins) which cause illness and/or death in humans, animals or plants.
Radiography means a technique for generating and recording an x-ray pattern for the purpose of providing the user with an image(s) after termination of the exposure.
External beam radiation therapy means therapeutic irradiation in which the source of radiation is at a distance from the body.
Optical means services related to the provision of glasses, contact lenses, tests and treatments carried out by a registered optometrist or ophthalmologist.
