(1) "ARMRIT" means the American Registry of Magnetic Resonance Imaging Technologists.
(2) "ARRT" means the American Registry of Radiologic Technologists.
(3) "Computed tomography" or "CT" means technology that uses computer-processed X-rays to produce tomographic images or virtual slices of specific areas of the patient's body or scanned object.
(4) "Department" means the department of health.
(5) "Direct supervision" means the appropriate licensed practitioner is on the premises and is quickly and easily available.
(6) "General supervision" for a radiologist assistant means the procedure is furnished under the supervising radiologist's overall direction and control. The supervising radiologist is on-call or be available for consultation.
(7) "Indirect supervision" means the supervising physician is on site no less than half-time.
(8) "Licensed practitioner" means a licensed health care practitioner performing the services within the person's authorized scope of practice.
(9) "NMTCB" means the nuclear medicine technology certification board.
(10) "Nonionizing radiation" includes radiation such as radiofrequency or microwaves, visible, infrared, or ultraviolet light or ultrasound.
(11) "Peripherally inserted central catheter" or "PICC line" means a form of intravenous access for administration of substances.
(12) "Personal supervision" means the supervising physician must be in the room during the performance of the procedure.
(13) "Radiologic technologist" means a person certified under chapter 18.84 RCW, other than a licensed practitioner, who practices radiologic technology as a:
(a) Diagnostic radiologic technologist, who is a person who actually handles X-ray equipment in the process of applying radiation on a human being for diagnostic purposes at the direction of a licensed practitioner. This includes parenteral procedures related to radiologic technology when performed under the direct supervision of a physician licensed under chapter 18.71 or 18.57 RCW;
(b) Therapeutic radiologic technologist, who is a person who uses radiation-generating equipment for therapeutic purposes on human subjects at the direction of a licensed practitioner. This includes parenteral procedures related to radiologic technology when performed under the direct supervision of a physician licensed under chapter 18.71 or 18.57 RCW;
(c) Magnetic resonance imaging technologist, who is a person who uses a nonionizing radiation process on a human being by which certain nuclei, when placed in a magnetic field, absorb and release energy in the form of radio waves that are analyzed by a computer, thereby producing an image of human anatomy and physiological information at the direction of a licensed practitioner. This includes parenteral procedures related to radiologic technology when performed under the direct supervision of a physician licensed under chapter 18.71 or 18.57 RCW;
(d) Nuclear medicine technologist, who is a person who prepares radiopharmaceuticals and administers them to human beings for diagnostic and therapeutic purposes, and who performs in vivo and in vitro detection and measurement of radioactivity for medical purposes at the direction of a licensed practitioner;
(e) Radiologist assistant, who is an advanced-level certified diagnostic radiologic technologist who assists radiologists by performing advanced diagnostic imaging procedures as determined by rule under levels of supervision defined by the secretary. This includes, but is not limited to, enteral and parenteral procedures when performed under the direction of the supervising radiologist, and that these procedures may include injecting diagnostic agents to sites other than intravenous, performing diagnostic aspirations and localizations, and assisting radiologists with other invasive procedures; or
(f) Cardiovascular invasive specialist, who is a person who assists in cardiac or vascular catheterization procedures under the personal supervision of a physician licensed under chapter 18.71 or 18.57 RCW. This includes parenteral procedures related to cardiac or vascular catheterization including, but not limited to, parenteral procedures involving arteries and veins.
(14) "Radiologic technology" means the use of ionizing or nonionizing radiation upon a human being for diagnostic or therapeutic purposes.
(15) "Radiologist" means a licensed physician licensed under chapter 18.71 or 18.57 RCW and certified by the American Board of Radiology or the American Osteopathic Board of Radiology.
(16) "Registered X-ray technician" means a person who is registered with the department, and who applies ionizing radiation at the direction of a licensed practitioner.
(17) "Secretary" means the secretary of the department of health.
(18) "Venipuncture" means a procedure to puncture a vein to withdraw blood or to start intravenous infusion related to radiologic technology but does not include the insertion of PICC lines.
