1. "Diagnostic computed tomography" means the use of computed
tomography to create cross-sectional images of the human body to be used for
diagnosis.
2. "Attenuation correction" means the use of X-rays from a CT
scan to construct an attenuation map of density differences throughout the body

and clinical instruction which meets the training standards set by the
department.
"Ionizing radiation producing machine" or
"radiation machine" means an assemblage of components for the
controlled production of X-rays. An ionizing radiation producing machine
includes minimally an X-ray high-voltage generator, an X-ray control, a tube
housing assembly, a beam-limiting device, and the necessary supporting
structures. Additional components which function with the system are considered
integral parts of the system.
"NMTCB" means Nuclear Medicine Technology
Certification Board.
"Nuclear medicine diagnostic computed tomography
endorsement" means a qualification that allows a nuclear medicine
technologist to perform diagnostic computed tomography of the human body as
ordered by an individual authorized by Iowa law to order radiography.
"Nuclear medicine procedure" means any
procedure utilizing radiopharmaceuticals for diagnosis or treatment of disease
in human beings and any duties performed by the technologist during sealed
source procedures, and includes, but is not limited to:
1. Administration of any radiopharmaceutical to human beings
for diagnostic purposes.
2. Administration of radioactive material to human beings for
therapeutic purposes.
3. Use of radioactive material for diagnostic purposes
involving transmission or excitation.
4. Quality control and quality assurance.
"Nuclear medicine technologist" means an
individual who performs nuclear medicine procedures while under the supervision
of an authorized user. The classifications are as follows:
1. "General nuclear medicine technologist" performs any nuclear
medicine procedures and may perform computed tomography for attenuation
correction during PET/CT or SPECT/CT only.
2. "Limited nuclear medicine technologist" performs nuclear
medicine procedures only as approved by the department at the time the initial
permit was issued.
"Permit" means the document issued to an
individual by the department when the individual has met the requirements of
this chapter. This document authorizes the individual to perform the duties
allowed for the classification of permit issued.
"PET/CT" means an imaging modality that uses
positron emission tomography and computed tomography in one device to combine
the structural anatomic information with functional data collected during the
examination.
"Radiation therapist" means an individual who
performs radiation therapy under the supervision of a radiation oncologist
licensed in Iowa.
"Radiation therapy" means the science and art
of performing simulation radiography or applying ionizing radiation emitted
from X-ray machines, particle accelerators, or radioactive materials in the
form of sealed sources to human beings for therapeutic purposes.
"Radiography" means a technique for generating
and recording an X-ray pattern for the purpose of providing the user with an
image(s) during or after termination of the exposure.
"Radiologic technologist" means an individual,
excluding X-ray equipment operators, who performs radiography of the human body
as ordered by an individual authorized by Iowa law to order radiography. The
classifications are as follows:
1. "General radiologic technologist" performs radiography and
computed tomography of any part of the human body.
2. "Limited radiologic technologist" performs radiography for
the chest, spine, extremities, shoulder or pediatrics, excluding computed
tomography and fluoroscopy.
3. "Limited in-hospital radiologic technologist" performs
radiography of any part of the human body as approved by the department at the
time the initial permit was issued.
"Radiologist assistant" means an
advanced-level radiologic technologist who has completed the necessary
requirements in order to perform procedures as outlined in ARRT guidance while
under supervision of a radiologist.
"SPECT/CT" means an imaging modality that uses
single-photon emission computed tomography and computed tomography in one
device to combine the structural anatomic information with functional data
collected during the examination.
"Student" means an individual enrolled in and
participating in formal education.
"Therapeutic" means a medical treatment using
radiation for therapy purposes.
"X-ray equipment operator" means an individual
performing radiography of the human body using dedicated equipment as ordered
by an individual authorized by Iowa law to order radiography. These individuals
do not qualify for a permit in any other classification. The classifications
are as follows:
