4.1.3.2. Imaging technique
Protocols and procedures for all imaging examinations should be
documented and regularly updated, and they should be readily accessible to
imaging staff at all times. All examination protocols should be optimized for
image quality and dose, with input from the relevant imaging team members: the
radiological medical practitioner, radiographer and medical physicist. The
recommended techniques and parameters should be based on the principle of
exposing the patient to the least radiation dose necessary to achieve the
appropriate diagnostic information (see Section 5). In special populations, such as
paediatrics, specific documentation relevant to these populations should be in
place.
Recommended radiographic technique factors should be used for
preprogramming of equipment, or they should be readily available for use by the
radiographer.
Recommended practice for secure storage of image data should be
observed, including backup of electronic data and image data management
through the Picture Archiving and Communication System (PACS).
It should be ensured that members of staff are aware of current protocols
and procedures, and immediately notified when changes are made.
Protocols and procedures should be in place for studies such as:
—Plain radiography;
—Fluoroscopy;
—Mammography;
—Computed tomography;
—Ultrasonography;
—Magnetic resonance imaging;
—PET/CT;
—Image guided procedures;
—Dental radiography.
There should be a documented process to indicate the circumstances in
which radiographers or radiological medical practitioners/physicians who are in
training should seek further guidance from the supervising radiographer or
radiological medical practitioner/physician, respectively, such as:
(a)
(b)
Unexpected imaging findings;
Difficulties in obtaining the image required because of patient or equipment
problems.
