The National Electrical
Manufacturers Association’s Medical Imaging & Technology Alliance (MITA) has
published XR 29 Standard Attributes on
Computed Tomography (CT) Equipment Related to Dose Optimization and Management.
XR 29, also known as MITA Smart Dose, includes four key features of CT
equipment that enable optimization or management of radiation dose delivery
while also providing high quality medical images.
“MITA continues its dose
reduction efforts with the approval of MITA Smart Dose, a standard that offers
healthcare providers an additional tool to optimize and manage dose in CT
scanning,” said Gail Rodriguez, executive director of MITA. “We look forward to
working with our industry partners to promote the adoption of MITA Smart Dose,
and increase patient access to these technologies.”
Several attributes of CT
equipment help physicians and technologists optimize and manage dose. The MITA
Smart Dose standard bundles four of these important features to ensure that
compliant equipment produces high-quality diagnostic images while supporting
patient safety. They are:
(Digital Imaging and Communications in Medicine) Radiation Dose Structured
Report, which enables recording of post-exam dose information in a
standardized electronic format. This information can be included in the
patient record, promoting the establishment of diagnostic reference
levels, as well as facility dose management and quality assurance.
Dose Check, which incorporates two features—dose notifications and dose
alerts—that warn operators and physicians when dose exceeds established
exposure controls (AEC), which automatically adjust the amount of
radiation within prescribed bounds as needed to achieve the desired image
quality. Studies of AEC procedures have demonstrated dose reductions when
and adult reference protocols, a set of pre-loaded parameters on a CT
system that can be selected by the operator to complete a particular
clinical task, such as capturing an image of the abdomen.
According to the Food and
Drug Administration (FDA), it values the collaboration and work done by
industry and the medical imaging community to promote patient safety.
“We also encourage radiology
facilities to use equipment safety features and to adopt imaging best practices,”
said Mary Pastel, PhD, Deputy Director for Radiological Health, Office of In
Vitro Diagnostics and Radiological Health, FDA Center for Devices and
XR 29 is the fourth
dose-related standard to be released by MITA since 2010. Collectively, the
series promotes adoption and use of advances in dose management and mitigation:
25 Computed Tomography Dose Check
incorporates dose notifications and alerts.
26 Access Controls for Computed
Tomography: Identification, Interlocks, and Logs requires software
features ensuring that only an authorized operator can alter the controls
of CT equipment.
27 X-Ray Equipment for Interventional Procedures User Quality Control Mode helps imaging facilities conduct quality testing and monitoring of
X-ray equipment used for interventional procedures.
