Frequently Asked Questions (FAQs):


What are the four attributes of the NEMA XR-29 standard?

Z-DOSE29 complies with the 4 attributes of the NEMA XR-29 standard:


  • DICOM Radiation Dose Structured Report: 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.
  • CT Dose Check: Incorporates two features—dose notifications and dose alerts—that warn operators and physicians when dose exceeds established thresholds
  • Automatic Exposure Control (AEC)*: 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 used properly.
  • Pediatric 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.

* AEC/Dose modulation feature must be installed on the scanner to qualify for our upgrade


What is Z-DOSE29?

Z-DOSE29 is an intuitive dose monitoring device developed by Zetta Medical Technologies to make your CT scanner compliant with the XR-29 standard, CMS and Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) dose monitoring requirements.  It is a XR-29 solution and is considered non-invasive, meaning no changes to the CT scanner hardware of software are required.  It connects to your network (just like a PACs system) and it interacts with the CT scanner through secure, precise and fast networking techniques.


Is Z-DOSE29 a FDA 510(k) cleared device?

Yes, Z-DOSE29 is FDA 510(k) cleared.  Z-DOE29 is non-invasive to the scanner hardware or software.  It connects to the facility network via a network cable and it communicates with the scanner via the facility network utilizing proprietary networking algorithms. 



How Does Z-DOSE29 Work?

The setup process takes a couple of hours and it includes the time for physical installation needed to connect Z-DOSE29 to your network.  Through secure networking protocols and proprietary connectivity algorithm Z-DOSE29 interacts with your CT scanner to determine the CTDi and DLP values for each series and notifies the CT technologist of any values exceeding the predefined threshold.  It also records these values in a database for the department manager to view dose reports and charts.  Dose Check notifications appear on the display screen of the CT scanner in front of the technologist.  The technologist will have the opportunity to modify the parameters to lower the dose values.  Alternativey, the operator can enter a reason for exceeding a dose threshold for these situations where it is necessary to do so.

For each study, and as Z-DOSE29 adds up the CTDI values for every series (and automatically records it in the database), it tracks the sum of all values to ALERT the technologist if the total sum for one study reaches 1000mGy.  This alert condition is a safety feature to ensure patient's safety and protects the healthcare provider as well as the operator. In this case, scanning can not begin until a password is entered to unlock the generation of X-Ray.  Simultaneously, an electronic alert notification will also be sent to the facility director of this high dose condition.

Z-DOSE29 collects the data needed to generate a comprehensive Radiation Structured Dose Report and prepares it for transfer to the ACR Dose Index Registry (DIR).  A user-friendly database of dose information is also provided to allow supervisors and department directors to access the data and generate a multitude of reports ad charts to measure performance and operations.  These reports are detailed and can be shared with CMS, JCAHO and ACR professionals to demonstrate dose management and tracking capabilities. Access to this Dose Database is secure with unique username(s) and password(s).

For healthcare providers with multiple facilities and different locations we offer Z-DOSE29 PLUS to give you a centralized server to view all Dose data in one easy application with secure connectivity and secure multiple users log-ins.

Training of your technologists for Z-DOSE29 and Z-DOSE29 PLUS is part of what we do.  We offer on-site training for your team and back it with telephone and remote support to make sure you are always up and scanning.


What are the requirments for dispalying Dose Notifications and Alerts?

Dose Notifications/Alerts must be dispayed on the CT (or PET/CT) Operator's Console and not on any other alternative/external monitors.  This is a basic requirment for any solution to comply with the XR-29 standard.  Z-DOSE29 displays the dose notifications/alerts on the operator's console; without the need to utilize any external (and unnecessary monitors). Here is an excerpt from NEMA XR-25 Computed Tomography Dose Check, section 2.1.2: 

“2.1.2 Checking Prior to SCANNING The NOTIFICATION VALUE(S) for the current PROTOCOL ELEMENT(S) shall be visible to the operator prior to confirmation of the PROTOCOL ELEMENT GROUP. When a PROTOCOL ELEMENT GROUP is confirmed, the system shall display a notification (see 2.1.4) on the operator’s console if the estimated CTDIvol or DLP exceeds the corresponding NOTIFICATION VALUE(S). The notification shall be displayed prior to the start of the SCAN, and shall never interrupt the SCAN.”


Also the MITA letter "Is-Your-CT-Smart-Dose-Compliant-Whitepaper.pdf" issued in May 2015 states clearly that the Dose Notifications MUST appear on the CT Operator Console for the CT to be compliant.

Excerpt from Page 2:


The CT Dose Check ......

.....  dose related notification and alert messages must appear on the operating console of the CT scanner prior to starting a scan in order for the system to be compliant...."

And Page 3:

"d. Dose Check: Do alerts and notifications appear on the operating console of the CT scanner prior to starting a scan? "


What is the purpose of the password in case of a Dose Alert situation?

Both NEMA XR-29 (which also includes XR-25) and Z-DOSE29, require the operator to input a secure password (prior proceeding to scan) if the total CTDI value for the study will exceed the total  threshold value (as determined by the healthcare provider). Unless the correct password is entered, the scanner's operator will not be able to start scanning. This feature is a requirement of the XR-29 standard. Please see the excerpt from the NEMA XR-25 Computed Tomography Dose Check section 2.2.2 below:

“2.2.2 Checking Prior to SCANNING


To proceed with SCANNING when an ALERT VALUE has been exceeded, the system shall require the operator to enter his/her name and reconfirm the chosen PROTOCOL ELEMENTS before proceeding to the SCAN. The system shall also provide password-protection capability that prevents execution of the SCAN unless the correct password is entered.
