Dose Registry Support Services Success Stories

Here are recent examples of the successes two of our sites reported to their radiation safety committees. This first example is a chart showing one facility’s average monthly Total DLP for its Chest Angio studies from early 2016 through Q1 2018.  Overall, this site reduced its average Total DLP for its Chest Angio studies by… Read More

TJC Dose Monitoring Requirements: XR-29 Dose Notifications Don’t Meet Them

When the facility I was working with was exploring using their scanners’ XR-29 Notifications to meet PI 02.01.01.A6 Dose Incident Identification requirements we reviewed the technical elements underpinning XR-29’s Dose Check feature.  After reading them we grew very concerned that XR-29’s dose notifications would not meet TJC’s requirement.  The facility submitted a question to TJC… Read More

Dose Index Registry Exam Name Mapping Made Easy – On Sale

Reviewing existing exam name RPID mapping assignments is one of the most important Dose Index Registry® (DIR) maintenance tasks facilities should routinely perform.

During the presentation  I gave an overview of the DIR and shared what we’ve learned from having participated in it for four years, including specific… Read More

CTDIvol vs DLP – a simple explanation

What do they represent? CTDIvol is based on measurements obtained when scanning either a 16cm or 32 cm phantom.   Essentially, it represents scanner output.  DLP is derived from CTDIvol, but incorporates a scan length component.  Both function as reasonable proxies for absorbed dose but do not represent the actual patient dose.  In other words, if… Read More

End of Quarter: Time to Perform Your DIR Data Quality Checks

With the end of the quarter approaching the ACR’s NRDR sent a reminder to all participants to perform several quality checks so your report will be as accurate as possible.  These checks include making sure: The total volume of exams recorded in the DIR for your facility is reasonably close to the volume of studies… Read More

Dose Reduction Case Study – Is Your CT Scanner Table Increasing Patient Dose?

During the 2017 Landauer Clinical Dose Optimization Symposium one of the session speakers, Douglas Pfeiffer, a medical physicist with Blackthorn Medical Physics, reported he had found the table-head rest extension connection mechanism increased CTDIvol and DLP when the body part being imaged was positioned over the connection mechanism.  Following the symposium, we worked with a… Read More

DoseID helps facilities identify duplicate and superfluous scanner protocols

One of the more interesting and unique benefits Dose Registry Support Services’ DoseID Program has for facilities is its ability to shed light on duplicate and superfluous protocols in use at their facilities.  The table to the right shows how one facility had 7 different protocols being used on a single scanner during a recent 3 month… Read More
