Description

What is DOSE?

DOSE is a dose management solution that automatically monitors, evaluates and optimizes the radiation dose that patients receive for multi-facility, multi-modality and multi-vendor imaging environments.

The solution provides direct insight into the daily dose management, the clinical image quality and the performance of your employees. Besides, it assures regulated reports that provide an efficient pro-active solution to the labour-intensive regulatory compliance monitoring.In this way, DOSE assists the users to maintain patient safety and quality in medical imaging.

Why DOSE?

DOSE is the most optimal solution for automated quality management in medical imaging. It gathers data from different sources within your facility and connects them to get an overall or detailed impression of the quality of your service. Qaelum are committed to the principles of ALARA (As Low As Reasonably Achievable) and constant quality improvement, we focus on automated patient radiation dose management, image quality assessment and lifetime learning of your staff.

As quality is of the utmost importance to us, Qaelum is a medical device manufacturer adhering to ISO-13485 and ISO-14971. DOSE has a number of certifications and quality labels including CE class IIb, CAMCAS level III (Canada) and FDA clearance for the US market.

Features

VirtualDose

VirtualDose enables you to estimate more accurately the effective dose and organ dose for a patient in a CT examination. A vast library of 25 anatomically correct phantoms is at your disposal: phantoms of several body sizes, different genders, pediatric phantoms and even different stages of pregnancy. Consequently, you can simulate the fetal dose in case of pregnancy more precise. VirtualDose is a very useful simulation tool to test 'what if' scenarios and to educate your staff.

Reject Analysis

For RX modalities, you can evaluate the rejected images at the device and give advice on how to optimize the training of your personnel.

Live dashboard

The concept of live dashboards enables immediate feedback regarding dose and quality. The technician has the possibility to justify the performed exam by adding comments. All these comments can be collected inside one report and can be used to personalize additional training per technician.

Patient Dose Passport

Because DOSE is integrated in the PACS, you can easily request the patient dose passport. It contains all registered dose information from this particular patient, including the type and number of studies they have had and the interval between these studies. By doing so, you can easily track the patient’s cumulative dose and assess if it is still below achievable level.

Workload

The moment evaluation graph allows you to simultaneously see the number of studies and the applied dose on a particular day and time. The statistical overview reveals differences in dose during the day versus night, morning versus afternoon and week versus weekend.

In addition, our software also provides a workload analysis graph, which monitors the (in)activity of different modalities. This tool can be used to optimize the use of your modality and the number of technicians per device.

Blind Scanning

Blind scanning should be avoided since the CT scan doesn’t know exactly how to behave or what dose to use. This problem is evaluated by DOSE since it checks and measures blind scanning.

Size Specific Dose Estimate (SSDE)

Considering all dose calculations in CT are estimated on phantoms, they are not representative for every patient; because unlike a phantom, not all patients are equal in size. Consequently, DOSE aims to resolve this problem by doing a segmentation on the scout image and recalculating the patient’s real size.

Peak Skin Dose

Peak Skin Dose is a module applied for interventional radiology devices and estimates the maximum skin dose that is delivered during an interventional procedure. The information is represented in a Peak Skin Dose map, which uses color coded pixels to indicate the amount of radiation delivered to a particular area of skin. In addition, tube angulation, table movement, fluoroscopy dose, etc. are also monitored. Consequently, Peak Skin Dose is a perfect tool to optimize interventional procedures.

Compliance Monitoring

DOSE allows you to continuously capture all radiation dose data to evaluate compliance. Our solution works with a ‘traffic light’-system, which informs you on Diagnostic Reference Levels (DRLs). Whenever the achievable or acceptable regulatory levels are surpassed, the study or series will be flagged orange or red respectively.

Integrated reporting & exporting

  • All data in the system can be exported to popular formats like MS Excel or PDF on study, modality or location level
  • Reporting modules, i.e. Leapfrog reporting: automatic export to the different MS Excel Leapfrog templates with automated study selection and with auto-selection of the appropriate date range
  • 600+ visualization and analysis components
  • Creation of mini-websites with analysis components of interest for easy collaboration

 The Joint Commission

DOSE helps achieve compliance with the Joint Commission requirements for CT and fluoroscopy. 

With DOSE you set up unique combinations and monitor progress intuitively for key factors like skin dose, air kerma-area product (KAP), air kerma at a reference point, … You can set notifications on individual parameters that exceed a pre-set threshold, but also on cumulative parameters within a specific time interval. Specifically, DOSE helps caregivers track patient’s cumulative radiation dose from multiple examinations. The system enables setting up a threshold and time period after the patient’s first examination, thus creating a standard for monitoring future dose based on your institution’s requirements and/or Joint Commission requirements. Reaching your compliance goals has never been easier.

Whenever the pre-set threshold is exceeded, a notification is generated. This can be accompanied by an email to the person in charge of these events in order to get notified quickly and perform the required actions.

Protocol management

Standardization and optimization of CT protocols is one of the corner stones of rigorous radiation protection plans! Due to the multitude of available protocols, the diversity over the different vendors and the complexity of these protocols, it is a very tedious and time-consuming process. The new Enterprise Protocol Management module of DOSE is a vendor-neutral solution to centrally manage and monitor the protocols of your CT scanners. This module allows professionals to perform the following tasks.

protocol management 1

Protocol Standardization

  • define all the master protocols of your protocol tree with an easy to use, intuitive user interface. Elements that can be defined are: the protocol structure, key scanner settings, contrast details, and a corresponding Radlex code
  • import existing protocol trees to speed up the configuration process

Protocol Harmonization

  • link the individual protocols of different scanners to the master protocols
  • identify differences in the implementation of master protocols on different scanners
  • use pre-defined workflows to initiate and follow-up tasks for changing settings on the CT scanner

Protocol Distribution

  • to ensure access to the latest version of the different protocols for all the stakeholders, the module allows for re-publishing the protocols in user-definable templates, with actual radiation dose information included
  • the public API of the module allows for a tight integration of the distributed, up-to-date protocols into the daily work environment of the technologists

protocol management 2

Protocol Monitoring

  • the module monitors modifications in the protocol tree of individual CT scanners. Additions, removals, or alterations of protocols are tracked. This helps to examine all of the changes and if they are permitted
  • depending on the local situation, DOSE can connect to your CT scanners and automatically retrieve and analyze the protocol files

Protocol Usage

  • in combination with DOSE, the overall usage of the scanner protocols is evaluated, and statistics are generated
  • pre-defined rules identify protocols that have not been used recently or that have been applied to a different population than indicated by the master protocol
  • changes of the protocol during an examination, trigger a notification to assist in the justification of inappropriate dose/performance
