Ocean™ software for X-ray QA

Ocean™, the market-leading software for X-ray QA, addresses customer needs all the way from easy-to-use Ocean Quick Check for daily checks, to advanced QA with workflow, automation, and traceability in Ocean Professional.

The Ocean software suite is central to RTI's X-ray solutions and is compliant with all our product lines.

Ocean™: Market-leading software suite for X-ray QA

The importance of dedicated software applications to conduct professional QA is growing. Excel is flexible but simply not enough to meet the increasing demands for traceability, compliance, and efficiency.

Independently, if you want a swift, easy-to-use application for routine controls, or a customized application with workflow, automatic tests, and traceability, the Ocean™ software suite provides you with both options.

Ocean can run on both computers and tablets, thus you can choose the display you want. If you still want to make very simple checks only with no need for data management, we recommend our Cobia platform with a built-in display.

Quick Check: Swift, daily QA

Ocean Quick Check lets you start measuring within seconds. The application detects what instrument and probes you have connected to assist you in the best way possible – just “Plug n Play”. The interface adapts and all the measured parameters are displayed on one screen. The results and waveforms can be retained in the database for later review and compiled in a report.

Ocean Professional: Advanced QA for superior efficiency and compliance

Ocean Professional is a very powerful application for customized and advanced analysis of X-ray QA. To become really efficient, but also to assure compliance and traceability, you simply implement your QA process in Ocean.

Using the powerful Ocean “templates” feature, you can build your QA exactly the way you want it, e.g., predefined workflows, automation of steps, graphs, trend analysis, etc., all with full traceability. The report can be customized with your own logo and own layout. Comments and pictures can be added. The reports will look uniform and professional.

Ocean Central

Ocean Central is an on-premise (or cloud-based) add-on solution for Ocean Professional. Ocean Central helps you to assure all team members use the right QA protocol and store measurements centrally. You can easily overview the workload in the QA team and let team members collaborate. Ocean Central was first released in 2012.

Analyses available in Ocean 2014 Professional

  • Accuracy
    Evaluates the accuracy of measured parameters. It calculates the deviation between a measured value and a set value (reference value) and compares against specified pass/fail criteria.
  • Reproducibility
    Evaluates the reproducibility of measured parameters. It calculates the difference from mean value, coefficient of variation and standard deviation.
  • mA linearity
    Evaluates the mA linearity. It compares the mA/exposure value of the different mA stations. It can be used with mA/time and mAs generators.
  • HVL
    Calculates half-value layer based on a number of exposures with increasing added filtration. Calculated half-value layer is compared to specified pass/fail criteria.
  • Quick HVL
    Compares the direct measured half-value layer to specified pass/fail criteria.
  • CTDI
    Calculates CTDI based on five CT dose values measured in different positions in a CT phantom. It calculates CTDI, weighted CTDI and normalized CTDI.
    Calculates the average glandular dose according to the rules specified by ACR, EUREF or IAEA.
  • Min/Max limits
    Compares specified parameter to a high and/or low accepted limit. It can be used with all measured parameters and the user-calculation column.
  • Checklist analysis
    Analyze the result of a checklist - if it passed or failed, how many fails and how many warnings there were.
  • AEC evaluations
    AEC kV compensation, AEC mA compensation, AEC reproducibility, AEC reciprocity, AEC field balance, AEC density correction.
  • Graphs
    This analysis is used to plot two different columns against each other. You can do a line or polynomial fit to your data points. It calculates the Correlation Coefficient and Coefficient Determination and allows you to set your own pass/fail criteria.
  • User calculations
    Build your own calculations for any values in Ocean and apply other analyses such as accuracy, reproducibility and max/min limits.
