Background/Introduction
Reducing Radiation Dose to Promote Patient Safety
In ionizing radiation-based medical imaging,
there is a clear link between radiation dose and image quality.
However while higher dose leads to better imaging,
an increased use of ionizing radiation is harmful to both the patient and clinician.
Because of this,
the industry has worked hard to find ways to improve image quality that do not increase further risk to the patient or the clinician.
There is not a simple solution—since there is a constant need for optimization...
Description of activity and work performed
ContextVision’s GOPView iRV Family
ContextVision’s GOPView iRVultra product enables real-time (30 fps) image enhancement in interventional radiology.
It represents a new model of interventional radiology image enhancement with the ability to reduce noise and simultaneously preserve or enhance desired image features,
such as subtle pathology,
vessel edges,
stents,
catheter tips and guide wires in real time.
Since GOPView iRVultra uses an anisotropic (directional dependent) adaptive filtering on a pixel by pixel basis,
there is also no blurring or distortion of key pathology.
The success of...
Conclusion and Recommendations
Maintaining Image Quality and Reader Confidence with Adaptive Filtering
Research conducted at Johns Hopkins University aimed to test and determine the efficiency of a novel,
real-time imaging adaptive filter that can be applied during interventional radiology procedures on a porcine model.
The goal was to identify this technology as a means for improving image quality without the need to manipulate radiation dose.
The study utilized a novel real-time adaptive filter like ContextVision’s GOPView iRVultra .
A real-time electronic dosimeter was placed for entrance skin dose...
