evaluating 3d-printed models of coronary anomalies: a survey among clinicians and researchers at a university hospital in the uk

by:Tuowei     2019-09-07
【Abstract】 objective evaluation 3-dimensional (3D)
The model of coronary artery abnormality was printed according to cardiac CT data and its clinical application potential was explored.
Design of cardiac CT data sets for patients with various coronary artery abnormalities (n=8)
Review and deal with it, and rebuild it in-
House with desktop 3D printer (
Form 2, Formlabs)
Use white resin.
University Hospital (
Department of Cardiology)in the UK.
Participants performed a CT scan first, followed by a 3D scan
A printed model was presented to the panel of clinicians (n=8)
Cardiovascular Researchersn=9).
Intervention participants were asked to evaluate the different features of the 3D model and rate the overall potential usefulness of the model.
Based on the clarity of anatomical details, insight into coronary artery abnormalities, the usefulness of overall perception, and comparison with CT scans, the resulting measurement model was rated.
Evaluating model features using Likert-Question type (5-
From \"strongly disagree\" to \"strongly agree \")or a 10-point rating (
From 0, lowest, to 10, highest).
The questionnaire includes a feedback form summarizing the overall usefulness.
Student Video Experience (
A few years later)
It was also recorded.
Results all the models were reconstructed and printed successfully. the accurate details showed the coronary anatomy (
For example, abnormal coronary artery, coronary roof, or coronary artery aneurysm in Kawasaki syndrome patients).
Feedback was provided by all clinicians and researchers, and both groups found models that helped to show coronary anatomy and abnormalities and complement the View 3D CT scans.
The panel of clinicians with more imaging expertise provides a more enthusiastic rating on the clarity, usefulness and future use of the model. Conclusions 3D-
The printed heart model can be used to reconstruct the anatomical structure of the coronary artery and enhance the understanding of coronary artery abnormalities.
Future research can assess their costs.
The effect, and it is possible to explore other printing techniques and materials.
