Aims and objectives
1.Aims and objectives
Contrast-enhanced CT (CECT) with iodinated contrast agent is a typical imaging examination for definitive diagnosis and is indispensable.
It is known that the iodinated contrast agent causes side effects with a certain probability,
and the operator is required to correctly perform the injection technique of the contrast medium.
For injection of the contrast agents,
an automatic injector dedicated to CT is used.
In general,
the information of the CT scanners and the injector are linked by a standardized communication standard (controller area...
Methods and materials
2.Methods and materials
2.1.Target examination
In this study,
we collected operator's gaze for CT contrast 1-phase examination from chest to pelvis.69 cases were collected,
37 cases with CAN 4 and 32 cases without CAN 4.
2.2.
Target and equipment
Five medical radiological technicians (working experience 3 to 11 years,
average 8 years) who understood the operation contents and the flow of the inspection operated.
Combinations of CT scanner and injector are Aquilion ONE Vision (ver.
7.0: Canon Medical Systems,
Inc.,
Nasu,
Japan) and GX 7...

Results
Fig.4 shows gaze time and gaze ratios in each range with and without CAN 4.
Fig.5 compares Gaze Plot with and without CAN 4.
3.1.Total gaze time
The total gaze time was 273.9 ± 39.7 seconds with CAN 4 and 274.5 ± 44.1 seconds without CAN 4.
There was no statistically significant difference (P = 0.78> 0.05).
3.2.S-con monitor
The gaze time of the S-con monitor was 130.6 ± 33.9 seconds with CAN 4 and 115.1 ± 35.2 seconds without CAN 4.

Conclusion
4.Conclusion
In this study,
we focused attention on the gaze distribution during CT imaging and scientifically analyzed the introduction effect of the CAN 4.
This result of this study suggested that CAN 4 could help operators to focus more of their time on the CT console or the patient during contrast-enhanced CT examinations.
Take advantage of the CAN 4 is medical safety directly connected.
Also,
sight line analysis can be utilized in various scenes.
