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 network: CAN,
ISO 11898),
and in recent years the CT scanners has become able to read and write the information of the injector.
The classification of CAN is shown in the Fig.
1.
That is,
in CAN class 4 (CAN 4),
the CT scanners manages the injection condition setting and the injection condition in real time.
As a result,
the operation by the operator is simplified and it is possible to carry out the contrast-enhanced CT efficiently.
Fig.
2 shows effect and workflow with or without CAN 4 in CECT.
However,
the effectiveness of CAN 4 has not been quantitatively evaluated.
Therefore,
we focused attention on the operator's gaze during CECT.
The purpose of this study is to verify the effect of CAN 4 at the time of CECT based on the operator's gaze analysis.
