golden standard:The expert group used the measurement results of optic nerve sheath diameter and pupil without using Auto ONSD+ or Auto Pupil as the gold standard.
Group A (the experimental group proceeds first):The film reader completes the identification of the best frame of the optic nerve In the first stage, the readers completed the identification of the be
after a certain washout period (= 4 weeks), in the second stage, they completed the identification of the best frames of the ultrasound imaging samples without the assistance of Auto ONSD+ and Auto Pu
Group B (the control group proceeds first):In the first stage, the readers completed the identification of the best frames of the ultrasound image samples without the use of Auto ONSD+ and Auto Pupil
experimental group:Measure the optic nerve sheath diameter and pupil size with the assistance of Auto ONSD+ and Auto Pupil.
