Interventions
Manual Positioning Experimental Group A:Manual positioning involves changing the position of the thyroid at the shoulder, with the assistance of additional positioning techniques, to reduce artifacts
Manual Positioning Control Group B:Manual positioning involves routine positioning for thyroid examination without any intervention.
Assisted Positioning Experimental Group A:AI positioning involves changing the position of the thyroid at the shoulder, with the assistance of additional positioning techniques, to reduce artifacts ca
