The guide output means 1200 is a body part (hereinafter referred to as 'measurement site') where the measurement probe 31 should be placed to view the organ of the patient 10 corresponding to the item selected in the practice item selection window 40. (referred to as ,) is displayed to guide the user.

For example, when the practitioner (1) selects an item related to a disease in the practice item selection window (40), the guide output means (1200) is configured to enable the patient (1200) to view an ultrasound image of an organ related to the disease ( Mark and guide the measurement area in 10).

In addition, the guide output means 1200 implements a guide model (G) of the same shape as that of the measurement probe 31 to guide the measurement probe 31 and outputs it to the measurement site of the patient. The guide model (G) is output to have the optimal angle and tilt to obtain an accurate ultrasound image at the relevant measurement site.

Meanwhile, in order to clearly and accurately image the organs inside the human body, the actual ultrasound examination not only places the measurement probe on an appropriate body part where the ultrasound image for each organ can be viewed, but also places the measurement probe at an appropriate body part, Tilt is also important.

However, in the case of conventional practice simulation programs based on virtual reality, the patient's body part is specified for the area to be operated or examined and the practice equipment or instrument for the corresponding body part is simply displayed so that it can be located.
