Ultrasonography Training Simulator ver2

Abstract


 Ultrasonography is used in many clinical fields because it is a noninvasive examination with no risk of radiation exposure and can acquire images of various parts of the body from any angle. Although ultrasonography is difficult to master because it depends on the examiner's ability, the problem is that adequate training is not provided. Ultrasound equipment and phantoms, which are human models used for training, are very expensive, and the time available to students is limited, so training during school is rarely provided.

 To solve this problem, we are developing the ultrasound training simulator that can be used to train beginners (medical , medical laboratory science, or radiology technologist cource students). In this study, we specifically focused on the development of a simulator for training abdominal ultrasonography that can be used for home-training.

 This simulator consists of a probe-shape controller and a PC. Doctors and technologists at Teikyo University School of Medicine cooperated in the effectiveness evaluation experiment, and the simulator was highly evaluated.

Configuration


 The probe-shape controller needs to measure the position and posture to operate the virtual probe on the display. Therefore, the position is acquired by an optical mouse sensor and the posture by the IMU.

 The virtual probe and the human body model are displayed, and the virtual probe is operated on the human body based on the position and posture information acquired by the controller. Z-anatomy, open-source 3D model was used for the human body model. In addition, Cross-sectional image of organs are displayed according to the position and posture of the virtual probe, allowing the user to learn how organs look and are arranged in the cross section and how the organs change in appearance due to probe manipulation.
