Eye Phantom

Biometric measurements with ultrasound are an important diagnostic method in ophthalmology. The typical biometric measurements of the length of the eye axes are excellently suitable for demonstration of the fundamentals of ultrasonic pulse-echo applications. With this phantom and the ultrasonic echoscope GS200 (order no. 10400) with a 2 MHz probe (order no. 10152) one receives echoes that are typical of the eye. The eye consists of a lens and the vitreous body with different sound velocities. The geometric dimensions of these objects can be determined by the distance of the echoes. In addition, an injury with a diffuse echo structure close to the fundus of the eye can be detected.
