Fig.3

Ultrasound images of two artificial solid tumors made of olive and carrot pieces to represent oval inhomogeneous lesions. Olive flesh appeared as a mildly hyperechoic area at the edge of the lesion, while carrot pieces appeared as a hypoechoic area in the middle portion with a posterior shadow and several small linear hyperechoic areas.

Fig.7

A water-filled balloon was used to mimic a cystic lesion. This ultrasound image demonstrated the cystic lesion as a well-defined, oval-shaped anechoic area with posterior enhancement.
