Abstract
The prototype three-dimensional ultrasonic probes are developed to improve the mobility and visibility. We study a comparative ultrasonic visibility with prototype and conventional probes.
113 cases of gastrointestinal lesions were examined with either prototype and/or conventional probes.
The rate of surface rendering image (SRI) in 83 cases except for stricturing lesions is 84.3% (84.6% in upper vs 84.1% in lower digestive tract diseases) .
Even if the distance between the center of the probe and the surface of the lesion is shorter than 4mm, we were able to get the ultrasonic SRI of the lesion by the prototype probes.
No significant difference was noted between the prototype and conventional probes in terms of the penetration depth.
In conclusion, the prototype probes could construct the SRI of the lesion scanning with optimum distance between the probes and the lesion, being closer than the conventional probes.
