Development and clinical usefulness of concave ultrasonic transducer

The usefulness of a concave ultrasonic transducer in evaluating convex shaped organs is investigated. Ultrasonic images of 126 cases of the transducer of 5-9 MHz are compared with those of linear array transducer of 5-9 MHz. The width of the field view, discriminative ability of interpretation of hi...

Zusammenfassung:The usefulness of a concave ultrasonic transducer in evaluating convex shaped organs is investigated. Ultrasonic images of 126 cases of the transducer of 5-9 MHz are compared with those of linear array transducer of 5-9 MHz. The width of the field view, discriminative ability of interpretation of histologic location of the lesion and surrounding tissue, diagnostic accuracy, distortion of images according to location and degree of compression between the transducers are analyzed.
