Abstract
A probe for an ultrasonic diagnostic apparatus which is used for performing a test upon a subject is provided. The probe includes a case which forms an exterior of the probe, a piezoelectric object which is provided on an inside of the case and which generates an ultrasonic wave, a sound absorbing layer which is provided at a rear surface of the piezoelectric object and which prevents the ultrasonic wave from being delivered to a rear portion of the piezoelectric object, an acoustic matching layer which delivers the generated ultrasonic wave to a subject by matching a sound impedance of the piezoelectric object with a sound impedance of the subject, and a sound lens which concentrates the generated ultrasonic wave and radiates the concentrated ultrasonic wave toward the subject.
Claims11
A probe for an ultrasonic diagnostic apparatus, the probe comprising:
- a case;
- a piezoelectric object provided at an interior portion of the case and configured to generate an ultrasonic wave;
- a backing layer provided at a rear portion of the piezoelectric object and configured to block the generated ultrasonic wave from propagating through and out of a rear portion of the backing layer;
- an acoustic matching layer provided at a front portion of the piezoelectric object and configured to match a sound impedance of the piezoelectric object with a sound impedance of a subject;
- an acoustic lens provided at a front portion of the acoustic matching layer and configured to concentrate the generated ultrasonic wave and facilitate a propagation of the concentrated ultrasonic wave signal toward the subject;
- and
- a pad which is provided at a base member that is detachably mounted to a front portion of the acoustic lens, the pad being configured to directly contact with a skin of the subject,
- wherein the acoustic lens comprises a concave portion configured to facilitate a performance of a diagnosis with respect to the subject along a curved surface of the subject, and includes a variable radius of curvature, and
- wherein the concavity of the concave portion of the acoustic lens is a concavity with respect to the skin of the subject.
