title: Ultrasonic characteristics of leiomyoma uteri in vitro.
abstract: Patients suffer with various abnormalities of body tissues. "Leiomyoma Uteri" is a solid tumor of uterus, one of such abnormalities. To treat such tumors, basic physical and biologic investigations are required to be carried out. In the present work, ultrasonic characterization of soft tissues, in this case, uterine tumor in vitro, are studied. A double probe through-transmission technique is used for the measurement of these propagation parameters, viz., velocity and attenuation. Other parameters like acoustic impedance, dynamic modulus of elasticity and compressibility are also determined. The average velocity and attenuation are found to be 1550 ms(-1) and 433 dBm(-1), respectively, at 3.5 MHz frequency and room temperature 28 degrees C. The present investigation is useful in tissue differentiation and tissue identification to enable the doctors to give proper treatment.
