摘要： The present invention provides a suspension polymerization method for producing a polymerized particle having cavities in the particle. The method includes the steps of: placing a continuous phase component of an aqueous medium in a continuous phase vessel and a dispersed phase component composed of a monomer composition and a liquid noncompatible to the monomer composition, wherein the liquid noncompatible to the monomer composition is suspended in the monomer composition, in a dispersed phase vessel; subsequently supplying continuously and simultaneously each of the dispersed phase component and the continuous phase component to an apparatus for providing a shear force; subsequently exerting a shear force on the dispersed phase component and the continuous component to form a suspension material including polymerizable liquid-drops of a desired size; subsequently leading the suspension material to a polymerization vessel; subsequently subjecting the suspension material in the polymerization vessel to a polymerization reaction to form a polymerized material; and subsequently drying the polymerized material to obtain the polymerized particle having the cavities in the particle.

摘要： A diagnostic ultrasound system comprising an element for detecting a velocity of motion of a tissue, such as a cardiac muscle or a vascular wall, contained in an object at every sampling point in a section of the object and an element for creating two-dimensionally mapped data of the velocity in the section. The system further comprises an element for analyzing a motion state of the tissue on the basis of local velocities falling into a plurality of local regions set on the two-dimensionally mapped data of the velocity and an element for displaying analysis results of the motion state. The velocity detecting element transmits an ultrasonic pulse signal toward the tissue in order to acquire a Doppler shifted echo, according to a pulsed Doppler technique.
