In an ultrasonic diagnosis device composed of ultrasonic optical elements arranged to be disposed in a mass of fluid in a container together with the object to be examined in order to image the object in an image plane, a source of incoherent sound radiation for irradiating the object, a condenser lens, an imaging objective and an acoustic energy detector system, the incoherent sound radiation source is composed of a turbulence chamber containing a plurality of particles arranged to move essentially randomly relative to one another, and at least one ultrasonic transmitter for irradiating the particles in the turbulence chamber with coherent ultrasound; the imaging objective is composed of at least two individual lenses of homogeneous material which are arranged in symmetry to one another and each having lens face which faces the other lens and which has an aspherical shape; and the detector system is composed of a linear array of detectors for converting the resulting ultrasound image of the object into electrical signals, and a unit for periodically moving the detectors across the image plane.

Ultrasonic diagnosis device

In an ultrasonic wave transmitter for generating spatially incoherent ultrasonic radiation, which transmitter includes a source of ultrasonic acoustic radiation, there are provided a member holding a fluid medium in a region exposed to the acoustic radiation, a plurality of particles immersed in the medium and having a diameter of the order of magnitude of the wavelength of the acoustic radiation and an acoustic radiation impedance different from that of the medium, and a device for subjecting the particles to an irregular movement in the medium and within the region.
