20080208054 | ULTRASONIC IMAGING APPARATUS - An ultrasonic imaging apparatus, detecting a signal peculiar to a contrast agent emitted when liquid formed in a fine particle vaporizes due to ultrasonic waves and imaging space distribution thereof. A narrow band is used for transmission, a broad band is used for a received signal, and in a state of high space resolution of the received signal, a transmission signal and the received signal are discriminated. | 08-28-2008 |
20080311046 | Ultrasound Contrast Agent - An ultrasound contrast agent composed of at least one kind of low-boiling water-insoluble substance (with a boiling point lower than 37° C.) and at least one kind of high-boiling water-insoluble substance (with a boiling point higher than 37° C.). The former vaporizes to absorb ultrasonic energy upon application of ultrasound, thereby causing the latter to vaporize secondarily, with the resulting bubbles producing an echo image. It is less liable to bumping and hence safe. | 12-18-2008 |
20080312535 | ULTRASOUND IMAGING SYSTEM - The present invention aims to provide a tissue-function measurement device and a therapeutic device which are not dependent on tissue shape. According to the present invention, the stiffness of a tissue is measured by using, as an index, acoustic variation during the generation of microbubbles from phase-change nano droplets. The acoustic variation is, for example, a duration time of the generation of a harmonic. | 12-18-2008 |
20090010852 | PROCESS AND APPARATUS FOR PREPARING A DIAGNOSTIC OR THERAPEUTIC AGENT - Provided are a preparation process of a diagnostic or therapeutic agent having a step of adding, to a first fine emulsion having a particle size of 0.5 μm or less prepared by applying a predetermined pressure to a first mixture containing a first hydrophobic compound, an emulsifying agent, and an aqueous phase, a second hydrophobic compound compatible with the first hydrophobic compound, thereby preparing a second mixture; and a step of stirring and shaking the second mixture in a hermetically sealed state, thereby embedding the second hydrophobic compound in the first fine emulsion to prepare a second fine emulsion having a particle size of 0.5 μm or less; a diagnostic or therapeutic agent prepared by the process; and an apparatus for carrying out the process. | 01-08-2009 |
20090048516 | IMAGE DIAGNOSING DEVICE - An diagnostic imaging apparatus for imaging information changing with time and displaying it in real time, composed of an ultrasonic probe ( | 02-19-2009 |
20110028835 | ULTRASONIC WAVE IRRADIATION DEVICE - Disclosed is an ultrasonic wave irradiation device usable for the application of a phase change type ultrasonic wave contrast medium, in which any interference between ultrasonic wave irradiation for the phase change application and ultrasonic wave irradiation for treatment application does not occur. An ultrasonic wave with a high frequency and a large magnitude of the maximum negative pressure is used for the phase change application, and an ultrasonic wave with a lower frequency and a large magnitude of the maximum positive pressure is used for the treatment application. | 02-03-2011 |
20120172720 | ULTRASONIC TREATMENT DEVICE - There is provided an ultrasonic treatment device that is minimally-invasive and that achieves embolization treatment having a high blood flow blocking effect. To this end, the ultrasonic treatment device is provided with a function to transmit to a target area of a subject both a bubble generation pulse that vaporizes a contrast agent, and a bubble generation pulse that causes the diameter of the formed bubble to increase. | 07-05-2012 |
20130053691 | ULTRASOUND DIAGNOSTIC AND TREATMENT DEVICE - Provided is an ultrasound diagnostic and treatment device for tumors which is used in combination with a phase-shift ultrasound contrast agent. By using a phase-shift ultrasound contrast agent, irradiating phase-shift ultrasonic waves from a phase-shift ultrasonic wave transmitter ( | 02-28-2013 |
20130261451 | ULTRASONIC MEDICAL DIAGNOSTIC DEVICE FOR IMAGING CHANGES WITH TIME - A diagnostic imaging apparatus for imaging information changing with time and displaying it in real time, composed of an ultrasonic probe ( | 10-03-2013 |
