  • Patent number: 11865371
    Abstract: Apparatuses and methods to generate high frequency shock waves in a controlled manner. The generated shock waves can be delivered to certain cellular structures of a patient for use in medical and/or aesthetic therapeutic applications. The shock waves can be configured to impose sufficient mechanical stress to the targeted cells of the tissue to rupture the targeted cells. Embodiments of the apparatuses and methods of the present invention provide targeted rupturing of specific cells without damaging side effects such as cavitation or thermal degradation of surrounding non-targeted cells.

  • Patent number: 11547390
    Abstract: Information relevant to a state of a tissue in a subject (state information) is provided with technology reducing the amount of memory and computation necessary at the time of extracting the information. An ultrasonic wave is transmitted towards a subject, a transmission wave transmitted through the subject or a reflection wave reflected on the subject is received. A reception signal is generated on the basis of the transmission wave or the reflection wave. A tissue region candidate, of a region indicating a tissue of the subject, is set on the basis of the reception signal. State information, which is information relevant to a state of the tissue in the tissue region candidate, is calculated on the basis of the reception signal and the tissue region candidate. An ultrasonic image reflecting the state information is generated on the basis of the state information and displayed.

  • Patent number: 11378638
    Abstract: An echo planar imaging technique in which a quadruple echo gradient and spin echo echo-planar imaging pulse sequence is utilized. The pulse train includes generation of two echo trains between an excitation pulse (90) and a refocusing pulse (180) to achieve two gradient echo images (also called T2*-weighted images); with one echo train directly after the 180 pulse, leading to asymmetric spin echo images (T2?-weighted images); and a last echo train afterward that generates spin echo images (T2-weighted). The technique has a number of advantages over existing techniques with regard to voxel size, mapping relative oxygen extraction, determining permeability, determining relative cerebral blood volume, vessel parameters (diameter, density, size, arterial/venous, etc.), stroke imaging, imaging perfusion, fMRI imaging, and additional benefits.
