  • Patent number: 11213212
    Abstract: An apparatus for measuring blood pressure, and a method for measuring blood pressure by using the same are disclosed. The disclosed method for measuring blood pressure comprises the steps of: calculating pulse wave transit time; measuring vascular compliance; and measuring systolic blood pressure and diastolic blood pressure by using the pulse wave transit time and the vascular compliance, wherein the vascular compliance can be measured respectively in at least two or more different hand shape poses.

  • Patent number: 10456115
    Abstract: An ultrasound system and a clutter filtering method thereof are provided. The clutter filtering method includes: transmitting an ultrasound signal to an object; receiving a reflection signal reflected from the object; performing a singular value decomposition (SVD) on a plurality of doppler signals constituting the reflection signal; dividing a representation of the object into a plurality of regions according to a result of performing the SVD; determining cutoff frequencies of the plurality of regions according to different methods; and performing clutter filtering on the plurality of regions by using the determined cutoff frequencies.
