The processing circuitry is configured to apply a filter to each of a first real-part image and a first imaginary-part image of a first complex image generated based on acquired magnetic resonance data and thereby generate a second complex image that includes a second real-part image and a second imaginary-part image. The processing circuitry is configured to generate a phase image denoised by the filter, the denoised phase image generated based on the second real-part image and the second imaginary-part image. The processing circuitry is configured to generate an intensity image related to an absolute value of the first complex image based on pixel values of the denoised phase image, the first real-part image, and the first imaginary-part image.

  • Patent number: 10695087
    Abstract: An apparatus (51) includes a needle placement manipulator (1) and an attachment (52) for the manipulator. The manipulator includes a needle holder and a rotary mechanism. The rotary mechanism (3, 4) has a remote center of motion (RCM: 11) and is configured to position a needle holder (5) such that the axis of the needle holder traces a conical region of coverage (108), the conical region of coverage having the apex thereof at the RCM and the base thereof in a direction towards a subject of needle placement (14). The attachment supports the guide mechanism and is configured to be mounted onto the subject of needle placement. The attachment includes a guide portion (183c) configured to change an inclination of the rotary mechanism with respect to the subject of needle placement such that the axis of the needle holder intersects an insertion target (14) located outside of the conical region of coverage.

  • Patent number: 10695799
    Abstract: A control method for a vibration-type actuator which prevents the vibration-type actuator from becoming inoperable during operation. To drive the vibration-type actuator when a load for moving a vibrating body and a driven body relatively to each other is relatively high, a first frequency falling within a frequency range including a frequency at which thrust of the vibration-type actuator reaches its peak is set as a starting frequency of AC voltage applied to an electro-mechanical energy conversion element of the vibrating body. To drive the vibration-type actuator when the load is relatively low, a third frequency lower than the first frequency and higher than a second frequency is set as the starting frequency, the second frequency being a frequency at which a moving speed at which the driving body and the driven body move relatively to each other reaches its peak.
