Abstract: An ultrasound diagnosis apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to detect a saturation region of a signal based on an ultrasound wave received by an ultrasound probe; and to correct a first signal including an odd-numbered order harmonic component of the saturation region, on a basis of a second signal including an even-numbered order harmonic component of the saturation region.

Abstract: According to one embodiment, an ultrasonic diagnostic apparatus includes an ultrasonic probe and processing circuitry. The processing circuitry receives a reflected wave signal of an ultrasonic wave via the ultrasonic probe. The processing circuitry generates a reception signal based on the received reflected wave signal. The processing circuitry calculates blood flow information based on the reception signal. The processing circuitry detects a magnitude of blood flow velocity change based on the blood flow information calculated at a plurality of points in time. The processing circuitry performs smoothing processing on the blood flow information in time direction at an intensity determined in accordance with the detected magnitude of blood flow velocity change.

Abstract: The present invention provides a method for purifying carbon dioxide gas characterized in that carbon dioxide gas containing at least one of 3-methylmercaptopropionaldehyde and acrolein is contacted with activated carbon to remove at least one of the 3-methylmercaptopropionaldehyde and acrolein. The present invention provides also a method for producing methionine comprising the purification step of the recovered carbon dioxide.

Abstract: A method and system enable to-be-processed medical image data and its corresponding noise characteristic information to be normalized to resemble noise characteristic information of training data used to train at least one neural network for at least one ultrasound data acquisition mode. After normalizing, this processed medical image data is input into the trained neural network for producing output data used for generating cleaner images. Noise characteristic information can be used directly in training a neural network, generating a trained neural network that can handle medical image data with various noise characteristics.
