  • Patent number: 11000204
    Abstract: The present invention relates to a device and method for reconstructing low-frequency conductivity images using MRI without current injection. In the device according to the present invention, low-frequency conductivity is deduced using high-frequency conductivity obtained using MR-EPT, the calculated directional tensor of ions from the water diffusion tensor in a subject, and the volume fractions and diffusion coefficients of the intracellular/extracellular spaces, and low-frequency conductivity images are reconstructed based on the deduced low-frequency conductivity. According to the present invention, low-frequency conductivity images in a subject to be measured such as the human body and an object may be reconstructed using an MRI device without applying current to the subject.

  • Patent number: 10874310
    Abstract: In illustrative implementations of this invention, a photoplethysmographic device measures variations of light that is reflected from, or transmitted through, human skin. In some implementations, the device includes a camera that takes the measurements remotely. In others, the device touches the skin during the measurements. The device includes a camera or other light sensor, which includes at least orange, green and cyan color channels. In some cases, such as a contact device, the device includes three or more colors of active light sources, including at least orange, green and cyan light sources. A computer analyzes the sensor data, in order to estimate a cardiac blood volume pulse wave. For each cardiac pulse, a computer detects the systolic peak and diastolic inflection of the wave, by calculating a second derivative of the wave.
