Abstract: A signal processing apparatus includes a memory, and a processor coupled to the memory and configured to perform a process including obtaining measurement data including a signal of interest and an interference signal generated in proximity to a signal source of the signal of interest, estimating a signal source in an extraction target area including the signal source of the signal of interest and a signal source of the interference signal based on the measurement data, selecting the signal source of the interference signal based on a result of the estimating a signal source and extracting interference signal data generated from the selected signal source of the interference signal, and extracting the signal of interest by removing a common part between the measurement data and the interference signal data.

Abstract: A biomagnetic measurement apparatus includes a table on which a subject is placed; a biomagnetic detector configured to detect a biomagnetic field of the subject; a supporter configured to support a detection target region from which the biomagnetic field of the subject is detected; a radiation detector provided below the supporter; and a position changer configured to change relative positions of the biomagnetic detector and the detection target region. The supporter has a surface shape that corresponds to a surface of the biomagnetic detector.

Abstract: A biomagnetic measurement method, a biomagnetic measuring device, and a biomagnetic measuring system. The method and the biomagnetic measuring device includes obtaining first measurement data output from a magnetic field detector upon giving a stimulus to a subject in a first state where a site of interest of the subject is made close to the magnetic field detector, and obtaining second measurement data output from the magnetic field detector upon giving a stimulus to the subject in a second state where a site to which the stimulus is given and a position of the site to which the stimulus is given are equivalent to a site to which the stimulus is given and a position of the site to which the stimulus is given in the first state, respectively, and the site of interest of the subject is separated from the magnetic field detector with reference to the first state.

Abstract: A distance image processing device, a distance image processing method and a distance image processing program according to the present invention obtain a distance image having a plurality of pixels corresponding to each of a plurality of directions different from each other based on a plurality of transmitted waves and a plurality of reflected waves and determine a target region as noise if a gradient of a distance value between the target region and a predetermined peripheral with respect to the target region is within a predetermined range and a pulse width of the reflected wave relating to the target region is larger than a pulse width of the reflected wave relating to the peripheral region when a predetermined region in the distance image is the target region. A recording medium records such a distance image processing program.

Abstract: A biological information measuring apparatus includes a biomagnetism detector configured to detect biomagnetism of a subject, the biomagnetism detector including a temperature adjustment mechanism; and a radiation detector configured to acquire emitted radiation as digital image data. The radiation detector is disposed between a measurement region of the subject and the biomagnetism detector.
