CPC A61B 8/5276 (2013.01) [A61B 8/14 (2013.01); G01S 7/52077 (2013.01)] | 10 Claims |
1. An ultrasound diagnosis apparatus comprising:
processing circuitry configured:
to sequentially obtain eigenvalues of a correlation matrix of a scan range, the correlation matrix being obtained from a data sequence of reflected-wave data in a mutually same position acquired by performing an ultrasound scan on the scan range formed with a plurality of scanning lines; and
to determine a filter coefficient to be applied to a Moving Target Indicator (MTI) filter, on a basis of the plurality of eigenvalues obtained at mutually-different points in time, wherein
the processing circuitry
identifies a minimum value of an eigenvalue among the plurality of eigenvalues in a predetermined time period from a present time to a time that is a predetermined time earlier than the present time,
calculates a difference between the minimum value and an eigenvalue at the present time, and
determines the filter coefficient based on the difference.
