Abstract

PURPOSE: To make it possible to obtain high-precision and high-reliability cardiac image data, by removing only cardiac image data for the irregular heart from image data for elapse.
CONSTITUTION: Electrocardiogram signal A has P wave, Q wave, and R wave, and one cardiac pulsation section (b) is divided into five equally (divided into an odd from R wave) and is imaged for each of segments (C), (D), (E), (F), and (G). MDBF.1 is the first magnetic disc memory and can store data of respective five- divided cardiac pulsations, and MDBF.2 reads data written to cores A and B and writes this data to respective segment bands. For example, if irregularity (e) is generated in segment band (E) of one cardiac pulsation in the figure, a pulse is generated by this irregularity, however, the irregular pulse is ignored because addition has been performed on a basis of R wave at this time, and data are read from the memory (MDBF), where data are not added, and are added in the next cardiac pulsation, and therefore, cardiac image data are not affected by arrhythmia at all.
