Abstract

The present invention provides a method and system for visualizing fetal heart rate data of a multi-dimensional channel sensor, including: collecting multiple dimensions of fetal heart signal data through a multi-dimensional channel sensor; projecting the fetal heart signal data into one-dimensional, two-dimensional or Three-dimensional space; the projection includes any one or more of the following: projection, clustering, principal component analysis and integral processing. The invention uses a multi-dimensional channel sensor to suppress interference noise, increases the amount of measured information, and uses dimensionality reduction information to visually display information. The use of dimensionality reduction information can not only simplify the display of existing information, but also dig out the information hidden in the data before. For example, the projection of space dimension and frequency dimension will display fetal movement, fetal position and other information.

Description

technical field [0001] The invention relates to the field of data visualization, in particular to a method and system for visualizing fetal heart rate data of a multi-dimensional channel sensor. Background technique [0002] Patent documents US4086917A and US4890624A both disclose fetal heart rate monitoring methods based on ultrasonic transmitters. This method was later widely used. The basic principle is to transmit signals to the abdomen of pregnant women, and the ultrasonic signals will produce reflections when they pass through different parts of human tissue. When the ultrasonic signal encounters the fetal heart, it will also be reflected, and this reflection will produce a Doppler frequency shift due to the motion characteristics of the target. By observing the speed of frequency offset change, it can be used to analyze fetal heart rate data. [0003] This kind of fetal heart rate monitoring method based on ultrasonic emission is still in use today. The main proble...
