摘要：
The present invention relates to a magnetic resonance spectroscopic signal pre-processing apparatus which obtains processed data by pre-processing magnetic resonance spectroscopic signal to extract information of materials in a human body from the processed data obtained by pre-processing the magnetic resonance spectroscopic signal obtained with respect to a human body. The magnetic resonance spectroscopic signal pre-processing apparatus comprises: a fourier conversion unit which performs fourier conversion from data in a time area into data in a frequency area of the magnetic resonance spectroscopic signal obtained with respect to a human body； a differential filter application unit which removes a signal, which is not the information of materials in a human body to be analyzed, by applying a differential filter to the magnetic resonance spectroscopic signal of the fourier-converted frequency area； and an abs application unit which applies an absolute value function to the signal to which the differential filter has been applied. Accordingly, the magnetic resonance spectroscopic signal pre-processing apparatus can perform, in an easy manner, acquisition or deletion of data of a metabolism material as an analysis target which a user desires to obtain from a magnetic spectroscopic signal, correct distortion of a base line from a water signal or a fat signal, detect correct data in an easy manner without distortion of the signal due to an absolute value which is not related to a phase value, has an effect of increasing the ratio of noise to a signal, and increases correctness of a metabolism material quantitative analysis with respect to an acquired signal.본 발명은 자기공명분광신호 전처리 장치에 관한 것으로서, 인체에 대해 획득된 자기공명분광신호를 전처리한 가공 데이터로부터 인체내 물질정보 추출을 위하여 상기 자기공명분광신호를 전처리하여 상기 가공 데이터를 얻는 자기공명분광신호 전처리 장치에 있어서, 상기 인체에 대해 획득된 자기공명분광신호를 시간 영역의 데이터에서 주파수 영역의 데이터로 퓨리에 변환하는 퓨리에 변환부； 퓨리에 변환된 주파수 영역의 자기공명분광신호에 차등필터를 적용하여 분석대상 인체내 물질정보가 아닌 신호를 제거하는 차등필터 적용부； 그리고 차등필터가 적용된 신호에 절대값 함수를 취하는 abs 적
