摘要：
An evaluation system includes a magnetic resonance imaging system, an operation unit, a self encoder and a storage unit.The MRI system can scan multiple whole brain images with multiple b values,The computing unit analyzes each whole brain image,To obtain the corresponding general diffusion wave number sampling contrast (gqi),The arithmetic unit calculates one index value of each voxel for each gqi,The self encoder features the values of each gqi to obtain a corresponding compressed image,The operation unit classifies each compressed image according to a machine learning model of the compressed image whose corresponding index values are extracted by features,To evaluate whether the corresponding user has suicidal ideation,It can help to evaluate and judge whether the user is a melancholic patient with suicidal ideation.一種評估系統，包含一磁振造影系統、一運算單元、一自編碼器、及一儲存單元。該磁振造影系統掃描獲得在多個b值的多個全腦影像，該運算單元對每一該全腦影像作分析，以獲得對應的一通用擴散波數取樣造影(GQI)，該運算單元對每一該GQI計算每一體素(Voxel)的一指標值，該自編碼器對每一該GQI的該等指標值作特徵擷取以獲得對應的一壓縮影像，該運算單元根據對應該等指標值經特徵擷取的該等壓縮影像的一機器學習模型對每一該壓縮影像作分類，以評估對應的一使用者是否具有自殺意念，而能夠輔助評估與判斷該使用者是否是具有自殺意念的憂鬱症患者。
