A lesion detecting apparatus for breast image in a rotating manner are provided. A set of breast image in the rotating manner is obtained. The set of breast image in the rotating manner contains sub breast images. The sub breast image is reconstructed, to generating a reconstructed breast image. The reconstructed breast image is compared with the set of breast image in the rotating manner without being reconstructed, to confirm at least one lesion position. Therefore, reviewing a three dimension breast image would be convenient for medical staff, and false positive of detecting lesion would be reduced.本新型創作提出一種旋轉式乳房影像之病變偵測裝置。此方法包括(但不僅限於)下列步驟。取得一組旋轉式乳房影像。此組旋轉式乳房影像包括多張子乳房影像。對這些子乳房影像進行重組,以產生重組乳房影像。比對重組乳房影像以及未重組的旋轉式乳房影像以確認至少一個病變位置。據此,可方便人員檢視三維乳房影像且降低病變偵測的偽陽性。100‧‧‧病變偵測裝置110‧‧‧儲存單元111‧‧‧影像輸入模組113‧‧‧影像重組模組115‧‧‧病變判斷模組117‧‧‧影像品質模組150‧‧‧處理單元
