A novel measure method of cerebral hematoma volume

Cerebral hematoma is one of common brain diseases, and its treatment is mainly determined by estimation of hematoma volume and positions. While unfortunately, widely-used Tada formula is founded base on the assumption that the blood clots are ellipsoid but irregular in practice. This paper proposes a novel measure method for the estimation of cerebral hematoma volumes by CT images. This method can be divided into three steps: remove noises in original images by edge detection and thresholding segmentation; then separate skull and blood clots by region growing method, and finally calculate hematoma volume by gengon and truncated pyramid approximations. A demonstrated case also shows the feasibility and efficiency of the proposed method, which can provide a more accurate basis for clinical treatment of cerebral hematoma.
