Osteoid osteomas usually occur in the axial skeleton (especially tibia and femur) in bone cortex of young males in the second decade of life.
骨样骨瘤常见于十几岁男性中轴骨骼(尤其是胫骨和股骨)的骨皮质。
Further processing of resulting boundary with binary morphological operation produces a closed osteomas contour. So osteomas is isolated from background.
最后利用二值形态运算进一步处理，便可得到封闭的骨肿瘤边界，从而将骨肿瘤与背景分离。
