Phase correlation and then reaches image mosaic by graph cut and poisson image fusion.graph cut is used to find a globally optimized seam-line for deghosting while poisson image fusion is used to realize smooth mosaic without exposure difference.a new weight calculation method based on the statistics of guadient direction histogram is presented here in order to robustly realize graph cut.an edge transition poisson image fusion method is also proposed to reach exposure difference removal

该方法在相位校正的基础上将图切割和泊松融合相结合实现拼接，图切割用于搜索全局最优的缝合线以去除鬼影，泊松融合用于曝光差异的处理。本文给出新的基于梯度方向直方图统计的权值计算方法，实现稳定的图切割。另外，本文还设计出重叠过渡的泊松融合方法，较好地完成图像合成。

Results: In the abdomen and chest Xray, the features of aute pancreatitis included sentinelloop dilatation (15 cases), vaulted impression in duodenal flexure (1 case), hyperdense imaging in the area of pancreas (1 case), paralytic ileus (2 cases) and hydrothorax (2 cases).

结果：急性胰腺炎胸腹部X线平片显示反射性肠郁积15例，十二指肠曲部见弧形压迹1例，剑突下胰腺区高密度影1例，麻痹性肠梗阻伴胸腔积液2例。

Barium agent enter the hypophragmatic gastral cavity circumferencely, multi-directions showed the verge of esophagous hiatal hernia sac were smooth and intact extremely. There were imaging of fine line between the filling defect and the wall of hiatal hernia sac. The superior border of filling defect could be described as "pointed top" in 3 cases, while "round top" in 4 cases.

钡剂沿着充盈缺损的疝囊周壁进入膈下胃腔，多方位旋转显示疝囊轮廓边缘十分光滑且完整，其内充盈缺损与疝囊壁之间存在薄而完整的钡线影。3例充盈缺损的上缘表现为&尖顶征&，4例&圆顶征&。

The fistula could be diagnosed correctly when the patient suffered high fever, dyspnea and thoracalgia after operation, with cervical anastomotic external fistula which could not been healed when the wound was opened, X-ray-showed widened mediastinum and hydropneumothorax, and drainage, esophagoraphy and CT-confirmed anastomotic fistula.

当出现术后突发的高热、呼吸困难、胸痛，合并颈部吻合口外漏，经敞开后病情无好转，X线见纵隔影增宽，液气胸，经口服美蓝，食管造影和CT检查发现吻合口内瘘入纵隔或胸腔即可确诊。
