目的 对数字减影血管造影(digital subtraction angiography,DSA)图像进行处理,获取肝脏肿瘤的供血血管图像,为肿瘤介入栓塞治疗提供依据,并对栓塞效果进行评价。方法 在MATLAB平台上,分别对治疗前、治疗后及肿瘤图像进行处理,获得肝脏肿瘤供血的血管图像和治疗后的肝脏血管图像。结果 实现了肝脏肿瘤、肝脏肿瘤供血血管和肝脏血管图像的提取。结论 对于随机抽取的DSA图像,该方法可获得理想的肝脏血管图像和为肝脏肿瘤供血的血管图像,可为临床医生的治疗提供依据,还可为科研及教学服务,具有一定的实用价值。
Abstract
Objective: To obtain the blood supply vessels of the liver tumor through processing the digital subtraction angiography (DSA) image, and to provide the clinical treatment basis for the detection of tumor interventional therapy and embolization. Methods: The tumor images, the blood vessels and liver vessels were obtained before and after being processed on the MATLAB platform . Results: The extraction of liver tumor, blood supply vessel of liver tumor and blood vessel of liver were realized. Conclusion: For randomly selected DSA images, this method can obtain ideal liver blood vessels and blood vessels for liver tumors, which can provide basis for the treatment of clinicians, and serve for scientific research and teaching.
