基于深度残差网络的心脏肿瘤识别和分割研究
Research of Classification and Segmentation of Left Aneurysm Based on Deep Residual Net
Abstract
房壁瘤可以分成两种：一种是先天性房壁瘤，一种是后天生成的房壁瘤。其中先天性房壁瘤是比较少见的疾病，至今国内外有报道的案例不超过50例。房壁瘤多发于左心房的心耳周边。左房壁瘤的瘤体尺寸不定，表面相对较薄，当房壁瘤较大时，瘤体会压迫周遭血管，从而导致缺氧，行动缓慢等一系列症状。如果忽视其带来的影响，后果往往可能致命。因此，在临床上，精确地识别和分割肿瘤对于早期诊断和治疗计划的制定非常重要。然而，对房壁瘤的识别和分割仍然是一项严峻的挑战，主要原因是房壁瘤的尺寸非常小，同时其周遭的环境相当复杂，对于分割算法存在诸多干扰。 为了完成分割肿瘤的任务，需要对心脏CT影像中的肿瘤进行识别。首先对CT影像进行... Atrial aneurysm has two types: the first kind is congenital Left aneurysm, second is acquired generation. The congenital left aneurysm is a pretty rare disease, which has no more than 50 cases in world. Left aneurysm commonly appears in the left atrium, especially in the surrounding of left atrial appendage. At the same time,Left atrium is rarely associated with other complications of cardiac tumo...
