Claim 0:
1. A method for processing pulmonary vein computed tomography (PVCT) images, comprising:
obtaining a plurality of input PVCT images from the upper border of a left atrium to the bottom of a heart;
determining, by a residual network model, whether each of the plurality of input PVCT images relates to a non-pulmonary vein (NPV) trigger origin, wherein a first convolution operation is performed based on the plurality of input PVCT images and a first convolution layer, and a second convolution operation is performed based on a second convolution layer, and
determining the plurality of input PVCT images relating to a NPV trigger origin when more than half of the plurality of input PVCT images are determined relating to a NPV trigger origin,
wherein:
a first filter of the first convolution layer and a second filter of the second convolution layer are determined based on a training set and an internal validation set,
the training set includes a first portion of the multiple patients and the corresponding training PVCT images,
the internal validation set includes a second portion of the multiple patients and the corresponding training PVCT images, and
the internal validation set determines whether the first filter of the first convolution layer and the second filter of the second convolution layer are convergent.
