The assessment of patch size through the segmentation characteristics and time consumption

Patch Size	Time consumption for one patient	Characteristics of patch segmentation	Assessment
64 × 64	0.9306 s	Too rough, fast	Not considered
32 × 32	1.2909 s	Rough, fast	Bad choice
16 × 16	2.6340 s	Including other tissues such as fat, tumor and heart	Bad choice
4 × 4	25.8358 s	Exquisite, but computationally expensive	Second choice
2 × 2	98.0321 s	Very exquisite, but computationally expensive	Bad choice
8 × 8	7.5695 s	Exquisite	Best choice
