The process of virtual-assisted lung mapping (VAL-MAP). (A) We established a road map of VAL-MAP on paper. This image shows the resected margins for the GGO; (B) we show an example of the virtual bronchoscopy images for the mappings; (C) the PostMapping CT image. The circles indicate the mapping points; (D) the PostMapping CT image reconstructed into a three-dimensional image. The arrows indicate the planned line of resection. GGO, ground-glass opacity.
