Positioning Scan Method and Apparatus, Dual-Source CT Apparatus, Medium and Product

原文（中国語）

A positioning scan method and apparatus for dual-source CT systems addresses the low working efficiency of existing positioning scan methods. The system may include first and second X-ray tubes that automatically return to predetermined initial positions before positioning scans: the first tube positioned directly above or below the gantry, and the second tube positioned at a lateral location on the gantry. The positioning scan method receives positioning scan instructions and executes operations based on instruction type. For front image scan instructions, the first tube may perform exposure and obtain front projection data. For lateral image scan instructions, the second tube may perform exposure and obtain lateral projection data. For dual-positioning image scan instructions, both tubes may perform exposure, obtaining both front and lateral projection data concurrently. This improves operational efficiency by eliminating tube repositioning delays and enabling simultaneous dual-plane imaging, thereby reducing overall scan time and enhancing workflow.
