Computer with graphical user interface (calculates CT bed coordinates of the tumor)

Abstract

1. The name of the design product: computer with graphical user interface (CT bed coordinates of the center of the tumor are calculated). 2. The use of the design product: graphical user interface in the screen. 3. The design features of the design product: graphical user interface in the screen. 4. The picture or photo that best shows the design features: front view. 5. The use of the graphical user interface: accurately finding the center of a solid tumor under CT and the corresponding body surface marker point, directly used for radiotherapy planning and radiotherapy, reducing dosimetric errors. 6. The human-computer interaction mode of the graphical user interface: when positioning a tumor radiotherapy patient under CT, place three metal marker points at the intersection of the cross lines projected by the external laser system on the patient's body, and record the coordinates of the CT bed at this state. In the CT transverse image layer, determine the center coordinates formed by the three metal marker points, and select the appropriate solid tumor center coordinates by the radiotherapy physician. Input the coordinates of the two points into the Marker coordinates and the tumor center ISO coordinates in the left half of the interface in the front view, and click to calculate the difference. The distance and relative direction of the reference point and the tumor center in three dimensions can be calculated. Click on the value transfer to transfer the specific numerical value of the calculation to the bed hardware calculation module in the right half of the front view. Click on the calculation again to calculate the CT bed coordinates of the tumor center under the external laser system. Move the CT bed and the external laser positioning system to the calculated coordinates. At this time, the cross intersection projected by the laser positioning system on the body is placed with three metal marker points. The subsequent plan design and radiotherapy use the tumor center and the corresponding body surface marker point of the tumor center.
