Abstract
The study was a simulated experimental study using the CT imaging data of patients in DICOM format in a model Three students who learn to interventional ultrasound for less than 1 year and three experts who have more than 5 years of experience in ablation techniques in MWA performed the preoperative planning for 39 lesions mean diameter 375 ± 173 cm of 32 patients using twodimensional 2D image planning method and 3D VPTPS respectively The number of planning insertions planning ablation rate and damage rate to surrounding structures were compared between2D image planning group and 3D VPTPS groupThere were fewer planning insertions lower ablation rate and higher damage rate to surrounding structures in 2D image planning group than 3D VPTPS group for both students and experts When using the 2D ultrasound planning method students could carry out fewer planning insertions and had a lower ablation rate than the experts p 0001 However there was no significant difference in planning insertions the ablation rate and the incidence of damage to the surrounding structures between students and experts using 3D VPTPS
