Fristrup, T. Pless, J. Durup, M. Mortensen, H. Nielsen, C. Hovendal] Background: Laparoscopic ultrasound is an important modality in the staging of gastrointestinal tumors. Correct staging depends on good spatial understanding of the regional tumor infiltration. Three-dimensional (3D) models may facilitate the evaluation of tumor infiltration. The aim of the study was to perform a volumetric test and a clinical feasibility test of a new 3D method using standard laparoscopic ultrasound equipment. Methods: Three-dimensional models were reconstructed from a series of two-dimensional ultrasound images using either electromagnetic tracking or a new 3D method. The volumetric accuracy of the new method was tested ex vivo, and the clinical feasibility was tested on a small series of patients. Results: Both electromagnetic tracked reconstructions and the new 3D method gave good volumetric information with no significant difference. Clinical use of the new 3D method showed accurate models comparable to findings at surgery and pathology. Conclusions: The use of the new 3D method is technically feasible, and its volumetrically, accurate compared to 3D with electromagnetic tracking.
