Title:
医用撮像システムのテーブルとC字アームの相対的位置に関する較正手順
Document Type and Number:
Japanese Patent JP5121860
Kind Code:
B2
Abstract:
A method of calibrating a mechanical model of behavior and movement of an interventional radiology table by moving the table over at least one degree of freedom, acquiring at least one set of images corresponding to different positions of the table and C-arm, obtaining at least one set of images of a test object from different positions, using the images of the test object to determine parameters of the mechanical model of table behavior and movement, and combining these parameters with data given by table movement sensors so as to deduce the true relative positions of the table with respect to the medical imaging system.
