该命令用于将选定的 ROI 工具排列在一条直线上。该直线通过第一个选定的 ROI 工具的几何中心线定义。所有其他选定的 ROI 工具都会垂直于直线移动，使其几何中心在直线上。
•操作步骤
•选择 ROI 绘图工具，所有 ROI 工具都应位于该工具的几何中心线上。
•按住 "Ctrl "键的同时选择所有其他 ROI 工具。这些工具将被移动。
•在下拉菜单
中选择要放置在几何中心线上的符号
。
ROI 工具的几何中心线
几何中心线是指通过 ROI 工具几何中心的直线，该直线垂直于从 ROI 几何中心到 ROI 工具旋转手柄的连线。
This command can be used to arrange selected ROI tools on a straight line. The straight line is defined via the geometric center line of the first selected ROI tool. All other selected ROI tools are moved perpendicular to the straight line so that their geometric center ends up on the straight line.
•Procedure
•Select the ROI drawing tool on whose geometric center line all ROI tools should be located.
•Select all other ROI tools while holding down the "Ctrl" key. These will be moved.
•Select symbol for placement on the geometric center line in drop-down command menu .
Geometric center line of an ROI tool
The geometric center line refers to the straight line that passes through the geometric center of the ROI tool and is perpendicular to the connecting line from the ROI geometric center to the rotary handle of the ROI tool.
