活检装置
摘要：
提供一种活检装置，能容易使断层合成坐标系与活检坐标系对应，并能够根据基于断层合成图像指定的目标的指定位置，高精度地进行穿刺。确定基于断层合成图像指定的目标的位置作为第1指定位置。从在断层合成坐标系校正的两个校正立体灯泡位置向放射线检测器假想地投影第1指定位置，求出两个投影位置。根据立体灯泡位置和投影位置，将第1指定位置转换为所述立体坐标系中的第2指定位置。根据第2指定位置使活检针进行检查对象的穿刺。活检针基于在与立体坐标系之间进行了校正的活检坐标系而被驱动。
摘要（英）：

A position of a target designated based on a tomosynthesis image is identified as a first designated position. The first designated position is virtually projected to a radiation detector from two calibrated-stereotactic tube positions which have been calibrated into a tomosynthesis coordinate system so as to obtain two projection positions. The first designated position is converted into a second designated position in a stereotactic coordinate system based on stereotactic tube positions and the projection positions. A biopsy needle is inserted into a subject to be examined based on the second designated position. The biopsy needle is driven based on a biopsy coordinate system calibrated with respect to the stereotactic coordinate system.
