Marker Pen

Description

Fiducial markers are tiny metal objects (about the size of a grain of rice). They help your healthcare providers line up the beams of radiation and make sure your radiation therapy is delivered exactly the same way each time. This helps them target the tumor and avoid your nearby healthy tissue.

 

基准标记是微小的金属物体（大约一粒米的大小）。它们可以帮助您的患者排列放射束，并确保您的放射治疗每次都以完全相同的方式进行。这有助于他们靶向肿瘤并避开您附近的健康组织。
