cirs 062m电子密度模体
厂家：美国computerized imaging reference systems, incorporated (美国cirs)
在ct扫描过程，应对器官的不均匀性，非常需要了解一个在ct数量及电子密度之前的精确关系。cirs 062m电子束模体就是这样一种针对各种器官多样性和ct值之前协调的精密仪器。
062m是由多种塑料水的材料组成的碟片，包括头部及腹部。在扫描区域的17个不同定位，有8种不同的等效器官效用。
评估ct值
纠正不均匀性
建立ct数量与组织电子素 的关系

because ct scans are used to correct for tissue inhomogeneities in radiotherapy treatment planning, it is important to obtain a precise relationship between ct number (in housfield units)【敏感词】electron densities. the model 062m electron density phantom enables precise correlation of ct data to electron density of various tissues. the phantom is manufactured from cirs tissue equivalent materials.
the model 062m consists of nested disks made from plastic water®. this enables both head【敏感词】abdomen configurations. eight different tissue equivalent inserts can be positioned at 17 different locations within the scan field. included is a syringe insert that can be filled with any fluid【敏感词】solid material. special marker inserts enable quick assessment of the ct scanner’s distance measurement accuracy.
physicists performing treatment planning need accurate tools to evaluate ct scan data, correct for inhomogeneities【敏感词】to document the relationship between ct number【敏感词】tissue density. to improve the accuracy of your treatment planning, consider the cirs model 062 electron density phantom.
the 062m is just one of three configurations available as a part of the cone beam ct electron density & image quality phantom system.
•evaluate ct scan data
•correct for inhomogeneities
•document relationship between ct number【敏感词】tissue electron density
•simulate indicated tissue within the diagnostic energy range
•quick assessment of distance registration
