cirs 062m電子密度模體

 廠家：美國computerized imaging reference systems, incorporated (美國cirs)

在ct掃描過程，應(yīng)對器官的不均勻性，非常需要了解一個在ct數(shù)量及電子密度之前的精確關(guān)系。cirs 062m電子束模體就是這樣一種針對各種器官多樣性和ct值之前協(xié)調(diào)的精密儀器。

062m是由多種塑料水的材料組成的碟片，包括頭部及腹部。在掃描區(qū)域的17個不同定位，有8種不同的等效器官效用。

組織內(nèi)的診斷能量范圍

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)【敏感詞】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【敏感詞】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【敏感詞】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【敏感詞】to document the relationship between ct number【敏感詞】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【敏感詞】tissue electron density

•simulate indicated tissue within the diagnostic energy range

•quick assessment of distance registration

* physical density - the actual physical density of the insert can vary within ± 1％ of the manufacturing target density.
note: cirs strongly recommends that the user inputs the electron density whenever prompted for material data by the tps.
