[Gate-users] The design of CylindricalPET system with Rsectors of different structures

[Susana Branco Silva]

Hi Jinxia,

 

As you can read in the User’s Guide (pag. 51):

 

cylindricalPET is defined as a cylinder in the world, with a non zero inner
radius

-       rsector (depth=1) is defined as a box, and repeated with a ring
repeater in cylindricalPET

-       module (depth=2) is a box inside rsector. It is repeated by a
cubicarray repeater with no X

repetition (repeatNumberX = 1). This level is optional.

-       submodule(depth=3) is a box inside module. It is repeated by a
cubicarray repeater with no X

repetition (repeatNumberX = 1). This level is optional.

-       crystal (depth=4) is a box inside submodule. It is repeated by a
cubicarray repeater with no X

repetition (repeatNumberX = 1)

-       layer (depth=5) is a (or several, in the case of the phoswich
system) radially arranged box(es)

inside crystal. Do not use a repeater for layers, but build them one by one
in your macro. layer

must be set as a sensible detector with the macro command: /attachCrystalSD.

 

You only can define one rsector level
 

What do you really want to define as your geometry?

 

Cheers,

Subject: [Gate-users] The design of CylindricalPET system with Rsectors of
different structures

 

Dear users:
     I want to design a cylindrical PET system with four Rsectors .In this
system,the Rsectors have
 different structures.The number of modules of theirs is not equal.I have
tried a few ways to do that ,
but all failed.Can someone tell me how to do that? 

Thank you very much!
Best wishes!
