Protrusion part can be some false boss that support cylinder 20 generates in manufacturing process (pre-buried, inlay).It is kept away by design
It allows slot 230, the protrusion part on support 20 lateral wall of cylinder can be avoided, so that pet detector module 10 can
It is close to support cylinder 20 to install, saves installation space.
Referring to Fig. 3, in one embodiment, PET-MR equipment 01 further includes magnet coil 40, and magnet coil 40 is equipped with edge
The axially extending accepting hole 410 of magnet coil 40, support cylinder 20 are installed in accepting hole 410.Pet detector module 10 is installed
In on the side wall opposite with magnet coil 40 of support cylinder 20, mounting base 200 is far from the surface and magnet wire for supporting cylinder 20
There is gap between circle 40.Magnet coil 40 is formed by MR magnet and MR gradient coil, and MR gradient coil is located at MR magnet
Inside.Pet detector module 10 is installed on the side wall opposite with magnet coil 40 of support cylinder 20, i.e. pet detector mould
Block 10 is located in the interval between support cylinder 20 and MR gradient coil.And pet detector module 10 and support cylinder 20 are installed
After the completion, there is gap, which is naturally larger than detecting module main body 100 and magnet between mounting base 200 and magnet coil 40
Gap between coil 40.When the disengaging accepting hole 410 of pet detector module 10 in the carrying of support cylinder 20 thereon
It waits, 100 part of detecting module main body will not be bumped to, and enable 10 normal use of pet detector module, be hardly damaged.
In one embodiment, the quantity of pet detector module 10 can be at least two.At least two pet detectors
Module 10 forms detector rings on the lateral wall of support cylinder 20 along the circumferential array of support cylinder 20.When pet detector mould
When the quantity of block 10 is multiple, multiple pet detector modules 10 can arrange in a ring forms a detector rings.Alternatively, working as
When the quantity of pet detector module 10 is enough, multiple pet detector modules 10 constitute two even more than two detections
Device ring, the multiple detector rings of two or more are the axial alignments along support cylinder 20.The both ends of each detector rings are
The ring (assuming that referred to as outer ring) that the mounting base 200 of corresponding each pet detector module 10 is spliced, each pet detector ring
Middle section be corresponding each pet detector module 10 detecting module main body 100 be spliced ring (assuming that be known as in
Ring), then there is outer ring outer diameter to be greater than outside diameter of inner ring.Thus the pet detector module 10 of any position on 20 circumference of cylinder is supported
100 part of detecting module main body will not collide with 010 inner hole of magnet coil.So as to which pet detector mould is effectively ensured
The normal use and detector precision of block 10.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
