The specific embodiment
This utility model provides a kind of PET/CT common frame that can effectively avoid existing different frame PET/CT machine to scan the fusion image registration error of bringing at diverse location to the above deficiency of prior art.Be described further below in conjunction with accompanying drawing and specific embodiment technical scheme this utility model:
A kind of PET/CT common frame of this utility model comprises:
Shell 1;
Frame 12 is arranged on shell 1 inside;
Said swivel plate 11 is provided with: PET detector 4 is used to form the positron emission computed tomography images;
Said PET detector (4) and CT detector (5) are configured on the roughly same circumference, and the phase non-overlapping copies; PET detector (4) and the detected image of CT detector (5) overlap basically, and the fusion image positional precision reaches in the 0.2mm.
A kind of PET/CT common frame of this utility model also comprises examinating couch 6; Said examinating couch 6 is arranged on the bedstead 9; Described bedstead 9 and frame 12 vertical placements, and be arranged on the same centrage with shell 1, examinating couch 6 can move on bedstead 9; And acceptor was lain low in 6 last times of examinating couch, be positioned on the same horizontal plane with rotating shaft 10.Make the scanning cross facet of PET detector 4 and CT detector 5 be arranged in the body part of acceptor, thereby confirm the acceptor lesions position.
Further, also be provided with head positioning pillow 8 on the said examinating couch 6, be used to hold up and locate the head of acceptor, the height of said head positioning pillow 8 is for making the acceptor head coaxial with rotating shaft 10.Make the scanning cross facet of PET detector 4 and CT detector 5 pass the head of acceptor, thereby confirm acceptor head lesions position.
A kind of PET/CT common frame of this utility model also has a lower component and characteristics simultaneously:
Said shell is provided with machine hole 13, and examinating couch 6 can go deep into machine hole 13 makes acceptor accept the scanning imagery of PET detector 4 and CT detector 5, and the hole depth in said machine hole 13 is between 0.6～1m.Said bedstead 9 the use a computer height and the translation of telecontrol engineering control examinating couch 6.PET/CT machine hole depth of the prior art is generally 1.6m; Its full environment that surrounds is easy to make acceptor to feel oppressive; Even fear arranged; The PET/CT common frame is arranged on PET detector 4 and CT detector 5 on the same frame, and hole depth is reduced about one times, has reduced patient's fear of confined spaces sense effectively.
The shell 1 of said scanning device, inside also are provided with panel 2 and display module 3, and panel 2 all links to each other with computer with display module 3, is convenient to controling of said PET/CT common frame.Described panel 2 comprises PET panel and CT panel.PET panel and CT panel are arranged on the frame 12, and lay respectively at the both sides in machine hole 13.Said PET panel is connected same computer workstation and display module 3 respectively with the CT panel; The scanning imagery of said PET detector 4 and CT detector 5 carries out image co-registration by computer; Accomplish PET and CT control and image co-registration through same computer workstation, to use the clinical needs of multiple complicacy.
Examinating couch 6 in this utility model is to carry the parts of putting acceptor.Carrying when putting acceptor, be configured in the head that connects acceptor and the direction of foot on the length direction of examinating couch 6, be configured in the direction about the connection acceptor on the width of examinating couch 6.Examinating couch 6 when moving up entering machine hole 13, from bedstead 9 away from, so below do not have fulcrum, some deflections can take place.
On the medial surface of the tubular of swivel plate 11, dispose PET detector 4, X ray emitter 15, and with X ray emitter 15 paired CT detectors 5.Swivel plate 11 with the rotating shaft 10 that is in the position parallel with the length direction of examinating couch 6 be the center (said rotating shaft 10 be with place top board on the axle that roughly overlaps of the axon of acceptor) be rotated.When the X ray CT image taking and during the PET image taking, swivel plate 11 is rotated.In this embodiment, revolved in per 0.5 second and to turn around.At this; In this enforcement formula; To carry out the shooting of PET image,, this rotary speed is not limited especially as long as this rotation can detect gamma ray on 360 degree complete cycle directions when the shooting of PET image with the same rotary speed of shooting of common X ray CT image.
