Abstract
The invention provides a PET/CT image fusion and combination diagnosis all-in-one machine which comprises fixed racks, a PET device arranged on the first fixed rack, a CT device arranged on the second fixed rack, and an image workstation which is used for conducting fusion processing on PET images detected by the PET device and CT images detected by the CT device, and the image workstation is respectively connected with the PET device and the CT device. By means of the dynamic integration of PET and CT, the PET images detected by the PET device and the CT images detected by the CT device are fused, pathology and physiology changes and morphological structures of lesions are reflected simultaneously, and accuracy of diagnostic results is effectively improved.
Description
Technical field
The present invention relates to a kind of instrument of radiodiagnosis, relate in particular to a kind of PET(positron emission computerized tomography)/CT(electronic computer x-ray tomography) image fusion joint diagnosis all-in-one.
Background technology
PET is that the medicines such as the part of the glucose that utilizes the positron emission body tag, aminoacid, choline, thymus pyrimidine, receptor and blood flow display agent are tracer, in the anatomic image mode, show metabolism, function, blood flow, cell proliferation or the receptor distribution situation of body and lesion tissue cell from molecular level, be the clinical diagnostic message that more physiology and pathology aspect are provided.The magnetic resonance imaging,MRI instrument utilizes the characteristics of nuclear spin campaign, in externally-applied magnetic field, after radio-frequency pulse activates, produces signal, with detector, detects and input computer, through processing conversion displayed map picture on screen.CT is different to the absorption of x-ray and transmitance according to the human body different tissues, the high instrument of application sensitivity is measured human body, then will measure obtained data input electronic computer, after electronic computer is processed data, just can photograph section or three-dimensional image that human body is examined position, find the tiny pathological changes at any position in body.
At present, the medical institutions of China generally adopt independently PET and CT, when needs obtain PET/CT image fusion joint diagnosis as a result the time, needing first to carry out respectively PET detection and CT detects, then PET detected image and CT detected image are carried out to fusion treatment, yet existing detection mode is comparatively loaded down with trivial details, also affected the accuracy of diagnostic result.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of PET/CT image fusion joint diagnosis all-in-one, by PET and CT are organically combined, PET detected image and CT detected image are merged, pathophysiological change and the morphosis that can reflect focus effectively improve the accuracy of diagnostic result simultaneously.
In order to achieve the above object, the invention provides a kind of PET/CT image fusion joint diagnosis all-in-one, comprising:
PET equipment, be arranged on the first fixed frame;
CT equipment, be arranged on the second fixed frame;
Image workstation, the CT image obtained for PET image that described PET equipment Inspection is obtained and described CT equipment Inspection carries out fusion treatment, respectively with described PET equipment and described CT equipment connection.
Preferably, described CT equipment is arranged on the place ahead of described PET equipment.
Preferably, the radially effective field of view of described PET equipment and the radially effective field of view of described CT equipment are concentric, the least common multiple of the minimum bed thickness that is spaced apart described CT equipment of described PET equipment and described CT equipment.
Preferably, described CT equipment by the cushion setting on the ground.
Preferably, described CT equipment passes described cushion connection ground by foundation bolt.
