Background technology
Spinal surgery, Pain Management are section office with fastest developing speed nearly ten years.The development of technology, living-pattern preservation, respectively
Plant patient's explosive growth of pain, and increasingly rejuvenation.The neck-shoulder pain, lumbago and leg pain of human body, includes the pain of hand, arm, pin,
The reason for considerable part, is related to the backbone of human body, interverbebral disc and bone, joint.The development of modern clinic, skeletal structure form
And the research and application of biomethanics are just turning into the key and focus of clinic, three-dimensional imaging and 3D printing technique are to clinical skill
Art brings gratifying change.
It is used as the Main Means of current image check：Nuclear magnetic resonance, CT, be substantially patient lying, the inspection of clinostatism, no
When can truly reflect standing spinal biomechanicses change, and in lumbar vertebrae stretching process intra-and extraspinal structure change.Only
DR can bring certain obstacle to clinical diagnosis in erect position into bidimensional image.Meanwhile, the precision of images of current CT axial directions
It is not high, it is impossible to obtain high-quality 3-dimensional image.Caused for current backbone, joint, the clinical diagnosis of bone and research and development
Certain influence and limitation.
The appearance of the orthostatic position magnetic resonance (G-SCAN) of Bai Sheng company, represent magnetic resonance examination position from prostration to
Upright development, develops from global function to tailored version direction.In orthostatic position due to the dynamic change of soft tissue structure, it can often find
The problem of conventional dorsal position is hidden.The clinical practice for G-SCAN has widely been approved abroad at present, and takes
Obtained certain achievement.But G-SCAN scannings still have many weak points, because the open type magnetic resonance of orthostatic position is swept
Retouch that instrument field strength is relatively low, picture quality is poor compared with high-field magnetic resonance, and sweep time is long, and patient is difficult in the posture of orthostatic position
Maintain；Morphologic features are also only rested on for the orthostatic position lumbar vertebrae MRI researchs checked.Also need to further improve and hair
Exhibition.
Current conical beam CT (CBCT) be mainly used in image trace in oral cavity head imaging and tumour radiotherapy with
Positioning.Oral cavity head imaging and application are very ripe.Its main feature：1st, radiate low；2nd, image clearly, can be obtained
Space 0.1mm resolution ratio, 0.3 to 0.5 axial resolution much larger than CT can obtain high-quality 3-dimensional bone image；3、
Price is low, far below CT, nuclear magnetic resonance.Current large-sized dynamic imaging plate technique is highly developed, be full body into
As having established good basis.
