Accuracy, but since CT/MRI image scanning parameter is inconsistent, the repeatability of patient posture is difficult to grasp, and scans acquisition
Image is often difficult to find consistent position, this brings very big difficulty and uncertainty to subsequent image registration and fusion.
Approximation position characteristic point is mostly used to be registrated greatly currently based on the Study of Registration of characteristic point, and the image of approximate registration is for melting
It closes, result will have a greatly reduced quality in clinical application value.Previous research in, nearly all using anatomical structure mark point as
Reference marker point carry out position determination and fusion accuracy analysis, the registration of image is inaccurate, fusion and evaluation procedure compared with
To be many and diverse, to limit blending image in clinical practical application.Labeled in vitro point subplan can relatively efficiently solve
CT/MRI image volume bit integrity problem, handmarking's point can image on CT/MRI image.In same tag point location item
MRI T1WI enhancing sequence and CT positioning scanning are carried out under part, are obtained MRI image and CT image, are then looked for according to external markers
To the image of the same level of CT/MRI, rapid registering and fusion are carried out.But it this rely solely on limited labeled in vitro point and deposits
In fatal weakness, that is, be difficult to realize and be shown to a certain handmarking's point on CT/MRI image, position consistency there are still
It is uncertain.And be equipped with plastics positioning plate using foundation ring and positioned, it can be preferably imaged in CT image scanning, but
Since the position line of foundation ring and plastics positioning plate is all metal when MRI image scans, then artifact is larger, and positioning image can not make
With.

The embodiment of the invention provides a kind of positioning marked ruler for head positioning in radiation therapy, radiation therapy head positioning
It include: telltale mark bar 1 with telltale mark ruler, the telltale mark bar 1 is that inside sets the horizontal straight-bar of cavity, in the cavity
Filled with filler；The telltale mark bar 1 is symmetrically arranged with annular groove 2, and 1 surface of telltale mark bar by two close end surface
It is circumferentially uniformly provided with the fixing groove 3 extended along its length, each fixing groove 3 is connected to two annular grooves 2, and described each
Fixing groove 3 is perpendicular with described two annular grooves 2.
In the above-described embodiments, telltale mark ruler position accurate positioning proposed by the present invention, improves CT/MRI image and matches
