Abstract

The invention relates to a navigation view angle automatic adjustment method, which utilizes a reference tool, a tracking tool and a navigator. The navigator can recognize the reference tool and the tracking tool; the reference tool is fixed on an operated object; and image data are stored in a computer. The navigation view angle automatic adjustment method is characterized in that the tracking tool is fixed on the forehead of an operator and close to the eyes as close as possible; the navigator automatically tracks positions of the tracking tool on the operator forehead and the reference tool on the operated object; information transmitted by the navigator is subjected to computation processing by the computer, so that the view angle direction of the operated object image displayed on the computer and the practical observation view angle direction of the operator are consistent. During application process of the navigator, the view angle direction of the operated object image displayed on computer is consistent or approximate to the practical view angle direction of the operated object observed by the operator.

Description

Navigator views visual angle automatic regulating method

Technical field

The present invention relates to a kind of navigator views visual angle automatic regulating method; This method cooperates with navigator; Let show on the computer seen that with operator the real visual angle direction of operating thing is consistent or close by the view directions of the image of operation object; As be used in the surgical navigational process, let the view directions of the patient image that shows on the computer see that with the doctor patient's real visual angle direction is consistent as far as possible.

Technical background

Adjust the technology of picture display direction at present; Portable electric device like the whole picture direction of CN101131608A automatic regulator; Constitute by housing, display, pick off, microprocessor; The inclination angle that utilizes aspect sensor to detect the electronic installation picture changes, and makes microprocessor adjust picture display direction automatically again.

Current operational approach is an example with the surgical navigational:

1. reference tool (Reference) is fixed on one's body the patient, (Track Tool) is fixed on the operating theater instruments with trace tool;

2. in the operation process, navigator can be discerned Reference and TrackTool;

3. through computer, not only can demonstrate image before the patient's through CT scan the art, but also can be with real-time before patient's art, the showing in the image of operating theater instruments and patient's relative position.

The deficiency of current techniques mainly contains following several respects:

Though can be with real-time before patient's art, the showing in the image of operating theater instruments and patient's relative position, the visual angle of image or be changeless, or need operator to come to adjust on computers dynamically; It is inconsistent that thereby the visual angle and the computer that cause the patient that the doctor saw under a lot of situation are attend institute images displayed visual angle.For this reason, how solving the doctor visual angle consistent with computer images displayed visual angle is a difficult problem.

Summary of the invention

The object of the invention is to provide a kind of navigator views visual angle automatic regulating method, and in the process of using navigator, what show on the computer is seen that with operator the real visual angle direction of operation thing is consistent or close by the view directions of the image of operation object.

The object of the invention realizes through following technical proposals: a kind of navigator views visual angle automatic regulating method; Utilize reference tool (Reference), trace tool (Track Tool) and navigator; Navigator can be discerned Reference and Track Tool; Reference is fixed on by on the operation object, and image data is stored in the computer, it is characterized in that: the forehead place that Track Tool is fixed on the operator; As far as possible near eyes; The Track Tool of the automatic tracking operation person's head of navigator and by the position of the Refrence of operation on the object, the information transmitted of navigator is through the computing of computer, lets show on the computer consistent with the real visual angle direction of operator's observation by the view directions of operation subject image.

On the such scheme basis, described Track Tool is fixed on the forehead place through operator's medicated cap.

On the such scheme basis, obtaining image data with CT scan is initial data; Refrence is fixed on by on the operation object, Track Tool is placed on operator's the forehead medicated cap; Start navigator, the Track Tool on tracking operation person's medicated cap and by the position of the Refrence on the operation thing automatically through the computing of computer, lets on the computer view directions of images displayed consistent or approaching with operator's real visual angle direction.

The present invention provides the purposes of a kind of navigator views visual angle automatic regulating method, is used for surgical navigational.

Advantage of the present invention and good effect: in using the process of navigator, can let show on the computer consistent or close with the real visual angle direction of the operation thing of operator's observation by the view directions of the image of operation object.

The specific embodiment

Navigator views visual angle automatic regulating method; Utilize reference tool (Reference), trace tool (Track Tool) and navigator; Navigator can be discerned Reference and Track Tool; Reference be fixed on by the operation object on, with CT scan obtain image data be original data storage in computer, wherein: the forehead place that Track Tool is fixed on the operator; As far as possible near eyes; The Track Tool of the automatic tracking operation person's head of navigator and by the position of the Refrence of operation on the object, the navigator information transmitted is through the computing of computer, lets show on the computer consistent with the real visual angle direction of operator's observation by the view directions of operation subject image.

Application examples

With the surgical navigational is example:

Device is prepared: computer, navigator, Track Tool and Reference.

Track Tool is placed on doctor's the operating cap of head; Reference is contained in patient and treats surgical site; Navigator can be from the position of Track Tool on the operating cap of motion tracking doctor head and the Refrence on the patient; Through the computing of computer, let the view directions of the patient image that shows on the computer see that with the doctor patient's real visual angle direction is consistent as far as possible.

Operating process is following:

1. obtain image data before patient's the art with CT scan;

2. before the operation beginning, Refrence is fixed on one's body the patient, Track Tool is placed on doctor's the operating cap of head;

In the surgical navigational process; Navigator can be from the position of Track Tool on the operating cap of motion tracking doctor head and the Refrence on the patient; Through the computing of computer, let the view directions of the patient image that shows on the computer see that with the doctor patient's real visual angle direction is consistent as far as possible.

Claims

1. navigator views visual angle automatic regulating method; Utilize reference tool, trace tool and navigator, navigator can be discerned reference tool and trace tool, and reference tool is fixed on by on the operation object; Image data is stored in the computer; It is characterized in that: trace tool is fixed on operator's forehead place, as far as possible near eyes, the trace tool of the automatic tracking operation person's head of navigator and by the position of the reference tool on the operation object; The information transmitted of navigator is through the computing of computer, lets show on the computer consistent with the real visual angle direction of operator's observation by the view directions of operation subject image.
