Problems solved by technology

However, as mentioned above, all the above methods can only achieve positioning along the longitudinal direction, and the operator still needs a pre-positioning imaging sequence to obtain a pre-positioning image for determining the final target imaging position

no. 1 approach

[0046] figure 1 A schematic diagram of an image forming apparatus to which the first embodiment of the present invention is applied is shown. figure 1 In , a magnetic resonance (MR) imaging device is taken as an example for illustration. The imaging device includes, for example: an examination table 2 on which the subject 1 is placed; a distance positioning device for positioning the detected part 3 of the subject 1; Region of the imaging device (magnet) 4 . In this embodiment, the subject 1 lies on the examination bed 2, and the distance between the detected part 3 of the subject 1 and the imaging device 4 is determined by the distance positioning device, and then the examination bed 2 transports the subject 1 into the imaging device 4, and align the detected part 3 with the imaging area of ​​the imaging device 4 according to the position determined by the distance positioning device, and make the imaging device 4 image the detected part 3.

no. 2 approach

[0061] In daily diagnostic health checks, in the imaging of the imaging device, not only images in the vertical direction are provided, but sometimes they are rotated or flipped at a certain angle for easier diagnosis. In this case, on the basis of the above-mentioned first embodiment, this embodiment also provides an angle positioning device capable of detecting the rotation and flip angles of the indicator 5 in space. Refer to the attached Figure 7 , the configuration and angle detection of the angle positioning device according to this embodiment will be described. Figure 7 A structural diagram of the angle positioning device is shown. The angle positioning device has the same structure as the first embodiment except that the structure of the indicator 5 is different from the first embodiment.

[0062] Such as Figure 7 As shown, in the indicator 5 of this embodiment, in addition to the signal generator 9 , an auxiliary signal generator 13 is also provided on the side ...

no. 3 approach

[0070] In the above-mentioned first and second embodiments, it was exemplified that three signal detectors 6, 7, 8 are provided in the imaging device, and one signal generator 9 is provided in the detected part of the subject, but it is not limited to Here, for example, in the case of a plurality of detected parts, different from the above-mentioned embodiment, a plurality of, for example, three signal generators 9 may be provided, and the three signal generators 9 may be arranged in a predetermined positional relationship. In the imaging device, a plurality of signal detectors corresponding to the number of the plurality of detected parts are provided on the detected parts. For example, three signal generators arranged on the imaging device sequentially send out ultrasonic signals, which are received by multiple signal detectors, so as to determine the positions of the multiple signal detectors relative to the signal generators, and then determine multiple detected signals.

Abstract

The invention provides an imaging device and positioning device characterized by comprising the following structures: an imaging device used for imaging a detected portion of a detected body; a distance positioning device at least comprising two positioning signal devices (a signal generator and a signal detector), wherein one positioning signal device is arranged on the detected portion, the other positioning signal device is arranged in a position having a preset position relation with the imaging device. The distance between the two positioning signal devices is detected so as to obtain the position of the detected portion, relative to the imaging device, at least in one direction in the three dimensional space. The imaging device and positioning device can mitigate preposition imaging sequence workload, and can prevent radiation risk on the detected body.

Description

technical field [0001] The invention relates to an imaging device and a positioning device. Background technique [0002] In current health and disease screening, magnetic resonance (MR) imaging or computerized tomography (CT) imaging is increasingly used. During such imaging scans with larger devices, the subject typically needs to lie down and be positioned in the area of ​​interest. The positioning target is the intended scan center at the time of imaging. Currently, localization methods are always implemented by laser markers or a series of position detection sensors along the longitudinal direction. [0003] This positioning method can only determine a transverse section on the subject's body by delineating a certain length along the longitudinal direction. But MR imaging or CT imaging always requires a clear target of a certain organ or region of the body. For this, not only the positioning of the transverse section is required, but also the positioning of the sagi...
