Detailed description of the invention
In order to make technical scheme of the present invention and advantage clearly understand, below in conjunction with drawings and the embodiments, the present invention is further elaborated.Should be appreciated that detailed description of the invention described herein only in order to illustrative explanation the present invention, the protection domain be not intended to limit the present invention.
Succinct and directly perceived in order to what describe, hereafter by description some representational embodiments, the solution of the present invention is set forth.Details a large amount of in embodiment only understands the solution of the present invention for helping.But these details can be not limited to when clearly, technical scheme of the present invention realizes.In order to avoid unnecessarily fuzzy the solution of the present invention, some embodiments do not describe meticulously, but only give framework.Hereinafter, " comprising " refers to " including but not limited to ", " according to ... " refer to " at least basis ..., but be not limited to only basis ... ".Due to the language convention of Chinese, when hereinafter not particularly pointing out the quantity of a composition, mean that this composition can be one also can be multiple, or can be regarded as at least one.
Fig. 1 is the projecting method flow chart according to embodiment of the present invention medical image.
As shown in Figure 1, the method comprises:
Step S101: the x-ray image and the visible images that obtain irradiated body.
Here, the details of the x-ray image obtaining irradiated body is first elaborated.
Can by testee (i.e. irradiated body) in advance cloth be seated between X source and X-ray detector (such as image intensifier, etc.).X source can comprise a control unit and an X-ray tube.The pulse signal that the control unit of X source sends is through being sent to the filament in X-ray tube after power amplification, excitation X-ray tube produces X-ray.X-ray through irradiated body, thus forms the x-ray image of irradiated body in X-ray detector.
Preferably, X source can adopt the wide conditioning technology of pulse, to ensure that X-ray tube electric current and tube voltage keep constant.X source preferably can also have Slow starting of high voltage function, to make X-ray tube anode without high voltage overshoot phenomenon.And the control unit of X source can adopt miniature patch device, and preferably with the work of 20KHz equifrequent, thus good stress release treatment, think that operator provide quiet environment for use.For guaranteeing safety, X source can also be added with polytype protector, and embodiment of the present invention does not repeat this.
X-ray detector can detect X-ray to form x-ray image, such as based on traditional optical methods such as photographic plates based on various ways.Preferably, X-ray detector can also form medical image based on various digitized X-ray Detection Techniques.Such as, X-ray detector can also be specifically image amplifier, charge-coupled image sensor (CCD) type detector, Flat digital radiophotography (DR) detector, CCD DR detector, linear array DR detector, etc.
