The specific embodiment
In prior art, carrying out before digital medical image photography, set in advance photographic parameter according to the clinical object of difference, will cause the image of obtaining after photography can only meet the demand of single clinical object.
After deliberation, inventor finds, obtaining before original figure medical image, photographic parameter is not done to selection and the adjustment for clinical object, and only obtaining after original figure medical image, according to different clinical objects, described original figure medical treatment figure is processed again, can be obtained the multiple image that meets different clinical objects.
For the problems referred to above, embodiments of the invention provide a kind of digital medical image processing method.Fig. 1 is the flow chart of described digital medical image processing method.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Set forth in the following description a lot of details so that fully understand the present invention, implemented but the present invention can also adopt other to be different from alternate manner described here, therefore the present invention is not subject to the restriction of following public specific embodiment.
First, please refer to Fig. 1, execution step S101, obtains pending digital medical image.In one embodiment of this invention, described digital medical image is the X-ray image that digital radiography (DigitalRadiography, DR) equipment obtains.In other embodiments of the invention, described digital medical image can be also the medical image beyond X-ray image, as by computed tomography (computer tomography, CT) image that equipment or nuclear magnetic resonance (Magnetic Resonanceimaging, MRI) equipment obtains.
In other embodiments of the present invention, described pending digital medical image can be the digital medical image about human body, can be also zoologic digital medical image.
Then,, please continue to refer to Fig. 1, execution step S102, obtains clinical object information.In an embodiment of the present invention, described clinical object information comprises wish diagnosis organ information and/or picture display mode.
For example, in one embodiment of this invention, doctor need to diagnose certain patient's shank bone condition, diagnose this clinical object based on shank skeleton so, described clinical object packets of information is containing the diagnostic region scope of shank, and the display mode of the digital medical image of shank (mode of highlights bone).
Then,, please continue to refer to Fig. 1, execution step S103, chooses the image processing algorithm corresponding with described clinical object based on described clinical object information.
In an embodiment of the present invention, described image processing algorithm comprises: organic image extraction algorithm, image display algorithm and image sharpening algorithm.
For example, in one embodiment of this invention, doctor thinks and causes that the reason of certain patient's chest pain may be for heart disease, but a large amount of organs are comprised in the original figure medical image due to chest, so can be according to the clinical object of heart disease diagnosis, select cardiac image extraction algorithm as described image processing algorithm, cardiac image is extracted from the original figure medical image of described chest.
Again for example, in another embodiment of the present invention, doctor thinks and causes that the reason of certain patient's skelalgia may be for muscle injury, so can be according to the clinical object of muscle injury diagnosis, the image display algorithm that selection highlights muscle is described image processing algorithm, by the muscle image of shank from the original figure medical image saliency of described shank out.
It should be noted that, described image processing algorithm can comprise a kind of algorithm, can be also the combination of many algorithms.For example, in the time that the clinical object based on lung diagnosis is photographed inspection, can select organic image extraction algorithm and image sharpening algorithm simultaneously.
Then,, please continue to refer to Fig. 1, execution step S104, utilizes the image processing algorithm of described correspondence to process described pending digital medical image, to generate the image that meets described clinical object.
For example, in one embodiment of this invention, for the clinical object of heart disease diagnosis, utilize cardiac image extraction algorithm from the digital medical image about chest, to extract the image of heart, for doctor, patient's heart is diagnosed.
Again for example, in another embodiment of the present invention, for the clinical object of muscle injury diagnosis, utilize and highlight the image display algorithm of muscle from the image of the digital medical image saliency muscle about shank, for doctor, patient's muscle situation is diagnosed.
It should be noted that, in an embodiment of the present invention, can adopt many algorithms to carry out parallel processing to described pending digital medical image, for example, in the time that described pending digital medical image is chest image, can, in adopting thoracic vertebra skeleton image to highlight algorithm thoracic vertebra is come from described chest image saliency, select cardiac image extraction algorithm that cardiac image is extracted from described chest image, above-mentioned two image processing process walk abreast.
That is to say, in the time that doctor exists about the multiple suspection of the cause of disease, hypothesis that can be based on different, select the position for the treatment of diagnosis based on the polyalgorithm of the clinical object of difference to carry out parallel diagnosis simultaneously, therefore, prior art relatively, this will shorten doctor's searching the time the cause of disease.
As shown in Figure 2, in an embodiment of the present invention, utilize the image processing algorithm of described correspondence to process described pending digital medical image, comprise with the method that generates the image that meets described clinical object: step S104a, step S104b, and step S104c.
