Doctor can use Medical Devices to scan patient, obtains the scan image for diagnosing conditions of patients, such as CT image or PET image, and doctor can see this scan image in the workstation software be connected with Medical Devices.Fig. 1 illustrates a kind of image by seeing in the display interface of workstation software, disclosure embodiment below, for the store method of this image description to image, but will be not limited to this image in concrete enforcement, other types image also can use method of the present disclosure.
Before description image storage method of the present disclosure, the several concepts first related in composition graphs 1 pair of the method are described:
Image: " image " in " image storage method " that the disclosure will describe, refers to the entirety shown in Fig. 1, in this entirety, had both comprised the head tissue 11 of patient, also comprised other regions 12 in image, and these other regions 12 are generally black region; Image is also included in some additional informations labeled in head tissue 11 or other regions 12, the mark of such as doctor or directional information, and the screen namely shown on workstation software entirety is the image that will preserve, and this is the principle following What You See Is What You Get.
Territory, effective display area: in above-mentioned image, territory, effective display area can comprise head tissue 11, to the image display area at the medical diagnosis on disease of patient helpful patient body scanning position, for above-mentioned territory, effective display area, and in other regions 12, there is no the body part of patient, be invalid viewing area.Fig. 1 illustrates territory, effective display area 13.
Additional marking information: on image; often can add the mark metrical information that some directional informations, four angle informations and doctor do; these information are referred to as additional marking information in the disclosure, such as, illustrate four angle information * * * * (can be patient's name) in FIG.
Image display control: the integral image shown in Fig. 1 shows control by image and shows, image display control can realize image display.Intuitively, the size of image display control, will directly have influence on the size of the frame shown in Fig. 1.Fig. 2 illustrates the effect of adjustment image display control, can see, after the size of adjustment image display control, area or the size in other regions 12 beyond patients head have also been obtained obvious change.
External system: such as, diagnosis report list or film etc., can be called external system, the image of Fig. 1 that doctor can will see on workstation software, is sent to external system and prints.
The image display control of external system: same, image to be shown in external system and also will show control by image, in the report that image can be shown by control, such as, at the image obtained the overall screenshotss of Fig. 1 according to the mode of What You See Is What You Get, be presented in report by control after being sent to report.
Can also be seen by above-mentioned Fig. 1 or Fig. 2, other regions 12 beyond patients head region, occupy larger area, this region is for the nugatory invalid viewing area of medical diagnosis on disease in fact, and, after the diagnosis report image shown in Fig. 1 being sent to external system, display control in report also needs to show this invalid viewing area, and the size of the image display control of diagnosis report is normally fixed, namely be fixing for showing the region of image, after above-mentioned invalid viewing area occupies larger area, the territory, effective display area with diagnostic value shows area on the contrary and reduces, may be not fogging clear, be unfavorable for the diagnostic work of doctor.The image storage method that the disclosure provides, for when preserving image secondary when report (such as, send to) reduce the invalid viewing area in image.
Image storage method of the present disclosure, flow process that can be shown in Figure 3:
In step 301, the territory, effective display area in computed image.
Such as, the territory, effective display area in image can be the region 13 of example in Fig. 1, includes the head scanning position of patient.In this step, by calculating the size in this territory, effective display area, such as, for the territory, effective display area 13 in Fig. 1, the length in this region, width can be calculated, the distance etc. of this region distance image border.
In step 302, by being used for the image display control showing image, being adjusted to and mating with territory, effective display area.
Such as, in this step, object reduces the scope in other regions 12, by adjustment image display control, the area of integral image can be changed, on the basis that territory, effective display area is constant, reducing of integral image area, will make in image containing the least possible region 12.Exemplary, can see Fig. 4, after to the image display control adjustment of image shown in Fig. 1, image only includes territory, effective display area substantially, is equivalent to reach the area of image utilize more effectively fully.
In step 303, the additional marking information of image is arranged in the picture, and preserves image.
Such as, shown in composition graphs 4, behind the region of adjustment image, be still attached in image by four angle informations, now again according to the principle of What You See Is What You Get, overall screenshotss obtain the image shown in Fig. 4.This image can be sent in diagnosis report and show.
By above-mentioned method, containing the least possible invalid viewing area in the image finally obtained, expand the ratio that territory, effective display area is shared in whole image, when the image shown in Fig. 4 is sent to diagnosis report, image display control in report shows this image, territory, effective display area will occupy the area of the overwhelming majority, and more clear, advantageously Yu doctor is to the diagnosis of image.
Fig. 5 illustrates another kind of image storage method, flow process shown in this Fig. 5, the more detailed enforcement describing image storage method, such as, describe and how image is shown control and be adjusted to and mate with territory, effective display area, and how add additional marking information etc. in image after the adjustment.Wherein, in the following description, identical with flow process shown in Fig. 3 step will no longer describe in detail.
In step 501, the territory, effective display area in computed image.
In this step, the method calculating territory, effective display area can have multiple, such as, can by the comparison of color, such as, the background colour (i.e. the color of invalid viewing area) of image is generally black, and the scanning area of patient is generally white, relatively distinguishes territory, effective display area and invalid viewing area by color.Again such as, can also be according to the operation (scaling, translation etc.) of doctor to image, obtain the regulation coefficient of some images, and calculate the size in territory, effective display area.
In step 502, adjust image display control, with territory, effective display area, there is identical wide high proportion.
Such as, the adjusted size of image display control, the size of the integral image shown in Fig. 1 will be changed, this step can adjust control, make the size of image consistent with the wide high proportion in territory, effective display area, such as, the region being substantially adjusted to Image control is in the diagram consistent with the ratio of width to height in territory, effective display area.
In step 503, the center in territory, effective display area is moved to the center of image display control.
Such as, on the basis of mating with the ratio of width to height that image shows region corresponding to control (i.e. image-region) in adjustment territory, effective display area, can image be moved, the center in territory, effective display area be moved to the center of image display control.
In step 504, adjustment territory, effective display area and image show the overlapping margins of control.
By above-mentioned step 502 to 504, by being used for the image display control showing image, being adjusted to and mating with the territory, effective display area in image.But in concrete enforcement, be not limited to above-mentioned order, also can be other method of adjustment or adjustment order, mate as long as territory, effective display area and image can be made to show control, namely above-mentioned steps be in the display according to territory, effective display area adjustment image.
The effect of composition graphs 4 also can be seen, territory, effective display area is filled with the display window of image, substantially no longer leaves black surround, namely substantially eliminates the invalid viewing area of periphery.
In step 505, the additional marking information of image is arranged in the picture, and preserves image.
In this step, additional marking information can be the markup information etc. of directional information, four angle informations or doctor, and diminish even if image to be shown control adjustment, above-mentioned additional marking information can not abandon, these information to the diagnosis of doctor by helpful.Exemplary, the addition manner of the following two kinds additional marking information:
Such as, additional marking information can be added on the image that image shows control display, that is, after have adjusted image display control and showing effective viewing area, still by this control display additional marking information.Be consistent before the setting position of additional marking information and control adjust, such as, directional information is still labeled in the centre position at the edge up and down of image, and the position of doctor's markup information also remains unchanged relative to the position in territory, effective display area.These information are limited in image display window.
Again such as, by another image display control, image can be reloaded, and add additional marking information on the image reloaded.Such as, additional marking information can be used GSPS (GrayscaleSoftcopyPresentationState, gray scale soft copy expression status) store, or use the internal entity object of the software for performing this image storage method to store, after adjustment image display control mates with territory, effective display area, integral image is intercepted and reloads, then additional marking information is added to above new image.
In step 506, described image is sent to external system.
Such as, can the image that step 505 obtains be sent in film or diagnosis report, show this image by the image display control of external system.
In above-mentioned image storage method, as above, the adjustment of image display control will change the change in size of whole image-region, if the region of image display is window area in workstation software, the change being exactly so window area is shown caused by the adjustment of control by image.Window area is adjusted to and matches with the territory, effective display area in image by the disclosure, decreases invalid viewing area as much as possible.
In addition, when preserving image in step 505, image storage is the principle according to What You See Is What You Get, carries out screenshotss preservation to window area.And additional marking information can regard the information be attached on image as, exemplary, can the window area entirety of screenshotss be regarded as two-layer, image does one deck, additional marking information does one deck, and the adjustment of control display belongs to the adjustment to image layer, then adds on image after the adjustment by additional marking information, be equivalent to two-layer combination, the image be sent in report is also the image after combination.This mode had both eliminated invalid viewing area, remained again other useful informations.
Further, when image is sent to external system, can adjusts in external system and show control and described images match for the image showing image, will avoid printing waste.Such as, Fig. 6 illustrates by the image display effect seen in diagnosis report, and before adjustment, containing more black region in the image display area 61 in left side, these are all inactive area, and printing is waste resource; And after the adjustment of above-mentioned image storage method of the present disclosure, image display area 62, gives territory, effective display area all as much as possible by maximum viewing area, avoid printing waste.
