Display screen 2 is comprised of three two dimension view windows and a 3-D view window, and three two dimension view windows are respectively cross-section position window, sagittal plain window, Coronal window.
Image two-dimensional process device 8 is made of image base conditioning device and image Scissoring device two parts.Image base conditioning device comprises for the filtering of single width image to be processed and processes for the arithmetical operation of two width of cloth images.The image Scissoring device generally can be analyzed all image datas, reaches more flexibly mode of operation for obtaining better contrast, and the user can carry out trimming operation and come selection portion subregion data to carry out the image processing operation.
The image three-dimensional treating apparatus reaches " video production " two parts by " volume drawing " and forms.
Each point in the middle of the volume data can distribute emission and the absorption parameter of a light.Like this, by the in vivo propagation of section of simulation light, just can realize the demonstration of volume data under the visual angle condition.
The volume render operation step is as follows:
(1) in data management system, choose need the image of executable operations node after, click the check box on " volume drawing " left side.The ample resources of processor can be taken when carrying out volume render operation, therefore the implementation effect that to see volume drawing a moment need be born with.This equipment provides 5 kinds of volume rendering algorithms can supply user selection a kind of volume drawing of carrying out wherein:
The GPU light projecting algorithm
GPU maximum intensity projection algorithm
GPU tangent plane algorithm
The GPU light projecting algorithm
GPU maximum intensity projection algorithm
(2) select " presetting " Shipping Options Page.
1. click " selecting default volume drawing transfer function " button, just can the inner definition of choice for use or preset value commonly used.
" CT Generic " is the preference of transfer function acquiescence.
" CT Black﹠amp; White ", do not use any color, because some image can be covered useful information after painted.
" CT Cardiac " can strengthen the details of heart CT image.
" CT Bone " highlights bone, and makes other position more transparent.
" CT Bone (Gradient) " highlights bone, but uses the mode of ladder to show other organ surface.
The transfer function of the acquiescence that " MR Generic " adopts when reading magnetic resonance imaging (magnetic resonance imaging is rule unlike the CT image).
2. preserve and loading preset value commonly used
Behind establishment or the editor's transfer function, self-defined transfer function can be stored, and reapplication is in file system.Click " preservation " (" loading ") button, can with threshold value, color and gradient function in conjunction with rear preservation (loading) in * .xml formatted file.
3. gray value interval adjustment
Adjust gray-scale value scope corresponding to all function generators by adjusting slide block, or amplify the value range of " gray-scale value scope " window.
4. opacity mapping function generator
The gray-scale value of this point will be mapped to the transparence value of setting.Transparence value is to be shown as all-transparent at 0 o'clock, and value is to be shown as entirely opaque at 1 o'clock.
5. color map function generator
The gray-scale value of this point will be mapped to the color of setting.
6. gradient variable exchange the letters number generator
The size of gray-scale value conversion and the mapping between the opacity are set, are used for some specific gray-scale value of control.
All can comprise following operation when customizing above three kinds of function generators:
The left button of clicking the mouse increases point of adjustment.
The right button of clicking the mouse deletion point of adjustment.
Clicking and pin left mouse button can be used for drags and regulates already present point of adjustment.
(3) except the direct editing transfer function, the image three-dimensional treating apparatus also provides two kinds of figures commonly used that can automatically produce transfer function, i.e. threshold figure and bell figure.This dual mode all comprises two parameters, and up/down and left/right rolling mouse after clicking the cross figure can be used for revising parameter value.
First parameter is for " " center " (controlling its size by the parallel mouse) is used to specify the gray-scale value of the centre of figure that will be loaded.
Second parameter is " width " (controlling its size by vertical rolling mouse), is used to specify the width (or gradient steepness) of figure.
1. select " threshold value " Shipping Options Page can activate the threshold function table generator that creates the threshold value figure.The threshold value figure originates in zero point and is promoted to " " center " parameter value.Width value is less, and the figure of threshold function table is more precipitous.
2. click " bell " Shipping Options Page and can activate the threshold function table generator that creates bell figure.The threshold value figure originates in zero point, is promoted to " to drop to zero point behind the " center " parameter value again." width " parameter value is corresponding to the width of bell figure.
The image processing result can preserve video or view screenshotss by making video record.
Image measuring device can make user and bidimensional image or contain storehouse and individual image dough sheet of the three-dimensional of graphics plane data type carries out interactive operation.It can measuring distance, angle, path and some geometric figures.After carrying out the measurement operation, the identical or different measurement pattern with the selected correction of image can be preserved, in order in the future used.When image has been drawn a plurality of figure, the current application figure is shown in red, and all the other Graphics Applications then are shown as white, and the displayed value on the image is the rreturn value of current application figure.All measurement pattern all can each self-generating the node of an image tree in data management system, show.The single measurement pattern that no longer needs or image can be deleted one by one in data management system or delete as one group of integral body.
The Image registration device reaches " non-rigid registration " three parts by " some registration ", " rigid registration " and forms.The medical image registration refers to one group of medical image behind spatial alternation, makes it and another group keep corresponding point on the motionless medical image to reach consistent on the space.Keep motionless being called with reference to image, conversion is called unsteady image.The result of registration is applied to the image that floats.
The Image Segmentation device can be that anatomical structure and pathologic structure establishment are cut apart at the medical image of human body.Comprise Interactive Segmentation and blood vessel segmentation two parts.Below take liver as example, the principle of work of Image Segmentation device is described.
Blood vessel segmentation comprises based on the blood vessel segmentation of threshold value with based on two steps of reconstructing blood vessel of model.
Use this equipment and can be achieved as follows several functions:
1, art preplanning
