Fig. 5 is the schematic diagram for illustrating the CT value according to the bodily tissue of an embodiment, organ and material.

Variable relevant to CT image data is referred to as CT value.According to the Nomenclature Composition and Structure of Complexes, bodily tissue, organ and material have The CT value of themselves.Like this, since bodily tissue, organ and material have the CT value of themselves, so in CT image Part can show that user can be diagnosed by using the state of CT image inspection object with being distinguished.CT value can be as follows Definition.

In the formula, k is constant, μ_tIt is the value of image-region, μ_wIt is the reference value of water.

Bodily tissue, organ and material can have the CT value of themselves, as shown in Figure 5.Firstly, the CT number of air is about It is -1000, and the CT value of water is about 0.The CT value of lung and fat and mammary gland with relatively high air containment is lower, range About -1000 to 0.CT value range with high density, the bone of low air containment, blood, heart, liver and tumour is about 0 to 3000.In this way, since the range of the CT value of bodily tissue, organ and material is different, so being carried out when by using CT image When diagnosis, preferably by setting window width corresponding with the CT value range of interested bodily tissue, organ or material is corresponded to CT image data is shown with window position.

Fig. 6 is illustrated according to the CT value of an embodiment and the schematic diagram of display gray scale.

CT image data is indicated by CT value.For example, the CT image data of 12 bits can be indicated by 4096 CT values, and every The CT value of a pixel can be determined by about from -1024 to 3071 integer.However, the display gray scale of display 420 The number of gray value is likely less than the range of the number of the CT value of CT image data.For example, indicated with 12 bits when CT value and When display 420 is indicated by 8 bits and display 410 shows CT image data, each other due to CT value and display gray scale value Do not match one by one, thus the part in CT image data may due to limited display range and cannot sufficiently show that it is thin Section.

Due to the difference in CT value and display gray shade value in range, so can define CT when showing CT image data The window position of value and window width.The window position WL of typical value as the CT value for including within the scope of the CT value of changeable display gray scale can be with It is the intermediate CT value for the CT value for including within the scope of CT value.The value of every CT value can be set according to linear attenuation coefficient.When window position When WL is relatively low, air or fat with Low emissivity absorption coefficient can clearly be shown, and when window position WL is relatively high, Material (such as bone) with high radiation absorption factor can be clearly shown.

For purposes of illustration only, the CT value range of changeable display gray scale is referred to as interested CT value range.Window width WW refers to Show the number for the CT value for including within the scope of the CT value of changeable display gray scale.For example, the window width WW of interested CT value range It can be 700, and window position WL can be 1000.

Fig. 7 A and 7B illustrate the display image 710, transition diagram 730 and histogram 740 according to an embodiment.

According to an embodiment, the relationship between CT value and display gray scale value can be defined by using transition diagram.Example Such as, as shown in Figure 7 B, in the space that wherein trunnion axis indicates that CT value and vertical axis indicate display gray scale, it can define and show and exist The transition diagram 730 of relationship between CT value and display gray scale.

As shown in Figure 7 B, when the window width WW of interested CT value range 750 and window position WL are defined, in interested CT In the CT value range for including in value range 750, the gradient of transition diagram 730 can be set to be greater than interested CT value range The gradient in CT value range except 750.Processor 410 can be adjusted by adjusting the gradient of transition diagram 730 in predetermined C T value The ratio between the number of CT value and the number of display gray shade value in range.Therefore, in interested CT value range 750, The CT value of CT image data is shown with being distinguished corresponds to different display gray shade values so as not to same CT value.However, emerging feeling In CT value except the CT value range 750 of interest, the CT value of CT image data can be displayed for different CT values corresponding to identical Display gray shade value or display gray shade value difference be less than CT value difference value.To the image data exhibition of interested CT value range 750 Show clear and biggish CT value difference value, and the CT value except interested CT value range 750 shows no or lesser CT Value difference value.In this way, the process that wherein display gray shade value difference is less than CT value difference value is referred to as gray-scale compression.

Fig. 7 A illustrates the display image 710 that wherein CT image data is shown according to the transition diagram 730 of Fig. 7 B.The CT of Fig. 7 A The CT Distribution value of image data is as shown in Fig. 7 B histogram.It is dispensed in the display gray shade value of most 8 bit interested CT value range 750 in while, only a limited number of display gray shade value is dispensed on except interested CT value range 750 CT value range R1 and R2 in, so as to cause gray-scale compression.Correspondingly, even if when there are CT value difference value, the CT of part schemes As data can also be by single gray level expressing.For example, as shown in Figure 7 B, although the CT image data of Fig. 7 A is determined to be in histogram In the CT value range of-the 1000 to -700 of Figure 74 0 have high frequency (frequency number), but from -1000 to - CT value in 700 CT value range is represented as minimum display gray shade value 0, and thus in display image 710, corresponds to The part of the CT value is all shown as black portions 712 and 714.In addition, although the image data corresponding to CT value range R2 is deposited It is in histogram 740, but the CT value of CT value range R2 is represented as maximum display gray shade value 255, and thus aobvious Diagram is as in 710, the part corresponding to the CT value is all shown as white portion 716 and 718.
