Embodiment 1
[0081] Figure 8 Shown is an image of an exponentially adjusted deep tissue containing a tumor. image 3 Shown is a real image of a tumor deep within the tissue, where the target is 6 mm in diameter and the tumor is 3.8 cm below the tissue.
[0082] Compared image 3 ,As can be seen, Figure 8 , the accuracy of tumor location is very high, with very good imaging results.
[0083] In this example, the adjustment index a=2.5 in the adjustment weight M, and the dynamic range of the adjustment parameter R=129470.
Embodiment 2
[0085] Figure 8 Shown is the superficial layer of tissue containing a 6 mm diameter tumor with the tumor located 1.2 cm below the tissue. Figure 10 It is the imaging effect diagram of the exponential adjustment target detection device of the present invention.
[0086] It can be seen that the exponentially adjusted target detection device also has a very ideal imaging effect on tumors in the superficial tissue.
[0087] In this example, the adjustment index a=1, and the dynamic range of the adjustment parameter R=111.
Embodiment 3
[0089] Figure 11 Shown is a real image of tissue containing multiple tumors. And these tumors had different depths, 1 cm, 2 cm, and 3 cm below the tissue, respectively. Each tumor was 8 mm in size. Figure 12 Imaging renderings of the prior art. Figure 13 It is the imaging effect diagram of the exponential adjustment target detection device of the present invention.
[0090] It can be seen from the imaging effect that the existing near-infrared imaging equipment cannot detect tumors deep in the tissue; however, in the exponentially adjusted target detection device of the present invention, three tumors can be accurately detected; and it has a position error comparison Small, the overall imaging effect is good. This shows that the exponentially adjusted target detection device also has a good detection ability for multiple tumors of different depths.
[0091] In this example, the adjustment index a=1.8, and the dynamic range of the adjustment parameter R=4795.
