ABSTRACT
Purpose:
This study was aimed to develop a fusion imaging system of multi-channel near-infrared spectroscopy (NIRS) and ultrasonography (USG) for imaging prostate cancer and to verify its diagnostic capability for imaging prostate cancer with applying the hybrid imaging system to prostate cancer phantom.
Methods:
A multi-channel NIRS system using near-infrared wavelengths 785 nm with 12 channels and 4 detectors was developed. After arranging the optical fibers around USG transducer, we performed NIRS imaging and Gray-scale USG imaging simultaneously. Fusion imaging was obtained by processing incoming signals and spatial reconstruction of NIRS, which was corresponding with gray-scale USG acquired at the same time. Developed NIRS-USG hybrid system was applied to the silicone-based optical phantoms of the prostate gland including prostate cancer to verify its diagnostic capability qualitatively.
Results:
Developed NIRS-USG hybrid imaging system for prostate cancer imaging simultaneously provides anatomical and optical information with 2-D registration. The hybrid imaging system showed more NIR attenuation over the prostate cancer than over normal prostate gland. Its diagnostic capability to discriminate focal area mimicking optical properties of prostate cancer from surrounding backgrounds mimicking those of normal prostate gland was verified by applying the hybrid system to a silicon-based optical phantom of the prostate cancer.
Conclusion:
This study successfully demonstrated the possibility of the NIRS-USG hybrid system as a new potential imaging method for improving the diagnostic accuracy of prostate cancer and demonstrates its utility for future clinical application.
