Optical mammography combined with fluorescence imaging: lesion detection using scatterplots
نویسندگان
چکیده
Using scatterplots of 2 or 3 parameters, diffuse optical tomography and fluorescence imaging are combined to improve detectability of breast lesions. Small or low contrast phantom-lesions that were missed in the optical and fluorescence images were detected in the scatterplots. In patient measurements, all tumors were visible and easily differentiated from artifacts and areolas in the scatterplots. The different rate of intake and wash out of the fluorescent contrast agent in the healthy versus malignant tissues was also observed in the scatterplot: this information can be used to discriminate malignant lesion from normal structures.

Foliar Disease Detection in the Field Using Optical Sensor Fusion
The objective of this research was to detect and recognize the plant stress caused by disease in the field conditions by combining hyperspectral reflection information between 450 and 900nm and fluorescence imaging. The results can be used to develop a tractor mounted cost-effective optical device for site-specific pesticide application in order to reduce and optimize pesticide use. The work re...

Introduction & Objective: The breast cancer is the most common malignancy in women and in recent years it is seen in younger ages. Because of dense breast tissue in these ages, the mammography sensitivity for breast cancer detection is reduced, so high quality ultrasonography (US) as a combined screening method is effective. The aim of this study is the evaluation of the mammographic finding ...

The breast cancer is common in females.Early detection with safe , convenient , noninvasive and accessible diagnostic tools are important. X- ray mammography is still the first choice imaging for breast cancer, but has low specificity and limited value in dense breast and surgically scarred breasts. In recent years , MIBI scintimammography has been used for this purpose. The...

Breast cancer is one of the most common cancers among the population of the Western world. Diagnostic methods include mammography, ultrasound, and magnetic resonance; meanwhile, nuclear medicine techniques have a secondary role, being useful in regional assessment and therapy followup. Optical imaging is a very promising imaging technique that uses near-infrared light to assess optical properti...
