Improving 3-D Imaging Breast Cancer Diagnosis Systems Using a New Method for Placement of Near-Infrared Sources and Detectors
The objective of this research was to improve 3-D imaging system by near-infrared light emission in breast tissue to achieve a more accurate diagnosis of tumor. The results of repeated experiments in this research have shown that with this imaging system, a more accurate diagnosis of abnormal area depends on the location of the sources and detectors. Therefore, an optimal location model has bee...
متن کاملInfrared Imaging Devices in Infrared Medical Radiography.
The word “thermograph” often used to describe both an instrument and the product of that instrument has as its roots the Greek words thermos and gruphos. The latter means a sketch or pictorial representation; thus, the graphic arts, scientific graphs, photographs, etc. The former relates to heat or temperature. At first reading, then, the word “thermograph” is most appropriate for a graphical r...
متن کاملHigh-resolution infrared imaging
The hands and mind of an artist are intimately involved in the creative process of image formation, intrinsically making paintings significantly more complex than photographs to analyze. In spite of this difficulty, several years ago the artist David Hockney and I identified optical evidence within a number of paintings that demonstrated artists began using optical projections as early as c1425...
متن کاملMedical near-infrared imaging
The use of near-infrared light in functional medical imaging has gained increasing interest during recent years. Techniques using near-infrared light for imaging can be used to study, e.g., hemodynamic responses on the cortex. Brain activation measurements can be performed using, e.g., MEG or fMRI, which, however, require heavy instrumentation. In medical near-infrared imaging, the instrumentat...
متن کاملI. Near-infrared imaging
As a prerequisite for cosmological studies using adaptive optics techniques, we have begun to identify and characterize faint sources in the vicinity of bright stars at high Galactic latitudes. The initial phase of this work has been a program of Ks imaging conducted with SOFI at the ESO NTT. From observations of 42 southern fields evenly divided between the spring and autumn skies, we have ide...
