Frequency-domain techniques enhance optical mammography: initial clinical results.
We present a novel approach to optical mammography and initial clinical results. We have designed and developed a frequency-domain (110-MHz) optical scanner that performs a transillumination raster scan of the female breast in approximately 3 min. The probing light is a dual-wavelength (690 and 810 nm, 10-mW average power), 2-mm-diameter laser beam, and the detection optical fiber is 5 mm in di...
متن کاملFrequency-domain optical mammography: edge effect corrections.
We have investigated the problem of edge effects in laser-beam transillumination scanning of the human breast. Edge effects arise from tissue thickness variability along the scanned area, and from lateral photon losses through the sides of the breast. Edge effects can be effectively corrected in frequency-domain measurements by employing a two-step procedure: (1) use of the phase information to...
متن کاملSurvey of Mammography Practice: Initial Results from Serbia
The purpose of this paper is preliminary evaluation the mammography practice in Serbia, having in mind the annual number of examinations and fact that part of examination is performed on women without any clinical signs. For initial evaluation, five hospitals with highest workload have been selected, representing the typical mammography practice in Serbia. The methodology consists of initial im...
متن کاملOptical frequency domain imaging vs. intravascular ultrasound in percutaneous coronary intervention (OPINION trial): one-year angiographic and clinical results
Aims Optical frequency domain imaging (OFDI) is a recently developed, light-based, high-resolution intravascular imaging technique. Intravascular ultrasound (IVUS) is a widely used, conventional imaging technique for guiding percutaneous coronary intervention (PCI). We aimed to demonstrate the non-inferiority of OFDI-guided PCI compared with IVUS-guided PCI in terms of clinical outcomes. Meth...
متن کاملGauge techniques in time and frequency domain
Typical features of the Transmission Line Matrix (TLM) algorithm in connection with stub loading techniques and prone to be hidden by common frequency domain formulations are elucidated within the propagator approach. In particular, the latter reflects properly the perturbative character of the TLM scheme and its relation to gauge field models. Internal ‘gauge’ degrees of freedom are made expli...
