Dual-Direction Optical Measurement Instrument for Assisting X-Ray Mammography

Dual-direction Measuring System of Near Infrared Optical Tomography Combined with X-ray Mammography

This study is to develop a dual-direction measuring instrument of diffuse optical tomography in the continue-wave domain to be incorporated with an X-ray mammography system for the aid of obtaining functional images to detect breast tumors. The device is handled to compress breast-like phantoms by two slabs with sources and detectors which a multiple-channel switching was designed for. Obtained...

Comparison of Singh index accuracy and dual energy X-ray absorptiometry bone mineral density measurement for evaluating osteoporosis

Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...

Optical klystron FEL scheme for x-ray coherent harmonic generation at ISLF storage ring

The possibility of inserting an optical klystron on the storage ring of an Iranian Light Source Facility as a Synchrotron Radiation Free electron Laser for coherence harmonic generation in the soft x-ray spectrum has been studied. The study has been performed using the 3D FEL simulation code GENESIS 1.3 and in accordance with the available characteristic parameters of ISLF. Different potential ...

Comparison of Bone Mineral Density Measured by Dual X-ray, Axial Dual-energy Photon X-ray Absorptiometry and Laser Absorptiometry of Calcaneus

The objective of this study was to validate the use of bone mineral measurements of the calcaneus bone by dual X-ray and laser (DXL) in a cross-sectional study carried out in an osteoporosis clinic. Measurements of bone mineral density (BMD) at proximal femur and spine were obtained by dual-energy photon X-ray absorptiometry (DEXA). Osteoporosis was defined by a DEXA T-score <-2.5 at the femora...
