by Lisa E. Cole Breast cancer is the most common cancer and the second leading cause of cancerrelated deaths among women. Early detection is considered the best option for reducing morbidity and mammography is the current gold standard for early detection of breast cancer. Microcalcifications are the most common abnormality observed on a mammogram and are early markers for breast cancer. Howeve...

X-Ray Imaging In article 2301002, Xutang Tao, Zeliang Gao, and co-workers report a novel high-temperature X-ray detection crystal of SnTe3O8. SnTe3O8 detector exhibits stable sensitivity 617 μC Gyair−1 cm−2 at 175 °C record low limit 8.19 nGyair s−1 for 120 keV hard X-ray. It shows potential applications in detection.

A solid phase extraction sorbent based on polyaniline/graphene nanocomposite is presented. The structure and morphology of synthesized nanocomposite were investigated by Fourier transform infrared spectroscopy, field emission scanning electron microscopy, X-ray diffraction and thermal gravimetric analysis. The dispersive solid phase extraction was employed to the isolation and preconcentration ...

Large-area avalanche photodiodes have been investigated as 1.9-keV X-ray detectors for the muonic hydrogen Lamb-shift experiment. We report experimental tests carried out for evaluation of the avalanche photodiode capabilities for X-ray detection in the intense radiation and low counting rate environment of experiments with muonic atoms. Several muonic atoms were used and it was shown that the ...

We report the generation of ultrashort, hard-x-ray pulses from a liquid mercury target irradiated by 5 kHz laser pulses. The new x-ray source is designed for time-resolved x-ray absorption spectroscopy as well as imaging applications. This marks the first laser-driven plasma x-ray source that continuously recycles the target material, facilitating maintenance-free operation. Theoretical calcula...

Detection of bone contours in x-ray images is an important step in the computer analysis of medical images. Analog X-ray images are characterized by low contrast ratio value and high variability of their optical properties. Therefore classical segmentation algorithms based on homogeneity criteria are not applicable. In this paper we propose an approach for automatic bone contours detection whic...

Electrophysiology procedures are commonly carried out under guidance of C-arm fluoroscopy, but precise localization of the surgical instruments within the patients anatomy is done using expensive electro-anatomic mapping systems • Potential Alternative: Optical catheter detection, tracking & 3D reconstruction in fluoroscopic X-ray images • State of the Art: i) Gaussian blob detectors[3,4] for d...

The job of aviation security screeners is a highly demanding task. Based on the x-ray image of a passenger bag, a screener has to decide within few seconds only whether the bag is ok or has to be hand-searched. This x-ray screening task includes specific knowledge and visual cognition abilities. The knowledge about which items are prohibited and what they look like in x-ray images of passenger ...
