The Micro-Vertex Detector (MVD) of the CBM experiment will be located close to the collision point and exposed to very high track densities from heavy ion collisions produced at high interaction rates. The design of the MVD requires a detailed knowledge of the detector occupancies and the corresponding data rates, which were simulated in this work. The first step of the study was to determine t...

Magnetic resonance imaging (MRI) is a diagnostic imaging technique that uses a magnetic field and radio waves rather than xrays to produce highly detailed images of internal organs and tissues. Because of the high contrast sensitivity to soft tissue and the safety to the patient resulting from the use of nonionizing radiation, MRI has replaced many CT methods. The technique has proven very valu...

Magnetic resonance imaging (MRI) guidance for coronary interventions offers potential advantages over conventional x-ray angiography. Advantages include the use of nonionizing radiation, combined assessment of anatomy and function, and three-dimensional assessment of the coronary arteries leading to the myocardium. These advantages have prompted a series of recent studies in this field. Real-ti...

Public concerns about potential health risks of intermediate-frequency (IF) electromagnetic fields are increasing, especially as the use of induction-heating cooktops has spread extensively in Japan and Europe. In order to investigate the properties of IF electromagnetic fields, we examined the effect of exposure to a 23-kHz IF magnetic field of 2 mT for 2, 3, or 4 h on neutrophil chemotaxis an...

Transillumination breast spectroscopy (TiBS) uses nonionizing optical radiation to gain information about breast tissue morphological and structural properties. TiBS spectra are obtained from 232 women and compared to mammographic density (MD) quantified using Cumulus. The ability of TiBS to estimate MD is assessed using partial least-squares (PLS) regression methods, which requires TiBS spectr...

RATIONALE Inflammatory myofibroblastic tumor (IMT) is an uncommon mesenchymal neoplasm, and its presence in a grafted liver is exceedingly rare. PATIENT CONCERNS A 54-year-old woman was admitted to our hospital with a half-month history of intermittent melena. She had undergone deceased-donor liver transplantation (LT) for hepatitis B virus related liver cirrhosis without hepatocellular carci...

Diffuse optical tomography (DOT) is a noninvasive, nonionizing imaging modality that uses near-infrared light to visualize optically relevant chromophores. A recently developed dynamic DOT imaging system enables the study of hemodynamic effects in the breast during a breath-hold. Dynamic DOT imaging was performed in a total of 21 subjects (age 54±10  years) including 3 healthy subjects and 18 s...

PURPOSE We report on an integrated system for real-time adaptive radiation delivery to moving tumors. The system combines two promising technologies-three-dimensional internal position monitoring using implanted electromagnetically excitable transponders and corresponding real-time beam adaptation using a dynamic multileaf collimator (DMLC). METHODS AND MATERIALS In a multi-institutional acad...

BACKGROUND Many pregnancy and birth cohort studies investigate the health effects of early-life environmental contaminant exposure. An overview of existing studies and their data is needed to improve collaboration, harmonization, and future project planning. OBJECTIVES Our goal was to create a comprehensive overview of European birth cohorts with environmental exposure data. METHODS Birth c...

Background and purpose: Nowadays High-intensity focused ultrasound (HIFU) as nonionizing radiation is used for cancer treatment. Ultrasound beams when crossing the border of two environments are refracted causing decrease in the beam focusing within a tumor. Also, it may induce damage to normal tissues. In this study, we evaluated the focal depth shift induced by ultrasonic beam refraction. Mat...
