Ultrasonic imaging: safety considerations
Modern ultrasound imaging for diagnostic purposes has a wide range of applications. It is used in obstetrics to monitor the progress of pregnancy, in oncology to visualize tumours and their response to treatment, and, in cardiology, contrast-enhanced studies are used to investigate heart function and physiology. An increasing use of diagnostic ultrasound is to provide the first photograph for b...

متن کاملsafety considerations in cardiovascular magnetic resonance imaging studies
the aim of this review is focusing on the most important safety issues in cardiovascular mri (magnetic resonance imaging) which are categorized as: 1-safety items in patients who referred for stress cardiac mr studies. 2-safety consideration that we must know when a patient with cardiovascular devices referred for any (cardiovascular or non-cardiovascular) mri with focus on new protocols accord...
متن کاملUltrasonic Imaging
The basic principles of ultrasonic B-mode imaging aresummarized. Tissue features that generate contrast andsystem features that control image quality are reviewed inthe context of breast cancer imaging. Approaches to signalmodeling, including B-mode and Doppler techniques, arereviewed to guide methodological design and clinical eval-uation. The article concludes with a b...
متن کاملStatic Coil Design Considerations for the Magnetic Resonance Imaging
One of the main challenges in developing magnetic resonance imaging (MRI) systems is to create a static coil that needs to generate magnetic field density along with the characteristics of optimal homogeneity and magnitude size. To do this, two N42 Block PMs are used and the iron core is designed and optimized in accordance with the dimensions of PM pieces using ANSYS Maxwell software. Then, al...
