Physics and statistics of medical imaging

asymptotic property of order statistics and sample quntile

چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...

Physics and applications of medical imaging

Medical imaging is the principal method for noninvasively obtaining anatomic and physiologic information about the human body. Imaging has experienced a quantum leap in technology and clinical applications over the past 25 years. This leap includes x-ray computed tomography (CT); emission computed tomography (SPECT and PET); magnetic-resonance imaging (MRI) and spectroscopy (MRS), including fun...

Medical imaging and physiological modelling: linking physics and biology

Medical image analysis is increasingly providing a sophisticated set of tools for processing measurement inputs into clinically relevant outputs, although this is, on the whole, completed without consideration of the underlying physiology. In contrast, physiological modelling provides a predictive tool based on a physical and biological understanding of the underlying processes. In this editori...

ETHICAL ISSUES IN MEDICAL STATISTICS

Medical statistics (biostatistics), as a vital essential part of modem life, does raise some fundamental ethical issues. Surprisingly, this aspect seems to have been totally ignored by books on medical ethics. This paper discusses how the statistical aspects affect the ethics. The relation between biostatistics and medical research is explored. All stages of a medical research exercise are ...
