Wide-dynamic-range sensors

Orly Yadid-Pecht, MEMBER SPIE Ben-Gurion University of the Negev Electrical and Computer Engineering Department P.O. Box 653 Beer-Sheva 84105 Israel E-mail: [email protected] Abstract. The work done to provide image sensors (CCDs and CMOS) with a wide dynamic range is reviewed. The different classes of solutions, which consist of logarithmic sensors, ‘‘clipped’’ sensors, multimode sensors, frequ...

Wide dynamic range imaging

Interest in technologies that can help improve image sensors—in terms of cost, noise and dynamic range—is growing as quickly as the market for them. Dynamic range (DR) quantifies the ability of a sensor to image highlights and shadows. If we define the dynamic range of the sensor as 20 log(S/N), where S is the maximal signal value and N is the sensor noise, the typical image sensors will have a...

Quantum mechanical proton range in human body

Introduction: Proton therapy delivers radiation to tumor tissue in a much more confined way than conventional photon therapy thus allowing the radiation oncologist to use a greater dose while still minimizing side.   Materials and Methods: protons release most of their energy within the tumor region. As a result, the treating physician can potentially give an...

Wide dynamic range MR elastography of liver

Introduction: The dynamics of the complex shear modulus of biological tissue is determined by rigidity and connectivity of cells. Thus, measuring the frequency dispersion of G* of an organ can provide a macroscopic parameter which is related to the mechanical microstructure and therewith to the state of health of tissue. Magnetic Resonance Elastography (MRE) is capable of determining G* in vivo...
