Abstract: Systems, devices and methods for monitoring hemodynamics are described. The systems and methods generally involve directing light toward an area of the body and detecting the resulting scattered light. The scattered light is detected and an electrical signal representative of the scattered light intensity is generated from the detected light. The electrical signal is analyzed by measuring temporal fluctuations of such signals to monitor pathological states over time including hemorrhagic shock, hypoxia, and tissue graft vascularization. Such monitoring can have significant benefits to patients.

Abstract: The present invention concerns scintillator compositions comprising gadolinium halide and a dopant. The gadolinium halide and dopant material (e.g., GdI3:Ce) has surprisingly good characteristics including high light output, high gamma-ray stopping efficiency, fast response, low cost, good proportionality, and minimal afterglow, thereby making the material useful for various applications including, for example, gamma-ray spectroscopy, medical imaging, nuclear and high energy physics research, diffraction, non-destructive testing, nuclear treaty verification and safeguards, and geological exploration. The timing resolution of the scintillators of the present invention also provides compositions suitable for use in imaging applications, such as positron emission tomography (e.g., time-of-flight PET) and CT imaging.
