159 epidemiology. They expand on difficult concepts that their colleagues merely label and focus these topics as the essence of epidemiological issues. Issues presented are not complicated by elaborate vocabulary or intricate statistical detail. Those difficult statistical techniques are explained in a manner that attains the essence of statistical sophistication without becoming too simplistic...
متن کاملVideo-rate tomographic phase microscopy.
Tomographic phase microscopy measures the 3-D refractive index distribution of cells and tissues by combining the information from a series of angle-dependent interferometric phase images. In the original device, the frame rate was limited to 0.1 frames per second (fps) by the technique used to acquire phase images, preventing measurements of moving or rapidly changing samples. We describe an i...
متن کاملVideo-rate functional photoacoustic microscopy at depths.
We report the development of functional photoacoustic microscopy capable of video-rate high-resolution in vivo imaging in deep tissue. A lightweight photoacoustic probe is made of a single-element broadband ultrasound transducer, a compact photoacoustic beam combiner, and a bright-field light delivery system. Focused broadband ultrasound detection provides a 44-μm lateral resolution and a 28-μm...
متن کاملMeasuring microlymphatic flow using fast video microscopy.
Despite advances in the measurement of lymphatic function, little is known about the actual velocities of flow in microlymphatic ( approximately 100 mum diam) vessels. In this work, video microscopy and particle tracking methods are adapted and integrated with an ultra-high-speed imaging camera to obtain measurements of lymph velocities throughout the entire lymphatic contraction cycle in the r...
متن کاملOn the limits of digital video microscopy
– We explore the limits of digital video microscopy which is established as a standard method in physics, chemistry and biology. At particle distances close to contact we observe small but systematic deviations between the optically measured and the real particle distances. This difference is caused by the overlap of the optical images between neighboring particles. Exemplarily we discuss the c...
