We have developed a system for acquiring three-dimensional dynamic images of small tissue volumes. As a first example we explored the real-time response of changes in optical properties inside a human finger caused by partial occlusion of distal veins. 2002 Optical Society of America OCIS codes: (170.0170) Medical optics and biotechnology, (110.0110) Imaging systems, (110.6960) Tomography

High-dynamic-range (HDR) images were embodied by a lot of algorithms. This paper takes notice one of these algorithms, which is iCAM06. iCAM06 has worked color appearance prediction of HDR images based on CIECAM02 color prediction and incorporates the spatial processing models in the human vision system for contrast enhancement. We investigated the effect of user controllable factors of iCAM06 ...

Objective(s): We performed a phase IIa clinical trial of trans-1-amino-3-18Ffluoro-cyclobutane carboxylic acid (anti-18F-FACBC), a synthetic amino acid analog for PET, in patients with metastatic prostate cancer. Methods: The study subjects consisted of 10 untreated prostate cancer patients having lymph node and/or bone metastasis. Five patients underwent whole-body PET 5 and 30 min after intra...

PET (positron emission tomography) is a powerful imaging technique that can provide quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (PET radiopharmaceuticals) in the body. Positrons (ß+) are positively charged beta particles. They are emitted when the atom is proton rich. A positron has only a transient existence. After losing all of its kinetic ene...

One of the main objectives of this series of artworks is to facilitate the emergence of the experiential visual complexity between the animate and inanimate that is otherwise not possible to record. The latent aura of textural presences around us is not always noticeable easily since we tend to consume things too fast. With the rich textures achieved after high-dynamic-range-imaging (HDRI) proc...

PURPOSE The aim of this study is to determine if dynamic optical imaging could provide comparable kinetic parameters to that of dynamic PET imaging by a near-infrared dye/(64)Cu dual-labeled cyclic RGD peptide. METHODS The integrin α(v)β(3) binding RGD peptide was conjugated with a macrocyclic chelator 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) for copper labeling and PET...

We present a technique for embedding high dynamic range (HDR) images with interactive exposure control in a web browser. Multiple exposures are encoded as a combination of several basis images, which are stacked together and displayed with different opacity values. The combination of such basis images yields the resulting exposure image. An intuitive interface based on JavaScript callback funct...
