Precision imaging for biosensing (INVITED)

2007
Conference Papers

Abstract

Precision imaging is a collection of image sensing techniques involving ultra-high sensitivity, time accuracy, and dynamic range, as well as ultra-low noise. In fact, imaging biological processes often requires sub-milli-lux sensitivity to detect tiny levels of bioluminescence or time-correlated techniques to precisely evaluate the decay time of a fluorophore. In this paper we explore the impact precision imaging will likely have on bioimaging and medical imaging. We also describe VLSI techniques that could enable precision imaging devices in the short and medium term and their relevance to the field of imaging as a whole.

Medical imaging

Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities.

Decay chain

In nuclear science, the decay chain refers to a series of radioactive decays of different radioactive decay products as a sequential series of transformations. It is also known as a "radioactive cascade". The typical radioisotope does not decay directly to a stable state, but rather it decays to another radioisotope. Thus there is usually a series of decays until the atom has become a stable isotope, meaning that the nucleus of the atom has reached a stable state. Decay stages are referred to by their relationship to previous or subsequent stages.

Dynamic range

Dynamic range (abbreviated DR, DNR, or DYR) is the ratio between the largest and smallest values that a certain quantity can assume. It is often used in the context of signals, like sound and light. It is measured either as a ratio or as a base-10 (decibel) or base-2 (doublings, bits or stops) logarithmic value of the difference between the smallest and largest signal values. Electronically reproduced audio and video is often processed to fit the original material with a wide dynamic range into a narrower recorded dynamic range that can more easily be stored and reproduced; this processing is called dynamic range compression.
