Abstract |
Diffuse optical tomography (DOT) is a noninvasive diagnostic imaging technique which uses near infrared (NIR) light to measure optical properties of tissue. Absorption and scattering are the major optical properties of the tissue which can characterize tissue functional and metabolic activities. The basic idea of diffuse optical tomography imaging is to illuminate the tissue with an array of light sources and to measure the light leaving the tissue with an array of detectors. DOT imaging system comprises light illuminating and light detector system, and a controlling unit. The controlling unit controls and synchronizes various components of the DOT system to acquire high speed optical measurement data. The data are sent to a high performance computing unit to reconstruct high speed 3D- DOT image. In this project, high power LED will be used to illuminate the tissue because of its simple design, fast response times, good intensity characteristics, cost effective and efficient modulation up to 100 to 150 MHz. For the detection of the diffused light Silicon photo detectors will be used as it is cost effective and compact. In this project, building of an instrument which can illuminate tissue and measure diffused light at high speed as well as accurately is the aim. To achieve high speed controlling, compact design and fast data acquisition, Raspberry Pi is used. By building such a system cost effective high speed optical data measurement can be achieved along with a compact design and good accuracy. |
