【摘要】 阐述了非接触式近红外荧光断层成像中光从介质表面出射后的传播.在Jorge Ripoll等人工作的基础上,考虑了镜头的空间透视效应,简化了光在自由空间中的能量传播模型,建立了介质表面光强与CCD探测强度的联系.仿体实验结果表明该模型能够有效应用于非接触式近红外荧光断层成像.更多还原

【Abstract】 Light propagation from the object boundary to detector was presented for non-contact near infrared fluorescent molecular tomography(FMT).Based on the work of Jorge Ripoll et al,perspective projection effect of lens was considered.The formula for light intensity transport in free-space was simplified.The relationship of the light intensity distribution on object boundary and the value obtained by CCD camera was established.Phantom experiment results confirm that this model is an efficient approach for non-contact near-infrared fluorescent molecular tomography.更多还原
