摘要:
脑血流和灌注可以通过示踪剂稀释实验来估计。血流参数的准确估计是医学影像中有效诊断和治疗的关键部分。本研究探讨两个主题:(i)作为响应示踪剂输入的Gamma变量函数的推导,以及(ii)通过最小二乘法从示踪剂稀释曲线参数估计脉冲函数和残留函数。
英文摘要:
Cerebral blood flow and perfusion can be estimated using tracer dilution experiments. Accurate estimation of blood flow parameters is a crucial part of medical imaging for effective diagnosis and treatment. This study explores two themes: (i) the derivation of the gamma variate function as a response tracer infusion and (ii) the estimation of impulse and residue functions from tracer dilution curves parameters via the least squares method.
