MIC-II is a versatile BASIC computer program designed to calculate the cardiac output, the arterio-venous shunt and the regional blood flow from data obtained by the radioactive microsphere method. The samples are measured in a gammaspectrometer with a multichannel pulse height analyzer and the data are recorded on tape. Up to 10 different nuclides may be used simultaneously, including tracers which are not bound to microspheres. The nuclides may have overlapping energy spectra. The analysis of the energy spectra is performed according to the matrix method. Standard samples, each containing one pure nuclide, are measured to obtained the overlap matrix. The unkown amounts of the nuclides in the samples are obtained by solving a system of simultaneous linear equations. Up to 100 organ samples may be taken in one experiment. Up to 10 different organ maps, containing a text label for each organ specimen, may be created, edited, modified and stored on tape for convenient identification of input and output. Numerous validity checks for imput and output make MIC-II easy to use, even for non-computer trained personel.
MIC-II是一个多功能的BASIC计算机程序，旨在根据放射性微球法获得的数据计算心输出量、动静脉分流和局部血流量。样本在配备多通道脉冲高度分析仪的伽马能谱仪中进行测量，数据记录在磁带上。最多可同时使用10种不同的核素，包括未与微球结合的示踪剂。这些核素可能具有重叠的能谱。能谱分析根据矩阵法进行。测量每个包含一种纯核素的标准样本以获得重叠矩阵。通过求解联立线性方程组获得样本中核素的未知量。在一次实验中最多可采集100个器官样本。最多可创建、编辑、修改并存储在磁带上10种不同的器官图谱，每个器官标本都有一个文本标签，以便于输入和输出的识别。对输入和输出进行的大量有效性检查使MIC-II易于使用，即使对于未受过计算机培训的人员也是如此。
