An Artificial neural network has been applied for pattern recognition and used as a tool in an expert system. The purpose of this study is to examine the potential usefulness of the neural network approach in medical applications for image recognition. Multilayer feedforward neural networks with a back-propagation algorithm is designed for this study. Using first-pass radionuclide venticulograms, we attempted to identify the right and left ventricles of the heart and the lungs by training the neural network from patterns of time-activity curves. In a preliminary study, the neural network enabled identification of the lungs and heart chambers once the network was trained sufficiently by means of repeated entries of data from the same case. Thus neural networks can assist in solving complex problem in the medical field because they can recognize and discriminate certain patterns after training with many examples.

人工神经网络已被应用于模式识别，并用作专家系统的工具。本研究的目的是研究神经网络方法在医学图像识别应用中的潜在有用性。多层前向神经网络与反向传播算法设计了这项研究。使用首过放射性核素心室图，我们试图通过从时间-活动曲线的模式训练神经网络来识别心脏和肺的右心室和左心室。在一项初步研究中，一旦通过重复输入同一病例的数据对网络进行充分训练，神经网络就能够识别肺和心腔。因此，神经网络可以帮助解决医学领域的复杂问题，因为它们可以在经过许多示例训练后识别和区分某些模式。
