Body Surface Potential Mapping (BSPM) is a new tool in electrocardiography for imaging cardiac potentials measured at the torso skin, and potentially for imaging epicardial potentials, BSPM can be used to localize electrical foci in the heart as in WPW syndrome, infarction, or normal conduction, but the technology for a practical BSPM system is just now available. Our objective is a stand-alone portable BSPM system requiring minimal operator assistance in acquiring data from 180 electrodes, producing images of potentials on the torso skin, extracting features of the image sequences in a report to clinicians, and providing some analysis of those features as an aid to the clinician. In Phase I, we will concentrate on the remaining hardware and software problems in data acquisition, so that good quality data can be recorded from patients from infants to adults. In Phase II, emphasis will shift to research on processing and analyzing the potential data as a three dimensional set of values, where information is encoded in the three dimensional features. With a safe reliable system for efficient acquisition (Phase I), and analytical software (Phase II), a commercial instrument should emerge.

体表电位标测（BSPM）是一种新的心电图工具 用于对在躯干皮肤处测量的心脏电位进行成像，并且可能 对于心外膜电位成像，BSPM可用于定位电 心脏病灶，如WPW综合征、梗死或正常传导，但 用于实际BSPM系统的技术才刚刚可用。 我们 目标是一个独立的便携式BSPM系统，需要最少的操作员 协助从180个电极采集数据， 在躯干皮肤上的电势，提取图像序列的特征， 一份报告给临床医生，并提供一些分析，这些功能作为一个 帮助临床医生。 在第一阶段，我们将集中精力解决剩余的问题。 数据采集的硬件和软件问题，使质量好 可以记录从婴儿到成人的患者的数据。 在第二阶段， 重点将转移到研究处理和分析潜在的 数据作为三维值集，其中信息被编码为 三维特征。 安全可靠的系统， 收购（第一阶段）和分析软件（第二阶段），商业 工具应该出现。
