There are several imaging techniques available to the clinician today. The clinical evaluation of a new method such as applied potential tomography (APT) raises a number of questions and these are reviewed in this paper. In particular, the advantages of APT over other methods are stressed. It is considered to be harmless both to the patient and the clinical staff, it is easy to apply and there is no discomfort to the patient during the imaging procedure. The main drawback of this new and inexpensive imaging method appears to be its low resolution. Several clinical applications of APT have already been investigated and others are anticipated in this paper. Each application is reviewed in some detail and the value of dynamic imaging is emphasised in several cases. The most promising clinical application of APT so far has been the monitoring of gastric emptying.
如今临床医生可使用多种成像技术。对诸如应用电位断层扫描（APT）这样的新方法进行临床评估会引发一些问题，本文将对此进行综述。特别强调了APT相对于其他方法的优势。它被认为对患者和临床工作人员均无害，易于应用，且在成像过程中患者不会感到不适。这种新型且廉价的成像方法的主要缺点似乎是其分辨率较低。APT的几种临床应用已经得到研究，本文还预期了其他一些应用。对每种应用都进行了较为详细的综述，并在一些案例中强调了动态成像的价值。迄今为止，APT最有前景的临床应用是监测胃排空。
