We have studied the use of image intensification in a trauma theatre over a period of 6 months with particular reference to the acquisition of intraoperative image intensifier thermal prints instead of formal radiographs. The quality of the prints and the savings generated have been assessed. During the study period, 476 patients underwent orthopaedic trauma procedures. The image intensifier was used for intraoperative screening in 280 patients. In 278 of these a thermal print was obtained. This was used, instead of formal check radiographs, to plan further management in 210 patients (75%). In 68 patients, the printout was insufficient in its coverage of the operated area, and a check radiograph was also obtained. In no case did the clarity of the thermal image hinder accurate interpretation. We believe that thermal images are a useful substitute for formal postoperative radiographs in many trauma cases, and that, with notable exceptions, their use could decrease costs, reduce patient discomfort and radiation dose and spare overloaded radiology services.
我们在创伤手术室对影像增强技术的应用进行了为期6个月的研究，特别关注术中影像增强器热敏打印片的获取，而非传统的X光片。我们评估了打印片的质量以及所产生的费用节省情况。在研究期间，476例患者接受了骨科创伤手术。280例患者在术中使用了影像增强器。其中278例获得了热敏打印片。在210例患者（75%）中，该打印片被用于替代传统的复查X光片以规划进一步的治疗。在68例患者中，打印片对手术区域的覆盖不足，因此还获取了复查X光片。在任何情况下，热成像的清晰度都不会妨碍准确解读。我们认为，在许多创伤病例中，热成像可有效替代传统的术后X光片，并且在大多数情况下，其使用可降低成本、减轻患者不适并减少辐射剂量，还可减轻放射科的负担。
