We report the first application and usefulness of image transfer through a mobile telephone, which can be used between the hospital and another location.
With this system, brain computed tomographic scans, magnetic resonance images, and angiograms obtained from more than 100 patients in the emergency department were transferred and diagnostically analyzed via a mobile phone. The mobile phone had a 110,000-pixel digital camera and a built-in thin-film transistor liquid crystal display. We reviewed the distribution of pathological characteristics on the transferred images and compared them with the diagnoses made using full-scale original film.
This system of transferring images was useful in all cases for correct early diagnosis and early treatment. The quality of magnetic resonance images received was better than that of computed tomographic scans. Hemorrhage provided better contrast than infarction for allowing easy identification. Cerebral angiography revealed small aneurysms if the target area was focused properly. Image quality was sufficient for interpretation despite the small dimensions of the monitor. Ease of operation and portability were both satisfactory. The mean time from commencement of image uptake to complete reception was 2 to 3 minutes.
The mobile phone system is adequately useful for early diagnosis and initiation of treatment in emergent cases. This is attributable to its low cost and ease of handling for sending images to remote areas and between hospitals, despite the small dimensions of the monitor. Better-quality image transfer will be realized through an advanced mobile phone system based on the new International Mobile Telecommunication 2000 standards, which also will be useful in the development of telemedicine and telecare.
我们报告了通过移动电话进行图像传输的首次应用及其效用，该方式可在医院与其他地点之间使用。
利用此系统，对急诊科100多名患者的脑部计算机断层扫描、磁共振图像和血管造影进行了传输，并通过移动电话进行诊断分析。该移动电话配有11万像素的数码相机和内置薄膜晶体管液晶显示屏。我们查看了传输图像上病理特征的分布情况，并将其与使用全尺寸原始胶片做出的诊断进行比较。
这种图像传输系统在所有病例中都有助于正确的早期诊断和早期治疗。接收的磁共振图像质量优于计算机断层扫描图像。出血比梗死的对比度更好，便于识别。如果目标区域聚焦得当，脑血管造影可显示小动脉瘤。尽管显示器尺寸较小，但图像质量足以进行解读。操作简便性和便携性均令人满意。从开始摄取图像到完整接收的平均时间为2至3分钟。
移动电话系统在紧急情况下对早期诊断和治疗启动具有充分的效用。这归因于其成本低且便于将图像发送到偏远地区以及医院之间，尽管显示器尺寸较小。基于新的国际移动电信2000标准的先进移动电话系统将实现更高质量的图像传输，这在远程医疗和远程护理的发展中也将发挥作用。
