问题     Want a glimpse of the future of health care? Take a look at the way the various networks of people involved in patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient—no matter where he or she may be.
    Online doctors offering advice based on standardized symptoms are the most obvious example. Increasingly, however, remote diagnosis (telemedicine) will be based on real physiological data from the actual patient. A group from the University of Kentucky has shown that by using an off-the-shelf PDA(personal data assistance) such as a Palm Pilot plus a mobile phone, it is perfectly feasible to transmit a patient’s vital signs over the telephone. With this kind of equipment in a first-aid kit, the cry asking whether there was a doctor in the house could well be a thing of the past.
    Other medical technology groups are working on applying telemedicine to rural care. And at least one team wants to use telemedicine as a tool for disaster response—especially after earthquakes. Overall, the trend is towards providing global access to medical data and expertise.
    But there is one problem. Bandwidth is the limiting factor for transmitting complex medical images around the world—CT scans being one of the biggest bandwidth consumers. Communications satellites may be able to cope with the short-term needs during disasters such as earthquakes, wars or famines. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of distributed medical intelligence.
    Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should usher in an era when telemedicine and the sharing of medical information, expert opinion and diagnosis are common.
The word "problem" in the fourth paragraph refers to the fact that______.
选项 A、there are not enough mobile phones for distributing medical intelligence
B、CT scans are one of the biggest bandwidth consumers
C、bandwidth is not adequate to transmit complex medical images around the world
D、communications satellites can only cope with the short-term needs during disasters
答案C
解析 第四段第一句提到的问题实际上指本段第二句表达的内容。该句可以理解为：宽带是制约着在全球范围内传送复杂的医用图像的一个因素——CT扫描图像是需要宽带传输的数据之一。言外之意是：由于全球范围内计算机网络尚未普遍采用宽带传输数据，致使CT扫描图像无法传送。
