Richard Satava, program manager for advanced medical technologies, has been a driving force in bringing virtual reality to medicine, where computers create a "virtual" or simulated environment for surgeons and other medical practitioners (从业者). "With virtual reality we"ll be able to put a surgeon in every trench," said Satava. He envisaged a time when soldiers who are wounded fighting overseas are put in mobile surgical units equipped with computers. The computers would transmit images of the soldiers to surgeons back in the U.S. The surgeons would look at the soldier through virtual reality helmets (头盔) that contain a small screen displaying the image of the wound. The doctors would guide robotic instruments in the battlefield mobile surgical unit that operate on the soldier. Although Satava"s vision may be years away from standard operating procedure, scientists are progressing toward virtual reality surgery. Engineers at an international organization in California are developing a tele-operating device. As surgeons watch a three-dimensional image of the surgery, they move instruments that are connected to a computer, which passes their movements to robotic instruments that perform the surgery. The computer provides feedback to the surgeon on force, textures, and sound. These technological wonders may not yet be part of the community hospital setting but increasingly some of the machinery is finding its way into civilian medicine. At Wayne State University Medical School, surgeon Lucia Zamorano takes images of the brain from computerized scans and uses a computer program to produce a 3-D image. She can then maneuver the 3-D image on the computer screen to map the shortest, least invasive surgical path to the tumor (肿瘤). Zamorano is also using technology that attaches a probe to surgical instruments so that she can track their positions. While cutting away a tumor deep in the brain, she watches the movement of her surgical tools in a computer graphics image of the patient"s brain taken before surgery. During these procedures—operations that are done through small cuts in the body in which a miniature camera and surgical tools are maneuvered—surgeons are wearing 3-D glasses for a better view. And they are commanding robot surgeons to cut away tissue more accurately than human surgeons can. Satava says, "We are in the midst of a fundamental change in the field of medicine. " (392 words )
单选题
According to Richard Satava, the application of virtual reality to medicine______.
【答案解析】解析：本题属于细节辨析题。文中涉及Satava的句子并不多，我们可以迅速定位到第二段第二句，其中“envisage”和“has visions of”对应，本句大意：他设想可以将海外受伤的士兵放在配有计算机的移动手术病房里。接着的第三段大意：计算机将把士兵伤口的图像传给远在美国的戴着头盔的医生，头盔上会有图像显示。根据以上内容，答案可以确定为A“使用远程控制技术来治疗在海外受伤的士兵”。B“受伤的士兵在战场上被带着头盔的医生救治”，错在“on the battlefield”，因为原文说带着头盔的医生并不要亲临战场；C“受伤的士兵由受到特别训练的医生手术”，原文没有提及；D“在海外建立移动手术病房”，和答案沾点边，但并不确切，没有说出虚拟现实技术的实质。
