高性能計算機斷層掃描(CT)能夠在40秒之內即可完成整個機體的掃描，能夠顯示任何病變。這些總體掃描具有廣泛的應用范圍，從快速完整地檢查事故受害者，檢測腫瘤轉移和關節炎，甚至虛擬尸體解剖，而這對死者家屬在感情上更容易接受。

這種新進展令人鼓舞，開拓了新型診斷方法的可能，但是專家警告不可濫用。10年以前，患者接受完整的CT或者核磁共振(MRI)需要數小時之多。那時候掃描時間十分漫長，而且在CT檢查時高暴露于放射線。

Total Body Scans Produced in Only 40 seconds
 
High-performance computed tomography (CT) can scan an entire human body in just 40 seconds and is able to show anything that is problematic. These total body scans have a range of applications, from quick, complete examinations of accident victims and the detection of cancerous metastases and arthritis, to new methods of virtual autopsy that are emotionally easier on surviving family members.

This new development is generating excitement and opening up new diagnostic possibilities, yet specialists warn of abuse. Less than 10 years ago, it took several hours to complete a scan on a patient with CT or magnetic resonance imaging (MRI). That was an unreasonably long scan time and in the case of CT entailed very high exposure to radiation.
