A medical system or workstation typically contains basic computer components such as CPU, hard disk, network interface, I/O peripherals, memory, DSPs, and video controller. Normally, we are able to access the medical system remotely using various methods such as Internet/intranet connections, PC anywhere solutions, Remote Access methods, dial-up connections, or network management station. However, when a system component behaves in an anomalous manner, the system may fail to respond to remote services. For example, the operating system might have halted due to an illegal memory access. Typically, the only recourse available to the user is to power down the system and attempt to restart the system from the powered-down state. Importantly, data that has not been saved from volatile memory to hard disk or non-volatile memory will be permanently lost when the power is removed. Some operating systems display an information screen first before halting; in these systems, the only recourse is to power down the system, or operate a processor-reset button. Current method of diagnosing is to capture the display using video scanner and to send the printout/information for further processing. In any case, it is currently not possible to diagnose or to debug such system live or remotely. To be able to do so is obviously advantageous since much valuable information can only be detected while the system is in its failure state.
