This paper gives a brief introduction into dose response relationships for early and late radiation responses and tumor control.

Did you know?
WebThis means that when you have dose enough to achieve 95% tumour control, that same dose might only result in an NTCP of 10% (again, it's relative, but the NTCP is usually always lower than the TCP for the same dose). And the difference between these two curves (at some given point on the curve, usually 50% probability) is the therapeutic ratio. WebTransmission Control Protocol (TCP) is a standard that defines how to establish and maintain a network conversation by which applications can exchange data. TCP works …
WebThe browser-viewable page connects to the WS server using JS. The JS-based page sends a command to the server, including to which bridge it must go. The server forwards the command to the bridge. The bridge opens a TCP/IP socket and interacts with it (sends a message, gets a response).
