Abstract
An interstitial laser therapy control system is disclosed. The control system includes a thermistor controller apparatus, a microprocessor, a storage device, at least one input device, a display, an electro-mechanical shutter switch, an electro-mechanical emergency shutoff switch, and an electro-mechanical master power switch. The microprocessor is configured to monitor temperatures detected by one or more thermistors connected to the thermistor controller. Based on the temperatures, the microprocessor determines when treatment has been successful and when application of laser energy needs to be halted. The control system also enables an operator to pause and resume treatment using the input device. The electro-mechanical shutter switch sends a signal to a laser source to close a shutter on the laser. The electro-mechanical emergency stop button causes power to be cut off to the laser source. The electro-mechanical master power switch shuts off power to all components in the interstitial laser therapy apparatus.
