Systems and methods are disclosed to control the temperature of an RF hyperthermia system with minimum overshoot and to improve safety by, among other things, detecting a defective temperature sensor. Temperature overshoot may be minimized by compensating for the short-term temperature difference between the area being treated and the applicator delivering the RF energy. The RF energy may heat the tissue and then the tissue may transfer heat to the applicator sensor. The system may also adapt to various applicator sizes and shapes by modifying control loop coefficients based on initial probe response.

Hyperthermia treatment systems and methods

A FIFO memory system exhibits data processing capabilities by the inclusion therein of a digital signal processor and an associated dynamic random access memory. The digital signal processor provides significant data processing on the fly while the dynamic random access memory array provides additional buffering capability. Input and output FIFOs are connected to the data and address bussed of the digital signal processor. The control of the digital signal processor is via a host processor connected to the digital signal processor by a serial communication link.

Variable-size first in first out memory with data manipulation

Solid state electronic cameras are made modular so that replacement of inoperative CCD imagers can be done quickly and inexpensively by storing in the camera heads the operating parameters of each of a variety of imagers such as charge coupled device imagers. A camera head with a replacement imager communicates to a resident controller the parameters of the replacement imager selected. Operating parameters such as clock pulse signals may, in addition, be varied as to pulse width and frequency. The parameters are stored in an address set in a look up table in association with imager identifications.
