A system for controlling a hyperthermia treatment device having energy applicators for heating a portion of a patient\s body to attain a predetermined temperature protocol for therapeutic treatment of patient tumors. The system monitors energy application and displays a video presentation of correlative temperature data to an operator who responds by adjusting the energy application to achieve the desired treatment protocol. The system further accumulates a hyperthermia treatment data base, and predetermined temperature protocols for the patient are prepared by comparison with data base protocols for similar tumor conditions. Various figures of merit are also determined and stored in the data base and ongoing treatments are comparerd with the data base to characterize the most effective treatment protocol.

A system for controlling a hyperthermia treatment device of the type which has applicator means for applying energy to attain a predetermined temperature protocol for portions of a patient\s body, the system monitoring said energy application and being capable of adjusting said energy application responsive to operator manipulation, said system comprising: means for sensing temperature of the patient\s body and for providing a temperature signal; computer means having associated instruction and data storage means for interacting with other systems means to perform the energy application, said computer means monitoring said temperature signal and adjusting said energy application responsive to the operator manipulation and having data and instructions defining said predetermined temperature protocol, said computer means utilizing said temperature signal and said protocol defining data and instructions to selectively provide an operator prompt signal indicating the desirability of the operator adjusting said energy application and further providing correlative temperature data associated with said portions of the patient\s body; operator means responsive to the operator manipulation for providing an operator signal to control said energy applicator means via said computer means; and means responsive to said correlative data and said protocol defining data and instructions for displaying a video presentation of said correlative temperature data to the operator, said correlative temperature data displayed in a color coded manner such that preselected colors represent predetermined temperature effectiveness zones of hyperthermia treatment, the operator capable of adjusting said energy application by evaluating said color coded video presentation and providing said operator signal. The system as defined in claim 1 wherein said correlative temperature data comprises selectively at least one of temperature data from (a) a group of said sensing means inside a tumor region, (b) a group of said sensing means outside said tumor region, (c) a mixture of groups from inside and outside said tumor region, (d) a group of said temperature sensing means within said preselected subelement wherein said system is adapted to control the temperature, and (e) a group of said temperature sensing means within and without each said preselected subelement wherein said system is adapted to control the temperature. A method for preparing a predetermined hyperthermia treatment protocol for a tumor in a portion of a patient\s body using a hyperthermia treatment data base defining a plurality of general hyperthermia treatment protocols, comprising the steps of: identifying location, size and type characteristics of said tumor in the patient\s body; mapping data in said hyperthermia treatment data base corresponding to tumor characteristics identified in said patient\s body; and modifying a selected one of said general hyperthermia treatment protocols for said tumor to account for said identified location, size and type characteristics of said tumor in said patient\s body to develop said predetermined hyperthermia treatment protocol. The method as defined in claim 29 wherein said step of comparing arithmetic percentages comprises calculating a difference of said percentages. A method of determining figures of merit for use in a hyperthermia treatment of a tumor in a portion of a patient\s body using an apparatus having a group of temperature sensors disposed in the tumor and another group of temperature sensors disposed in surrounding normal tissue, comprising the steps of; applying energy to heat said portion of the patient\s body; sensing temperatures periodically throughout said hyperthermia treatment for said group of temperature sensors disposed in said tumor and said group in said surrounding normal tissue; storing in storage means said sensed temperatures for each said group of temperature sensors; assigning a temperature threshold zone to each said sensed temperatures; determining percentages for each said group of said sensed temperatures which lie within each said temperature threshold zone; and calculating said figures of merit by comparing selected ones of said determined percentages associated with said temperature threshold zones.
