Abstract: Devices, systems, and techniques are disclosed for planning, updating, and delivering electric field therapy. In one example, a system comprises processing circuitry configured to receive a request to deliver alternating electric field (AEF) therapy and determine therapy parameter values that define the AEF therapy, wherein the AEF therapy comprises delivery of a first electric field and a second electric field. The processing circuitry may also be configured to control an implantable medical device to deliver the first electric field from a first electrode combination of implanted electrodes and control the implantable medical device to deliver, alternating with the first electric field, the second electric field from a second electrode combination of implanted electrodes different than the first electrode combination.

Abstract: A method may include, receiving, by a computer system, indications of a plurality of attributes associated with applicable individuals, wherein each respective one of the applicable individuals is a member of a human population and is a potential user of a medical therapy. The method may further include, for each respective attribute of the plurality of attributes, receiving, by the computer system, a respective indication of a prevalence of the respective attribute, and estimating, by the computer system, based on the indications of the prevalence of the respective attributes, a number of applicable individuals. The method may also include outputting, by the computer system, the estimate of the number of the applicable individuals.
