The Sonoprobe Medical Device
SonoProbe is a diagnostic and therapeutic treatment probe percutaneously introduced in a tumor under local anaesthesia. Slightly larger than a biospy needle, the SonoProbe is composed of dozens of miniaturized ultrasound transducers that are able to emit high intensity ultrasound waves for therapy.
Treatments with the SonoProbe are continuously monitored and controlled by software that interfaces with an MR imaging system, performs treatment simulations, and executes treatments with real-time temperature feedback control.
In the figure below, the color code corresponds to heating of brain tissue around the probe. On this figure, the probe is artificially represented for clarity, as the probe is nearly invisible on the MR images.
This innovation and development are currently in pre-clinical testing, which will soon allow for an application in humans for the treatment of brain tumors.
