Abstract

A therapy system comprising a therapy module, e.g. a high-intensity- focused ultrasound transmitter, to perform successive deposits of energy in a target zone, the successive deposits being separated by a cool down period. The therapy system being provided with a thermometry module, e.g. by a magnetic resonance examination system configured for thermometry to measure temperature in a measurement field. A control module regulates the cool down period in dependence of the measured off-focus maximum temperature during the energy deposit preceding the cool down period.

Claims

1. A therapy system comprising a therapy module to perform successive deposits of energy in a target zone, the successive deposits being separated by a cool down period, the therapy system being provided with

a thermometry module to measure temperature in a measurement field and

a control module to regulate cool down period in dependence of

the measured off-focus maximum temperature during the energy deposit preceding the cool down period.

2. A therapy system as claimed in claim 1, wherein the therapy module is a high-intensity ultrasound emitter or a micro-wave emitter.

3. A computer program including instructions to

perform successive deposits of energy in a target zone, the successive deposits being separated by a cool down period

separate the successive deposits being by a cool down period,

measure temperature in a measurement field and

regulate the cool down period on the basis of the measured off-focus maximum temperature during the energy deposit preceding the cool down period.
