1. A method for implementing and monitoring a thermal ablation procedure comprising:
- conducting a thermal ablation procedure by directing high intensity focused ultrasound at an ultrasound focus having an elongated focus shape encompassing tissue to be ablated in a subject;
for an image composed of voxels representing a region of the subject encompassing said ultrasound focus, setting, in a computer, a cuboid shape of each of said voxels, as adapted voxels, dependent on said focus shape; and
in said computer, generating said image of said region of the subject by composing said image of said adapted voxels, and including a representation of said ultrasound focus, with said cuboid shape, in said image composed of said adapted voxels.

Abstract
A device for implementation and monitoring of thermal ablation has a device for generation of high intensity ultrasound and a magnetic resonance system for generation of examination images composed of voxels that contain temperature information. The geometry of the voxels is adapted to the shape of the ultrasound focus.

9. A method for magnetic resonance monitoring of an ablation procedure conducted at a subject using high intensity focused ultrasound directed at the subject in an ultrasound focus having an elongated focus shape, comprising the steps of:
-
acquiring magnetic resonance data from the subject during said ablation procedure, said magnetic resonance data including temperature information of tissue affected by said ablation procedure; for a magnetic resonance image from said magnetic resonance data composed of voxels, setting, in a computer, a cuboid shape of each of said voxels, as adapted voxels, dependent on said focus shape and in said computer, generating said magnetic resonance image of said region of the subject by composing said image of said adapted voxels, and including a representation of said ultrasound focus, with said cuboid shape, in said image composed of said adapted voxels. - View Dependent Claims (10, 11, 12, 13, 14, 15)
