Imaging thermometry

An imaging method for monitoring a temperature of a volume or region of interest, comprising:

• generating thermometry image data based on baseline computed tomography image data and subsequently acquired intermittent computed tomography image data, wherein the thermometry image data includes voxels or pixels indicating a change in the temperature in the volume or region of interest, wherein the volume or region of interest is heated between the acquisition of the baseline and the acquisition of the intermittent computed tomography image data, and a Wronskian change detector algorithm generates the thermometry image data;
• and
• generating a thermal map for image data voxels or pixels representing the volume or region of interest based on the thermometry image data and a predetermined change in voxel or pixel value to temperature lookup table.

A non-transitory computer-readable medium having one or more executable instructions stored thereon which, when executed by at least one processor, cause the at least one processor to perform an imaging method for monitoring a temperature of a volume or region of interest, the method comprising:

• generating thermometry image data based on baseline computed tomography image data and subsequently acquired intermittent computed tomography image data, wherein the thermometry image data includes voxels or pixels indicating a change in a temperature in the volume or region of interest, wherein the volume or region of interest is heated between the acquisition of the baseline and the acquisition of the intermittent computed tomography image data, and wherein a Wronskian change detector algorithm generates the thermometry image data;
• and
• generating and displaying a thermal map for image data voxels or pixels representing the volume or region of interest during an interventional procedure based on the thermometry image data and a predetermined change in voxel or pixel value to temperature lookup table.
