Abstract

A method used for planning radiation treatment accessing information that includes calculated doses and calculated dose rates for sub-volumes in a treatment target, and also accessing information that includes values of a measure of the sub-volumes as a function of the calculated doses and the calculated dose rates. A graphical user interface includes a rendering that is based on the calculated doses, the calculated doses rates, and the values of the measure.

Claims22

Dependent claims

A computer system, comprising:

a processor;
a display device coupled to the processor;
and
a memory coupled to the processor, the memory storing instructions that, when executed by the processor, cause the computer system to
access information including calculated doses and calculated dose rates for a plurality of sub-volumes in a volume in a treatment target,
access information including values of a measure of the plurality of sub-volumes as a function of the calculated doses and the calculated dose rates, and
display, via the display device, a graphical user interface (GUI) including, in a single rendering, a representation of the calculated doses, the calculated dose rates, and the values of the measure.

A non-transitory computer-readable storage medium having computer-executable instructions for causing a computer system to perform a method used for planning radiation treatment, the method comprising:

accessing a radiation treatment plan including a number of beams to be directed at and into a volume in a treatment target, directions of the beams, and a range of dose rates for each of the beams, wherein the volume includes a plurality of sub-volumes;
calculating a dose per sub-volume of the plurality of sub-volumes using the number and directions of the beams and the range of dose rates;
calculating a dose rate per sub-volume of the plurality of sub-volumes using the number and directions of the beams and the range of dose rates;
determining, for different levels of dose and different levels of dose rate, a value of a measure of the sub-volumes that are calculated to receive at least a respective level of dose and at least a respective level of dose rate;
and
displaying, on a display device of the computer system, a graphical user interface (GUI) including a rendering of a representation of the calculated dose per sub-volume of the plurality of sub-volumes, the calculated dose rate per sub-volume of the plurality of sub-volumes, and the value of the measure of the sub-volumes that are calculated to receive at least the respective level of dose and at least the respective level of dose rate.

generating a dose-volume histogram (DVH) for a volume in a treatment target, wherein the DVH indicates a measure of the volume that receives a dose;
generating a dose rate-volume histogram (DRVH) for the volume in the treatment target, wherein the DRVH indicates a measure of the volume that receives a dose rate;
and
displaying, on a display device of the computer system, a graphical user interface (GUI) including a combined rendering of the DVH and the DRVH, wherein the combined rendering visualizes a measure of the volume that is calculated to receive a given dose as a function of dose rate and also a measure of the volume that is calculated to receive a given dose rate as a function of dose.
