Abstract
The speed of sound data corresponding to transmission of ultrasound through a cancerous lesion is different than the speed of sound data corresponding to transmission of ultrasound through a benign lesion. The system can assign a coloration to a speed of sound image according to the speed of sound through the tissue as obtained from quantitative transmission ultrasound. The shape indicative of a lesion can be identified through the reflection data with the type of lesion identifiable by the coloration from the speed of sound data.
Claims16
A system for tissue lesion detection and determination, comprising:
- one or more computer readable storage media having instructions stored thereon that, when executed by a processor, direct the processor to:
- determine, for a pixel, whether speed of sound data from a quantitative transmission ultrasound (QTUS) has a speed that satisfies a cyst condition criteria or a solid condition criteria;
- in response to a determination that the speed satisfies the cyst condition criteria, assign a cyst coloration for the pixel;
- in response to a determination that the speed satisfies the solid condition criteria, assign a solid coloration for the pixel;
- and
- in response to a determination that the speed does not satisfy either the cyst condition criteria or the solid condition criteria, assign a default coloration for the pixel.
A method for tissue lesion detection and determination, comprising:
- identifying a region in a reflection image generated from a quantitative transmission ultrasound (QTUS) having a shape indicative of a potential lesion;
- and
- determining whether the potential lesion is likely a cyst or a cancerous lesion using speed of sound image data generated from the QTUS.
One or more computer readable storage media having instructions stored thereon that, when executed by a processor, direct the processor to:
- receive speed of sound image data and reflection image data from a quantitative transmission ultrasound (QTUS);
- perform a thresholding of at least one of the speed of sound image data and the reflection image data to identify pixels corresponding to a potential lesion;
- for at least one pixel of the pixels corresponding to the potential lesion, determine whether the pixel's speed of sound data has a speed that satisfies a cyst condition criteria or a solid condition criteria;
- in response to a determination that the speed satisfies the cyst condition criteria, identify the pixel as having a likelihood of being a cyst;
- and
- in response to a determination that the speed satisfies the solid condition criteria, identify the pixel as having a likelihood of being a solid.
