Microwave imaging for biomedical applications, especially for early diagnosis of breast cancer, has attracted increasing interest in last several decades. This fact is due to the high contrast between the dielectric properties of the normal and malignant breast tissues at microwave frequencies, ranging from high megahertz to low gigahertz. The available range of dielectric properties for different soft tissue can provide important functional information about tissue health. Nonetheless, one of the limiting weaknesses of microwave imaging is that unlike conventional modalities such as X-ray CT or MRI, it inherently cannot provide high-resolution images. The conventional modalities can produce highly resolved anatomical information, but often cannot provide the functional information required for diagnoses.
In order to improve the specificity of MR imaging, Dartmouth inventors have developed a system and method whereby the anatomical spatial information from the MR is fed into the microwave imaging algorithm to recover accurate dielectric property maps of suspicious regions. This will provide a richer data set for the clinician to draw from in making diagnoses.
These technologies are claimed in the published PCT Application No. PCT/US11/24216. We are seeking an industrial partner interested in their licensing and commercialization. (J549)
