Existing breast screening and diagnostic technologies have clinical limitations.

  • There is a need for higher sensitivity for the detection of breast cancer on screening exams (mammograms are suboptimal, especially in patients with dense breast composition).
  • Women need a radiation-free technology that does not expose breast tissue to radiation, further increasing cancer risk
  • Higher specificity (lower non-cancer recall rate)  is required to manage benign abnormalities and decrease the number of negative biopsies performed
  • The breast screening process is uncomfortable/painful for women
  • Improved efficiency of physician and technologist time is needed (reimbursements are low and exams are time consuming).


Understanding transmission ultrasound.

The QT Scanner is a fixed, mechanical scanner used to evaluate the breast without the use of ionizing radiation or painful compression associated with mammography.  With the QT Scanner, the patient lies comfortably on a table which contains an opening through which the breast is placed in a warm water bath and gently immobilized using a magnetic retention pad to a magnetic rod. Surrounding the warm water bath is an ultrasound armature that rotates 360 degrees around the breast to produce 3D images. Handheld ultrasound uses reflection data of sound waves to produce images, but the QT Scanner differs in that it utilizes reflection and transmission data from sound waves, providing a significant increase in diagnostic information using the speed of sound characteristics of the breast and generating a true 3D rendering of the breast tissue. The scanner provides sub-millimeter image resolution enabling identification of normal and abnormal breast structures and the accurate depiction of the precise shape and location of findings. The technology uniquely quantifies breast density using transmission information to further personalize a patient’s management recommendations. Surface-to-volume ratios and volumetric doubling time growth rate characteristics can be calculated to determine significance of lesions and improve specificity of the ultrasound. The scanner will also be capable of identifying microcalcifications, necessary in the diagnosis of early breast cancer.

The QT Ultrasound scanner changes the paradigm of breast imaging.

  • A QT Scan uses no ionizing radiation and provides highly reproducible results.
  • The QT Scanner is a high-resolution imaging method for breasts with true computerized 3D tomographic images.
  • The mechanics of the QT scanner provide precise measurement, location, and excellent contrast.
  • Image processing provides information on tissue characteristics, such as “stiffness” due to the availability of speed of sound measurements and reflection data from the breast tissue.
  • The QT Scanner provides information on tissue doubling times not possible with other non-ionizing imaging procedures, allowing for improved specificity of lesions detected and overall improved management of benign and malignant breast masses.
  • This technology has potentially improved PPV (positive predictive value) and NPV (negative predictive value) compared to other imaging modalities.
  • The scan is automated and an efficient imaging system providing savings in time and streamlines workflow which will improve interpretation efficiency and cost reimbursement.
  • The QT Scanner offers a compression-free examination of breasts, providing a painless procedure for women.

The clearest picture is our greatest asset.

Dense breasts are common. Changes to breast tissue due to aging is normal. Even cysts are typical. When we have images that show clear information about breast tissue, we can identify what is benign, and what’s problematic. Our technology is moving us closer to understanding the difference, and our clinical trials are designed to confirm how this new technology can make unnecessary callbacks a thing of the past.
