Systems and methods for automated diagnosis and decision support for breast imaging
ActiveUS20050049497A1Ultrasonic/sonic/infrasonic diagnosticsImage enhancementPatient dataDecision taking
CAD (computer-aided diagnosis) systems and applications for breast imaging are provided, which implement methods to automatically extract and analyze features from a collection of patient information (including image data and / or non-image data) of a subject patient, to provide decision support for various aspects of physician workflow including, for example, automated diagnosis of breast cancer other automated decision support functions that enable decision support for, e.g., screening and staging for breast cancer. The CAD systems implement machine-learning techniques that use a set of training data obtained (learned) from a database of labeled patient cases in one or more relevant clinical domains and / or expert interpretations of such data to enable the CAD systems to “learn” to analyze patient data and make proper diagnostic assessments and decisions for assisting physician workflow.

Apparatus and method for cone beam volume computed tomography breast imaging
InactiveUS6987831B2Promote quick completionGuaranteed continuous performanceSurgeryVaccination/ovulation diagnosticsX-rayEntire breast
Cone beam volume CT breast imaging is performed with a gantry frame on which a cone-beam radiation source and a digital area detector are mounted. The patient rests on an ergonomically designed table with a hole or two holes to allow one breast or two breasts to extend through the table such that the gantry frame surrounds that breast. The breast hole is surrounded by a bowl so that the entire breast can be exposed to the cone beam. Spectral and compensation filters are used to improve the characteristics of the beam. A materials library is used to provide x-ray linear attenuation coefficients for various breast tissues and lesions.

A method for performing enhanced ultrasound diagnostic breast imaging includes using first and second compression plates (62,64) configured for receiving and compressing a breast between the same. The breast extends from a chest wall (118) of a patient at a proximate end to a nipple at a distal end. Portions of the breast proximate the nipple and proximate lateral edges of the breast are in non-contact with the second compression plate during breast compression. An ultrasound transducer array (68) moves along a path to scan the breast, the ultrasound transducer array being disposed adjacent a side of the second plate (64) opposite the breast. Image data representative of the breast is acquired as the ultrasound transducer array (68) traverses the path. Acquiring image data includes using electronic beam steering with the ultrasound transducer array to acquire image data in either or both (i) a portion (116) of the breast proximate the chest wall and (ii) a portion of the breast in non-contact with the second plate (122).

A breast imaging system leverages the combined strengths of two-dimensional and three-dimensional imaging to provide a breast cancer screening with improved sensitivity, specificity and patient dosing. A tomosynthesis system supports the acquisition of three-dimensional images at a dosage lower than that used to acquire a two-dimensional image. The low-dose three-dimensional image may be used for mass detection, while the two-dimensional image may be used for calcification detection. Obtaining tomosynthesis data at low dose provides a number of advantages in addition to mass detection including the reduction in scan time and wear and tear on the x-ray tube. Such an arrangement provides a breast cancer screening system with high sensitivity and specificity and reduced patient dosing.
