    摘要: There is provided a method of determining a measure of the cardiac output, CO, of a patient, the method comprising obtaining measurements of one or more physiological characteristics of the patient, the physiological characteristics including at least the heart rate, HR, of the patient, the systolic blood pressure, S, of the patient and the diastolic blood pressure, D, of the patient; and processing the measurements to determine a measure of the cardiac output of the patient; wherein the measure of the cardiac output of the patient is derived using the relationship CO = K 1 ⁡ ( HR ⁢ S - D S + D ) , CO = K 2 ⁢ HR ⁡ ( S - D ) ⁢ ( PTT ) 2 , and ⁢ / ⁢ or ⁢ CO = K 2 ⁢ HR ⁡ ( S - D ) ⁢ ( PAT - PEP ) 2 where K1 and K2 are patient-specific calibration factors, PAT is the pulse arrival time, PEP is the pre-ejection period and PTT is the pulse transit time, the time taken for a pulse wave to travel between two points in the body of the patient.

    摘要: Provided are methods and devices that pertain to the acquisition of data related to breast vascularity associated with breast cancer, use of data, or both, that are associated with the generation of sounds, including Korotkoff sounds, within a breast. The present methods and devices overcome the inherent limitations associated with x-ray absorption (upon which mammography relies) by the breast tissue of younger women, and may also be used to augment traditional single-parameter (visual) analysis of a breast through the use of a new parameter—sound. Also disclosed are databases comprising breast sounds that may be used to provide a more complete assessment of a patient's breast, either alone or in combination with the traditional visual parameter.

    摘要: Provided are systems using compression devices for a mammography unit, and methods of using the same. The instant mammography units can comprise at least one x-ray transparent inflatable chamber. When fluid is introduced into the chamber, at least one surface of the chamber expands, and the breast and its vasculature are compressed. Fluid may also be released from the chamber, and as the chamber deflates, blood flow to the breast is restored, producing Korotkoff sounds. Sound data may be obtained with respect to both of a patient's breasts, and the sound data from a patient's first breast may be compared with the data obtained from the contralateral breast. The detected sounds, the comparison data, or both may assist a radiologist in identifying regions of interest on a mammogram, and to enhance a computer-assisted detection (CAD) process and a database of mammography images.
