ABSTRACT:
In one embodiment of the invention, a pressure sensor array, data acquisition circuit, and a microprocessor are mounted in a hand held pad. Detection of nodules is achieved by analyzing the dynamic and spatial features of the pressure pattern while the probe pressed to the breast is periodically moved transversely to the ribs. The ribs play a role as an amplifier of the measured effect. The device will be able to objectively detect the presence of lumps in a breast and provide a warning signal. Another embodiment of the invention is a clinical device for imaging the mechanical structure of the examined breast and diagnosing diseases accompanied by changes in the elasticity of breast tissue. This embodiment is made up of an electronically controlled mechanical scanning unit incorporated into a patient support bed. The mechanical scanning unit includes a compression mechanism and positioning system, a local pressure source located opposite a pressure sensor array, and electronic control and interface circuitry. The local pressure source is either a roller moving over the examined breast, or in another embodiment, an indenter which can be moved in all three dimensions and be controlled either automatically by a computer or manually by a mouse. In yet another embodiment, the mechanical scanning system serves as a biopsy guidance means and determines target lesions in the breast to be reached by a biopsy gun or aspiration needle.
