Traditional imaging tools like mammography and ultrasound have long dominated the diagnostic space, but US20120065539A1 challenges their limitations with a unique, affordable, and non-radiative alternative.

The driving force behind this invention is the need for early detection methods that are not only accurate but also accessible and comfortable for patients. With a growing emphasis on preventive healthcare, technologies like the one proposed in US20120065539A1 are essential in bridging gaps in diagnostic coverage—especially in low-resource settings.

Technical Field

The technology covered under US20120065539A1 is rooted in biomedical impedance analysis. Specifically, it applies to detecting anomalies in breast tissue by measuring how electrical signals interact with different tissue types. This patent not only focuses on breast masses but also hints at broader medical potential. Similar impedance-based mechanisms could be adapted to assess organs like the liver or lungs, extending its utility across multiple diagnostic platforms.

Summary of the Invention

At its core, US20120065539A1 outlines a device and method capable of detecting variations in electrical impedance caused by abnormalities such as tumors or cysts. The system sends a low-energy electrical signal through the breast tissue and records how the signal is altered. These changes are then compared to known impedance profiles, allowing the system to identify potential masses.

Objectives of the Invention:

Offer a non-invasive, pain-free alternative to mammography
Improve diagnostic accuracy using real-time impedance mapping
Enable point-of-care testing in both clinical and remote environments

Detailed Description

The patent goes into meticulous detail about the construction and functionality of the system. Below is a breakdown of the key components and how they work together to perform breast-mass detection.

System Components

Component	Functionality
Signal Generator	Produces electrical signals at various frequencies
Source Electrodes	Apply signals to the tissue
Receiving Electrodes	Capture altered signals from the tissue
Processing Unit	Analyzes signal alterations using software algorithms
Display Interface	Presents diagnostic feedback to the user through visual or audible cues

The electrodes can be arranged in various configurations depending on the area to be examined. The patent discusses both fixed and dynamic placements, ensuring flexibility during use.

Signal Characteristics

Signals used in this system vary in frequency and waveform. For effective tissue discrimination:

Low-frequency signals penetrate deeper tissues
High-frequency signals enhance surface resolution

Together, these enable the detection of both superficial and embedded masses.

Data Analysis and Interpretation

The collected signals are subjected to digital signal processing (DSP), which helps extract meaningful patterns from the noise. Algorithms compare this data against a database of known impedance signatures. The outcome can include:

Identification of mass location
Classification as benign or suspicious
Recommendations for further testing

Methodology

The procedural flow of US20120065539A1’s method is as follows:

Electrode Placement: Electrodes are applied to the breast, ensuring optimal contact.
Signal Emission: The generator sends a predefined range of frequencies through the tissue.
Signal Reception: Receiving electrodes collect the altered waveforms.
Digital Analysis: The system evaluates amplitude, phase shifts, and waveform patterns.
Comparison: The results are compared with stored impedance data of healthy and abnormal tissues.
Diagnosis Output: The final analysis is provided via display or external connection to diagnostic tools.

This step-by-step process ensures accuracy and reproducibility, making the system suitable for both clinical and home settings.
