Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Area of Science:

Medical Informatics
Digital Image Processing
Information Security

Background:

Digital watermarking offers solutions for data security and integrity.
Healthcare data management faces challenges in protecting sensitive information and ensuring authenticity.
Existing methods may not adequately address the specific needs of medical imaging.

Purpose of the Study:

To explore the application of multiple digital watermarking in healthcare.
To present a wavelet-based scheme for medical image security and management.
To protect sensitive patient data and authenticate medical images.

Main Methods:

A wavelet-based multiple watermarking scheme is proposed.
A Region of Interest (ROI) is defined for diagnostic value protection.
Hybrid coding with repetitive embedding of BCH encoded watermarks enhances robustness.

Main Results:

The scheme protects the diagnostic value of the Region of Interest.
Multiple watermarks embed physician signatures, patient data, and retrieval keywords.
The system enhances data robustness and supports secure image archiving and retrieval.

Conclusions:

Multiple digital watermarking is a viable solution for healthcare data management.
The proposed scheme effectively addresses sensitive data protection, authentication, and retrieval.
This approach enhances the security and usability of medical images.
