[Holographic methods in medical diagnostics (author's transl)]

Area of Science:

• Physics
• Medical Imaging
• Optics

Background:

• Holography principles are fundamental to advanced imaging.
• X-ray imaging is crucial for non-destructive analysis and medical diagnostics.
• Current 3-D X-ray imaging methods have limitations.

Purpose of the Study:

• To describe the principle of holography.
• To discuss applications in 3-D X-ray imaging.
• To introduce two novel holographic methods for 3-D image display and tomogram synthesis of X-ray objects.

Main Methods:

• Method 1: Synthetic hologram creation from multiple conventional radiographs.
• Method 2: Coded image formation using an array of X-ray sources, decoded via holographic filtering for tomogram synthesis.

Main Results:

• Demonstration of initial experimental results for both holographic methods.
• Validation of the feasibility of synthesizing tomograms using holographic filtering.
• Successful display of 3-D images from X-ray data.

Conclusions:

• The presented holographic methods show promise for advanced 3-D X-ray imaging.
• These techniques can synthesize tomograms and display 3-D structures.
• Further experimental validation is ongoing.
