Mammography TRIZ Cases
- Mammography Arm Layout to Reduce Rotational Moment Load
Balancing the drive and restriction mechanisms across the arm center line cuts rotational moment and drive load in mammography equipment.
- X-Ray Tube Filament Current Control for Resistance Drift
Resistance feedback updates filament current as x-ray tube wear increases resistance, stabilizing output and reducing recalibration.
- Multi-Source X-Ray Imaging with Beam Stop Arrays for Scatter Correction
Beam stop arrays and multi-source X-ray capture reduce scatter artifacts and geometric errors while shortening scan time and preserving image quality.
- Dual-Energy Contrast Imaging With Artifact Region Suppression
Low- and high-energy image differencing identifies artifact regions and suppresses obscuration, making contrast medium clearer in radiographic images.
- Adaptive X-Ray Tube Filament Current Control for Resistance Drift
As filament wear raises resistance, feedback adjusts current at each tube-voltage station to maintain consistent radiation output.
- Polychromatic X-ray Analyzer Imaging Synchronization
Synchronizes detector movement with object rotation to acquire rocking curves across all energies simultaneously.
- Mammography De-scattering Algorithm for Dosage Reduction
Computational de-scattering processing replaces physical anti-scatter grids in mammography systems to remove X-ray scatter from images.
- X-ray Sensor Converter for Continuous PPV Monitoring
Scintillation crystal converts X-ray energy to light signals detected by a photo diode, enabling continuous measurement of Practical Peak Voltage.
- Digitally Switchable X-Ray Source for Material Differentiation
Periodic voltage switching differentiates material contrast in x-ray imaging, resolving the trade-off between measurement precision and device complexity.
- X-ray Apparatus Error Detection via Auto Exposure Control Analysis
An X-ray apparatus detects density abnormalities in pre-shot images using automated pixel value analysis to trigger alarms before main exposure.
- Contrast Agent Reference Insert for Breast Imaging Quantification
Thin film reference insert containing known contrast agent concentrations enables simultaneous imaging with the breast for precise quantification.
- Articulated Touch Screen for Mammography Patient Guidance
An articulated touch screen user interface positions to face the patient during mammography procedures.
- Radiation Imaging Cassette Dynamic Mode Switching
A radiation imaging cassette detects storage failures and establishes external communication to resolve capacity limits.
- Contrast Imaging Control Apparatus for Dynamic Timing Adjustment
A control apparatus captures low and high energy images to generate a difference image for contrast analysis.
- Auger Plate Graphite Fiber X-ray Phase Contrast Imaging
Graphite fiber Auger plate converts x-ray photons into electron cascades, resolving low detection efficiency and high tissue dose in phase contrast imaging.
- X-ray Imaging System with Dual Detectors for 3D Structure Analysis
An x-ray imaging system uses primary and secondary detectors to capture transmission and scattered radiation simultaneously.
