Radiation Diagnostics Testing/Calibration TRIZ Cases
- Quantitative Pulse Selection for Photon-Counting CT
Segmenting charge events via quantitative pulse selection eliminates pileup and charge sharing errors, improving energy measurement precision.
- Partial Arc Flag Structures for Dynamic Sampling Frequency Adjustment
A radiation imaging system uses discrete flag structures on a partial arc to dynamically adjust sampling frequency based on gantry rotational speed.
- Proximity Sensor Patient Alignment in Nuclear Medicine Imaging
Automated proximity sensors detect patient contours to adjust detector distance, eliminating manual setup errors that degrade image resolution.
- Slidable Radiopaque Marker for Anatomical Orientation
A slidable radiopaque marker repositions on an image receptor to indicate anatomical side orientation, preventing misidentification caused by patient movement.
- X-ray Tube Thermal Load Prediction via Database Matching
Matching procedure parameters against historical data estimates heat generation, preventing unexpected downtime while maintaining image quality.
- Digital Breast Tomosynthesis Phantom with Reverse Staircase Bead Ramps
A phantom uses reverse staircase bead ramps to measure slice sensitivity and spatial resolution in digital breast tomosynthesis systems.
- Radiographic Apparatus Detector Positioning for PET Image Quality
A radiographic apparatus adjusts detector position to center the region of interest within the effective field of view.
