Radiation Diagnostic Device Control TRIZ Cases

Scout-image and protocol-driven ML selects the right AEC sensors automatically to reduce X-ray over-exposure from manual setup errors.

Spiral fan-beam scanning with controlled rotation speed reduces distortion, avoids shoulder contact, and captures complete projection data.

Patient authentication data is used to grant tablet editing authority only for the correct imaging modality, preventing misidentification during exams.

Pose deviation feedback aligns independently controlled X-ray emitters and detectors to improve image coverage and eliminate bright edges.

Real-time chest or abdomen visualization guides patient breathing and flags deviations to reduce scan motion and improve image quality.

Workflow cameras verify mirror placement before scanning to secure line-of-sight, signal quality, and patient positioning in bore imaging.

A 3D scout scan and AI landmark detection set CT gantry tilt automatically to protect the eye lenses without slowing head scan workflow.

Discrete CT scans at multiple height positions replace helical motion to widen upright imaging range while reducing body movement and control complexity.

Sorted past irradiation angles on a compact display let operators choose the next X-ray view faster without switching through image sets.

A pre-captured X-ray shown on a mobile terminal guides femur condyle alignment, cutting repeat adjustments, dose, and imaging time.

A single orientation sensor compares device pose with the imaging protocol to confirm radiography readiness while reducing system size and complexity.

Pressure-triggered stop control in an X-ray temple supporter prevents excessive head force and reduces pain during examinee positioning.

Elastic deformation sensing stops the X-ray head positioning guide at a reference pressure to prevent temple support pain and pressure buildup.

Projected floor guidance and timed room dimming help subjects follow radiography positioning cues while reducing operator burden.

A mechanically adjustable X-ray emitter changes anode orientation to deliver application-specific beam characteristics in one C-arm system.

Selective pixel disconnection captures local coincidence events in CT detectors, cutting crosstalk, parasitic capacitance, and power use.

Intermittent still and dynamic image capture manages cumulative radiation dose while preserving positioning checks and image quality.

Selective switching disconnects adjacent pixel signals during coincidence detection, cutting parasitic capacitance, power use, and CT image errors.

Pulsed high-energy and continuous low-energy fluoroscopy frames enable dual-energy subtraction with shorter exposure and better pulmonary tissue contrast.

Alternating two X-ray tubes with one detector enables 3D position imaging with lower dose, stable time-axis image quality, and better device visibility.

Adaptive CT scan delays from an X-ray tube thermal model cut protocol time while keeping tube components within thermal limits.

Multiple cathode electron sources shift the CT focal spot without changing beam trajectory, reducing blur while limiting anode overheating.
