Radiation Diagnostic Image/Data Processing TRIZ Cases

Air calibration maps detector dose and pixel response in C-arm X-ray imaging to correct gain drift and reduce 3D reconstruction artifacts.

Segmented photon-counting CT isolates coherent scatter from background signals to improve material identification of lesions and objects of interest.

A lifting carriage and traction-guided column precisely align the radiation source, patient table, and detector for accurate imaging.

Depth-based PET detector regions use different energy windows to reject object scatter while retaining detector scatter and improving sensitivity.

Stored facility- and operator-specific positioning data automates medical image capture setup, reducing manual adjustment and workflow burden.

An open-top radiotherapy fixation block supports the lower and side contours of the head and neck to improve reproducibility while reducing patient burden.

Limited-angle multi-spectral X-ray acquisition cuts dose and scan time while enabling material-specific image reconstruction on existing CT systems.

Dose feedback from detection pixels stops radiation and image capture at the right time, avoiding unnecessary frames and power use.

Grouping non-overlapping X-ray source regions cuts mammary ROI extraction time and helps reduce motion artifacts in multi-view imaging.

Non-coplanar source placement with spatial and temporal deviation correction improves digital radiography image clarity and layout flexibility.

CT data itself is used to detect patient breathing phases, enabling phase-correlated imaging without external respiratory devices or re-scans.

A trained AI model predicts radiological images at different contrast agent doses from one input image, reducing multi-image requirements.

A low-resolution full scan plus high-resolution ROI reconstruction cuts 3D imaging time and compute while speeding region inspection.

Continuous EPID cine imaging verifies exit dose during radiation therapy and flags misalignment or anatomy changes before harm occurs.

On-the-fly screening updates defective pixel maps during photon-counting CT scans to catch intermittent pixels and prevent ring artifacts.

Uses medical object entry angle and positioning data to correct preoperative vessel images during surgery and improve alignment with less X-ray exposure.

Two offset X-ray tubes and one detector enable real-time 3D treatment tool positioning without tube rotation or bulky biplane hardware.

RFID on each storage phosphor plate carries exposure parameters to the readout stage, reducing manual entry errors and improving X-ray workflow.

Adjustable primary and secondary collimation enables one-shot or scanning cephalometric imaging with smaller sensors and fewer motion artifacts.

A rigid holder keeps the radiographic plate parallel to implant instruments and the X-ray beam perpendicular for low-distortion intraoperative checks.

Grouping X-ray sources with non-overlapping imaging regions cuts mammography ROI extraction time while preserving multi-angle image quality.

A selectable one-shot or scanning cephalometric X-ray setup cuts sensor cost while limiting motion artifacts and correction needs.

Separating Cherenkov timing from scintillation energy detection improves time and energy information for PET annihilation-position imaging.

A pre-stored correspondence links equivalent phantom thickness with X-ray settings, reducing brightness stabilization time as object attenuation changes.

Shared column lines and staggered pixel timing reduce readout complexity while differential signals improve irradiation detection accuracy for AEC.

This CT imaging case combines air correction, material decomposition, and response-model optimization to reduce noise and artifacts.
