Foreign Body Detection TRIZ Cases

Segmented central and lateral scintillation detectors improve tumor localization accuracy while a shared handgrip cuts probe cost and complexity.

Multiple 2D X-ray views build a 3D anatomical model for device navigation, reducing CT dependence, radiation exposure, and misdirection.

A 3D magnetometer array creates a magnetic heatmap and overlays it on x-ray images to localize ingested magnets with faster, clearer diagnosis.

A radiographic imaging device trims superimposed frames to keep stent markers oriented consistently.

Time delayed summation technology compensates for reduced X-ray flux from a 2.5 mA source, eliminating thermal overheating and cooling interruptions.

Processing circuitry detects stent marker positions in X-ray images to guide device placement during interventions.

Model geometry predicts position marker locations to minimize offsets from patient movements, ensuring precise three-dimensional reconstruction.

Portable radiation detectors capture radiographic images to detect surgical tools, resolving the contradiction between detection precision and patient burden.

A medical image processing apparatus detects stent markers and associates them with cardiac phases to guide precise device placement.

A knock sensor stopper ring uses a pressing jig to plastically deform into a tube groove, securing the piezoelectric element.

Dual capacitors stabilize output voltage against reset noise and external condition variations in x-ray image sensors.

A light guiding element redirects scintillator light to peripheral photodetectors in wireless radiography systems.

Scattered ray beams replace external surrogates and metal markers, resolving tracking uncertainty and surgical risks.

A radiotherapy tracking apparatus coordinates digitally reconstructed radiographic images with X-ray fluoroscopic frames to calculate specific region positions.
