Handling Using Diaphragms/Collimeters TRIZ Cases

Electromagnetic actuation rotates the shutter frame while optical sensors detect position for precise state control.

Interface module connects X-ray collimators via rotatable adjustment plates and pivoting swivel elements for secure attachment.

Replacing photomultiplier tubes with a charge coupled device eliminates temperature drift and magnetic sensitivity while maintaining high spatial resolution.

A collimator with a curved slit profile shapes radiation rays into a rectangular projection on the detector.

A system acquires images during radiation delivery to determine collimator leaf positions and present error notifications.

Vertically offset leaf layers in a multi-layer collimation system improve aperture resolution beyond single-layer limits.

Multi-aperture collimator segments orthovoltage x-rays into diverging minibeams merging at a controlled depth to confine dose and spare proximal tissues.

Opposing actuators drive a radiopaque shuttle to segment beam exposure, resolving the trade-off between shutter speed and device complexity.

Shaped multileaf collimator tips form stable conical apertures, eliminating double passes and collision hazards in stereotactic radiosurgery.

A helical spin-roll beam chopper modulates X-ray beams through rotating cylindrical apertures.

A radiation detection system uses a photosensor with linear temperature response to stabilize output signals.

An adaptive multi-pinhole collimator maximizes packing density and minimizes truncation to enhance detection efficiency.
