Organ Movement/Changes Detection TRIZ Cases

Distinct acoustic-impedance markers on the imaging table help verify detectability and warn when ultrasound references are unclear.

Projection guides compressed-breast ultrasound scanning to shorten acquisition time, maintain complete coverage, and link images to scan regions.

Target recognition selects the measurement algorithm in an ultrasound image, reducing manual caliper work and improving measurement speed.

Sequential tomosynthesis and ultrasound use a positioning paddle to keep the breast aligned, enabling image fusion without patient repositioning.

Perpendicular tissue imaging and oblique needle scanning are combined to limit side-lobe artifacts while displaying both structures clearly.

Distributed dual-axis and single-axis sensors track shaft motion while the main display shows angles without a large tip sensor.

An AI ultrasound workflow uses LV, LA, RV, and RA strain measurements to detect low-level cardiotoxicity before major heart damage.

A common substrate integrates light emitters with PMUT or CMUT arrays, addressing bulky photoacoustic hardware for compact wearables.

Measured transducer outputs guide backpropagation through a neural wave model to recover speed-of-sound, density, and elasticity.

An MRI-integrated FUS platform releases brain biomarkers across the BBB for genetic analysis without surgical biopsy risks.

Rotary ultrasound scans dense breasts while AI flags lesions, classifies risk, and compares VOI volumes with prior scans.

Conventional arrhythmia localization can miss the source; this catheter combines ultrasound sequencing and biopotential measurements for detailed cardiac mapping.

A conformable ultrasonic array compares tissue echoes before and after compression to map deep-tissue strain and modulus non-invasively.

Pre-operative imaging, skull markers, and a virtual reference frame support real-time internal tracker localization despite brain shift.

An integrated sensor tracks the antenna tip while ultrasound images receive a probe overlay, improving navigation despite therapeutic-energy interference.

Shear wave elastography tracks tissue stiffness during RFA, enabling parameter adjustments that help confirm the planned treatment volume.

Ultrasound supplies breast structure while DOT tracks tissue blood-oxygen changes for non-ionizing tumor screening.

Real-time ultrasound marks needle position before actuation, helping avoid missed lung targets, trauma, and repeat passes.

Navigation planning evaluates instrument bending and anatomy to select reachable deployment locations near the target structure.

Fixed-distance icons keep touch controls separate from ultrasound measurement tools, supporting precise image measurements.

Fault detection lets an ultrasound probe reroute signals from failed cable lanes, preserving image quality and frame rate without duplicating every wire.

Ultrasound signals constrain near-infrared imaging models to account for optode contact and head-shape variation.

Varying ultrasound apertures and extrapolating echo time-of-flight improves resolution while avoiding the signal-to-noise penalty of tiny apertures.
