Ultrasonic/Sonic/Infrasonic Diagnostics TRIZ Cases

Vertically offset bond lines disrupt liquid paths in an ultrasonic probe, reducing short-circuit and corrosion risks.

A fold-open housing tray stores extra-length cables, reducing catches and damage while the ultrasound apparatus moves between rooms.

Missing patient fields in worklist orders can cause mix-ups; local editing and volatile-to-nonvolatile storage improve record reliability.

A flux-passing structure lets the metal inner housing dissipate transducer heat while limiting eddy-current interference with magnetic sensing.

Pixel thresholds, peak tracking, and change analysis automatically identify contrast-agent arrival, reducing manual ultrasound review time.

Profile-matched surfaces let the compensating member approach the transducer path, reducing coupling-fluid volume and probe weight.

A reusable modular speculum combines imaging and sensors to document anatomy and create a portable digital twin for clinical assessment.

A recessed portion between the waveguide and condensation part reduces acoustic-impedance mismatch and ultrasonic-wave loss during transmission.

A gelatinous acoustic medium holds its shape, reducing air bubbles and reverberation while improving needle-path alignment in ultrasound imaging.

Buffer elements and sealing material keep ultrasound array air kerfs unfilled during catheter fabrication without increasing the imaging component's footprint.

A structured composite backing attenuates backside echoes, helping compact intraoral probes image gums and tooth surfaces with improved sensitivity.

A torque protection mechanism limits probe-tip rotation and flexing pressure to help prevent tissue injury during transesophageal procedures.

Frequent connector wear can raise patient risk and maintenance costs; a swappable fiber component supports cleaning and replacement during procedures.

Optical fiber sensing distinguishes arteries from veins using wavelength shifts and vessel-state signals, reducing wrong-vessel insertion risk.

Electromagnetic sensors align HMD and instrument positions with the ultrasound image plane, supporting sterile, continuous procedural guidance.

Sensor-based orientation feedback shows transducer assembly angles on the ultrasound display, helping operators verify alignment during probe removal.

An ultrasonic holder combines a probe with detachable laser markers or needles, reducing instrument changes during surgical positioning and marking.

Position and orientation sensors in probes and delivery catheters automate multiplanar reformation, reducing manual setup and fluoroscopy reliance.

Real-time ultrasound, 3D prostate models, and electromagnetic sensing link puncture holes to targets, reducing repeat punctures and sampling time.

Backward ultrasound is scattered by porous ceramic particles while conductive filler carries heat from the piezoelectric layer to a heat exhaust block.

ECG-synchronized pulse timing separates ablation current from ultrasound capture, reducing image noise during real-time myocardial monitoring.

Magnetic catheter nodes map the mitral annulus and deployment point, improving device position and orientation during intravascular procedures.

A stabilizer, needle-guide holder, and single-use pad steady an ultrasound probe for hands-free vascular access imaging and insertion.

Pairing skin-mounted IMUs with ultrasound bone tracking resolves the accuracy-versus-noninvasiveness tradeoff in joint motion measurement.

An adjustable clamp and segmented handle improve ultrasound control while reducing grip strain, needle-stick exposure, and cleaning complexity.

A detachable probe and actuator assembly provides four degrees of freedom for accurate positioning in MRI-ultrasound fusion and MR scanner rooms.

A centralized timestamp pulse synchronizes signals from different medical modalities, reducing control-interface complexity during data acquisition.

A stiff sheath keeps tissue stable as an imaging probe moves, helping limit bubbles and improve image quality during surgery.

A cover plate and peripheral wall hold solid coupling gel against the ultrasonic head, simplifying cleaning and assembly.

Automated IVUS measurements map lumen dimensions along vessel position, reducing manual calculations and shortening assessment time.
