Problem Statement

    • Heavy vehicles with high ground clearance pose a significant risk to road traffic safety, as they may jam during rear collisions, potentially causing catastrophic injuries to the smaller vehicle’s driver and passengers.
    • Rear underrun protection devices (RUPD) protect vehicles from rear collisions, but small vehicle pillars can break during impact, posing a serious threat to drivers and passengers.
    • Conventional RUPDs fail to reduce impact/forces, causing collisions between heavy vehicles and smaller ones, posing a risk to passenger safety.
    • The disclosure aims to address any limitations or issues linked to conventional mechanisms.

Technology

The invention discloses a method of ultrasound

imaging comprising the steps :

  • Exciting a Set of Limited Number of Active Transmit Elements
  • Inducing Diverging Waves
  • Receiving Backscattered Echoes upon ultrasound
  • Translating Electronically the Active Transmit Elements
  • Reconstructing the Received Echoes in a Receive Beamformer
  • Processing to Form an Image by converting the time-delayed echoes into pixel values
  • Displaying the Image

The said translating step may have an overlap between two adjacent sets of active transmit elements

Also, the received echoes data may be from only partial receive aperture.

Further discloses, a system for ultrasound imaging comprising:

  • Transducer Array
  • A Means for Transmit Excitation
  • An electronic translating means
  • A receive beamformer
  • A display device

Said array  formed may be a single array or two dimensional array.

The diverging beam synthetic aperture ultrasound beamforming method offers a less complex ultrasound system by activating only 8 or 16 transducer elements during transmission

Key Features/Value Proposition

Technical Perspective:

  •  A novel technique that combines Diverging Beam with Synthetic Aperture Technique (DB-SAT)
  • Sparse active array without increasing system complexity.

  • The technique of sending diverging waves and using limited number of active elements not only reduces system complexity and cost, but also yields high frame rate involving sparse emission

User Perspective:

  • Reduced complexity in terms of hardware and data handling.
  • Dynamic focusing in both transmit and receive, which leads to better lateral resolution and it is maintained throughout the depth of imaging.
