We Are Cephasonics Ultrasound

Reimagining Ultrasound

Enabling a revolution in ultrasound-based healthcare support with Xavier, AI and a new approach to designing ultrasound systems

Ultrasound software platforms


Ultrasound Today• Visual• Safe for long-term use• Requires an expert to interpret• Passive • Lots of unused information• Huge unrealized potential


Anyone know what this is and what it means?


Or this?


What We Really Want From Ultrasound…

Rather than displaying vague grey images, we need the ability to collect and use data in real time:

MeasureAugment medical procedures

Enhance and speed up diagnosis

Measure key metrics in the body

Characterize tissue

Track changes in existing conditions

Recognize, measure & interpret


Let’s Imagine a Future ofData-Driven Ultrasound


Ultrasound Augmenting a Surgical Procedure

What if ultrasound systems could assist a surgeon by identifying, locating and measuring specific structures at and around the point of surgery.


Ultrasound Measuring And Tracking Disease Status

What if an ultrasound system could quickly track and measure the status of a patient’s condition instantly in the doctors office, an outpatient clinic or even at home.


Ultrasound For Immediate Action in the ICR/ER

What if an ultrasound system could be used to assist in emergency & trauma situations to assess the critical condition of a patient.


Today:• We dumb down the data to create an image• Lots of usable information gets thrown away• Can’t process all the data in real time• Too hard to use – experts required• Can’t recognize, measure or interpret what it sees

We Can’t Get There From Here…(without changing how we approach the problem)


#1 – Focus on the Data

Think of ultrasound not as just imaging, but as data collection and analysis!

Data-driven Ultrasound

Tomorrow:


#1 – Focus on the Data

Everyone talks about AI and ultrasound but, AI is only as good as the data we can collect and use!

Tomorrow:


#2 – Do It In Real Time

Data is only good if you can get it to where you need it!

Tomorrow:


#3 – Move the math closer to the source

Tomorrow:


• Do the processing in the ultrasound engine

• Custom designed FPGAs

• Integrate Xavier directly in the data stream

• Dynamically load software into FPGAs and Xavier

• Client-server model for the software

• Move AI processing to Xavier in the engine
