Arun Presents A Deep Learning Based Alternative to Beamforming Ultrasound Images at IEEE ICASSP 2018

Congrats to Arun on the successful presentation of his research paper entitled “A Deep Learning Based Alternative to Beamforming Ultrasound Images” at IEEE ICASSP 2018 in Calgary, Alberta, Canada. This work is the first to propose deep learning as an alternative to the traditional ultrasound beamforming process and it was implemented for a single plane wave transmission. Check out  our associated conference paper for more details!

Journal Paper Accepted to IEEE TMI

Congratulations to Derek Allman! His paper entitled “Photoacoustic Source Detection and Reflection Artifact Removal Enabled by Deep Learning” was accepted to the IEEE Transactions on Medical Imaging. This paper is expected to appear in the Special Issue on Machine Learning for Image Reconstruction.

This work is the first to use deep convolutional neural networks (CNNs) as an alternative to the photoacoustic beamforming and image reconstruction process. We used simulations to train CNNs to identify sources and reflection artifacts in raw photoacoustic channel data, reformatted the network outputs to usable images that we call CNN-Based images, and transferred these trained networks to operate on experimental data. Multiple parameters were varied during training (e.g., channel noise, number of sources, number of artifacts, sound speed, signal amplitude, transducer model, lateral and axial locations of sources and artifacts, and spacing between sources and artifacts). The classification accuracy of simulation and experimental data  ranged from 96-100% when the channel signal-to-noise ratio was -9 dB or greater and when sources were located in trained locations. Over 99% of the results had submillimeter location accuracy. Our CNN-Based images have high contrast,  no artifacts, and resolution that rivals the traditional photoacoustic image resolution of low-frequency ultrasound probes.

“Directing Light and Learning from Sound to Guide Surgeries”


Just like programming a robot requires meticulous planning, coding, and execution, these same requirements are ever present when designing and controlling the individual optical and acoustic components of photoacoustic imaging systems. Photoacoustic imaging utilizes light and sound to make images by transmitting laser pulses that illuminate regions of interest, which subsequently absorb the light, causing thermal expansion and the generation of sound waves that are detected with conventional ultrasound transducers. The Photoacoustic and Ultrasonic Systems Engineering (PULSE) Lab is developing novel methods that use photoacoustic imaging to guide surgeries with the ultimate goal of eliminating surgical complications caused by injury to important structures – like major blood vessels and nerves – that are otherwise hidden from a surgeon’s immediate view.

In this talk, I will describe our novel light delivery systems that attach to surgical tools in order to direct light toward the surgical site. I will also introduce how we learn from the physics of sound propagation in tissue to develop acoustic beamforming algorithms that improve image quality, using both state-of-the-art deep learning methods and our newly developed spatial coherence theory. These light delivery and acoustic beamforming methods hold promise for robotic tracking tasks, visualization and visual servoing of surgical tool tips, and assessment of relative distances between the surgical tool and nearby critical structures (e.g., major blood vessels and nerves that if injured will cause severe complications, paralysis, or patient death). Impacted surgeries and procedures include neurosurgery, spinal fusion surgery, hysterectomies, and biopsies.


Muyinatu Bell is an Assistant Professor of Electrical and Computer Engineering with a joint appointment in the Biomedical Engineering Department at Johns Hopkins University, where she founded and directs the Photoacoustic and Ultrasonic Systems Engineering (PULSE) Lab. Dr. Bell earned a B.S. degree in Mechanical Engineering (biomedical engineering minor) from Massachusetts Institute of Technology (2006), received a Ph.D. degree in Biomedical Engineering from Duke University (2012), and conducted research abroad as a Whitaker International Fellow at the Institute of Cancer Research and Royal Marsden Hospital in the United Kingdom (2009-2010). Prior to joining the faculty, Dr. Bell completed a postdoctoral fellowship with the Engineering Research Center for Computer-Integrated Surgical Systems and Technology at Johns Hopkins University (2016), where she was co-mentored by faculty in the Computer Science Department and the School of Medicine. Dr. Bell has published over 40 scientific journal articles and conference papers, holds a patent for short-lag spatial coherence beamforming, and is the recipient of numerous awards, grants, and fellowships, including the NIH K99/R00 Pathway to Independence Award (2015), MIT Technology Review’s Innovator Under 35 Award (2016), and the NSF CAREER Award (2018).

JMI Paper Accepted

Congrats to undergraduate student Margaret Allard on the acceptance of her first-author journal paper entitled Feasibility of photoacoustic-guided teleoperated hysterectomies. This paper will appear in the Journal of Medical Imaging (JMI) Special Section on Image-Guided Procedures, Robotic Interventions, and Modeling.

This paper is the first to describe the feasibility of photoacoustic integration with the da Vinci surgical robot to potentially guide minimally invasive hysterectomies and other gynecological surgeries.  To implement photoacoustic imaging, a novel light delivery system was designed and implemented  to surround da Vinci tools. This new light delivery system uniquely enabled the investigations described in the paper, including  the first known analysis of the optimal tool orientations for photoacoustic-guided hysterectomies using a da Vinci scissor tool (which partially blocks the transmitted light in some cases). This work can be extended to other da Vinci tools and laparoscopic instruments with similar tip geometry.

Margaret completed this work through her participation in our NSF Research Experience for Undergraduates in Computational Sensing and Medical Robotics.

Brooke Wins Second Place in Undergrad Poster Competition

Congratulations to PULSE Lab undergraduate student Brooke Stephanian on her 2nd place win in the Optics and Photonics Conference at JHU!

Journal Paper Accepted to IEEE UFFC

Congrats to Arun Nair on the acceptance of his paper entitled “Robust Short-Lag Spatial Coherence Imaging” to the IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control. This paper will appear in the special issue on sparsity driven methods in medical ultrasound.

This work is the first to re-examine the lag summation step of the Short-Lag Spatial Coherence (SLSC) algorithm and achieve additional robustness to coherence outliers through both weighted summation of individual coherence images (i.e., M-weighting) and the application of robust principal component analysis (i.e., Robust SLSC, or R-SLSC). Results show great promise for smoothing out the tissue texture of SLSC images, improving boundary delineation, and enhancing anechoic or hypoechoic target visibility at higher lag values. These improvements could be useful in clinical tasks such as breast cyst visualization, liver vessel tracking, and obese patient imaging.

NIH R00 Grant Awarded

The PULSE Lab received the 2nd phase of Dr. Bell’s NIH K99/R00 award to support our project entitled “Coherence-Based Photoacoustic Image Guidance of Transsphenoidal Surgeries”. This work is motivated by the clinical challenges surrounding the removal of pituitary tumors using the minimally invasive endonasal transsphenoidal approach, which incurs the deadly risk of causing injury to the internal carotid arteries. We propose to eliminate this risk by developing a sophisticated photoacoustic imaging system that visualizes blood vessels located behind bone during the surgical operation. This photoacoustic imaging system will be equipped with our novel coherence-based beamformers and our specialized light delivery systems.
