Title: High Resolution Stimulations and Recording of The Peripheral and Central Nervous System for Sensory Feedback in Prosthetic Limbs

 

Abstract:

As prosthetic limbs that are neurally integrated into the nervous system are developed, it becomes necessary to invent new ways to record activity from, and to communicate sensory data to the nervous system.  This is particularly true for upper limb prosthetic devices, where the location of recording activity and communicating sensory data happens in the cortex.  Hence, this talk will summarize some of the work that has been done to develop implantable neural recording and stimulation devices.  It will conclude with some brand new sensory feedback experimental results.

Title: Synthetic aperture ultrasound imaging and its real-time implementation

 

Abstract:

Synthetic aperture ultrasound imaging (SAUI) offers many advantages compared to traditional ultrasound imaging. SAUI can attain a higher frame rate, better resolution and contrast and it possible to perform quantitative vector flow imaging. The tutorial will explain about problems and solutions for making SA imaging with a good penetration depth and high quality. I will also be shown that the theoretical advantages translate into the clinic, and it will be described how to make flow imaging. The Achilles heal of SAUI is the large amount of calculations to be performed in such a system, and this currently precludes the introduction of commercial systems. A step to solving this is the experimental Synthetic Aperture Real-time Ultrasound System (SARUS) developed a Center for fast Ultrasound Imaging. It can perform real time SA imaging and storage of RF channel data for multiple seconds. The design principles of the scanner will be described. SARUS sample and process 1024 channel simultaneously giving data rates of 140 Gbytes/s. Using 320 large FPGAs the full system can perform 25,600 billion multiplications/s. The design of the parametric beamformer will be described as well as the principles for controlling such a large system through a simple Matlab interface. The system is capable of real time synthetic aperture imaging.

Title: CMOS-circuits/samples interface: improvements by nanotechnology in label-free diagnostics

 

Abstract:

Personalized therapy requires accurate and frequent monitoring of the metabolic response by treated patients. In case of high risk side effects, e.g. therapies with interfering anti-cancer molecule cocktails, direct monitoring of the patient's drugs metabolism is essential as the metabolic pathways efficacy is highly variable on a patient-by-patient basis. Currently, there are no fully mature point-of-care bio-sensing systems for drugs metabolism monitoring directly in blood. To develop low-cost Point-of-care technology, the development of dedicated IC circuits is highly required. On the same time, there are not technologies for on-line monitoring in real-time of stem cell cultures. Many details of stem cells biology are still missing and new platform for non-invasive monitoring in real-time during cells proliferation, switching and differentiation are definitely required. The aim of the present talk is to show possible directions to develop systems for real-time monitoring to be used in personalized therapy or in regenerative medicine. Enzymes are the considered probe molecules as they are key proteins directly involved in cells metabolism. Sensitivity improvement is ensured by means of enzyme integration onto electrodes structured by using carbon nanotubes. The physics of this improvement is investigated meanwhile recent data on metabolites monitoring are presented. Finally, a VLSI design perspective is traced toward new biochip architectures for personalized therapy or regenerative medicine. Different CMOS designs are compared toward IC biochip developments especially focused to distributed sensors and their integration in sensor networks.
