The project ULTRACOV aimed at developing a novel ultrasound scanner to face COVID-19 disease challenges: early diagnosis and following of patients evolution leaded by DASEL get funded by last CDTI call.

This project obtained funding from the las call of the Spanish Institution “CDTI” (July 2020) in a very competitive call for R&D projects to face the health emergency COVID19. ULTRACOV  This development is led by DASEL SL, a Madrid SME based in Arganda del Rey. The Ultrasonic Systems and Technologies Group of the CSIC (GSTU-CSIC) and the Nuclear Physics Group Group of the Complutense University of Madrid (GFN-UCM) will also participate. The participation of the emergency ultrasound service of the Hospital Universitario La Paz guarantees the clinical approach at all stages of the development of the ultrasound system, and will carry out the first trials with patients.

The project duration is 18 months, (starting July 2020) and clinical trials of the prototype are planned to begin in early 2021.

The objective of the ULTRACOV project is the development of an ultrasound scanner oriented to the early detection and monitoring of the COVID-19 disease, specially designed for situations of pandemic and high healthcare pressure. Through interactive artificial intelligence tools that simplify the examination and interpretation of images, and a design oriented to operation in high-risk conditions (easy disinfection, ergonomics, etc.), the aim is to extend lung ultrasound to a greater number of professionals and services, from primary care to intensive care. The impact on the capacity of the healthcare system for the management of COVID-19 patients would be very positive, since it is a very specific tool for evaluating the lung condition at all stages of the disease, including potential chronic problems. in the medium and long term. Furthermore, it would be useful for the diagnosis and management of patients with other lung pathologies, potentially serious in certain groups (pediatric patients, pregnant patients, etc.).

 

 

Andalusia celebrates the third edition of the "Aerospace and Defense Meetings Sevilla-ADM". The congress, to be held from 10 to 13 May 2016, already has registered 408 companies from 24 countries.


This event has become the most important aerospace event in Spain and as a key appointment for the strategic sector of Andalusia.


DASEL and TECNITEST be present at the third edition of the most important BtoB event dedicated to the aviation and space to be held in Seville from 10 to 13 May 2016 sector.


We will be happy to welcome you to our Stand D 16-18, where you can see and check the development of our inspection technology Ultrasonic Phased Array based technology and non-contact inspection system for air.

DASEL announces the release of the new SITAU-MC portable multi-channel system, the ideal solution for field inspection with up to 32 conventional or TOFD transducers. Some of the target application for this system are:

· Tubes / rods inspection in production or service.

· Thick welding inspection with conventional UT and TOFD

· Long-range inspection of pipes and rods.

Main features:

· 16 MHz bandwidth, 40 MHz of sampling frequency and up to 80 dB gain.

· Advanced processing capabilities: EMI noise reduction, Data compression with no peak-loss.

 


 

Adding Conventional Ultrasound channels to Phased-Array equipments is a common practice of ultrasound equipment manufacturers. However, equipments in the market are limited to 4 or 8 channels, which can be not enough for most advanced applications.

DASEL pushes this kind of equipments a step further with the SITAU-MC solution, a powerful system that combines a 128 channel Phased-Array unit with 24 conventional ultrasound channels. Both sub-systems can work in parallel, increasing inspection speed and productivity.

A practical example for this kind of systems can be the inspection of tubes/rods during production, where conventional ultrasound and phased-array are required by normative. Another example is the inspection thick welding, where conventional UT, TOFD and PA are usually combined.

Non destructive evaluation of windmill blades using ultrasound is a challenging task. Microstructure of fiberglass and resin composites (GFRP) introduces dispersive effects on ultrasound waves, which is seen as grain noise and produces high attenuation to ultrasonic signals.

In this work, results of the inspection of a thin GFRP layer (3mm) using phased-array technique are presented. The goal is to detect the presence of broken fibers in the material. A 5MHz array was used, along with a novel C-Scan processing technique, that allows to detect broken fibers with a resolution above 1 mm.
