Mimics Innovation Course 2017

Materialise provided a Mimics Innovation Course on Soft Tissue.

This training was very informative and well-presented with all soft tissue samples, text book and datasets.

I used 3-Matic for the first time, and got confidence about many things about design and meshing. We could also discuss our own projects and could ask possible options of Mimics Innovation Suite.

Learning about the news about scripting possibilities to automate the workflow, and ADam (Materialise Anatomical Data Mining) for shape optimisation was encouraging.

Thank you for sharing your knowledge with us, Karen and Inés.

Thank you for the great help of Job.

Vivitro Pulse Duplicator Training in Protomed Labs

http://www.protomedlabs.com

It was really a great experience at  Protomed Labs in Aix-Marseille University. I really enjoyed learning about hydrodynamic testing requirements, Vivitro Pulse Duplicator, its calibration, flow testing, heart valve testing, and at the same time  practicing.

Thanks to Prof. Kerem Pekkan for suggesting this training for Ece Tutsak and me.

I would like to express my sincere thanks and gratitude to  Karim Mouneimne and Vincent Garitey for all the kind care they took, regarding the training, sharing their expertise to us, the  detail notes, all the answers whenever required etc. in Protomed Labs.

I hopefully will be able to implement it further into my field.  This got me inspired and ready to go!

Advances in Cardiac Imaging

While cardiac magnetic resonance imaging (MRI) is considered an excellent imaging modality for the heart, offering highly detailed soft tissue anatomical imaging as well as functional assessments, it only makes up about 5 percent of all MRI scans in the United States. This is in part due to the expense, time involved and the complexity in completing these scans and reading them. There were two software innovations that may help increase the use of cardiac MRI by reducing its complexity.

At RSNA 2015, Arterys introduced a package of advanced cardiac MRI visualization and quantification software that automates a lot of the processes involved. It also uses a cloud-based platform that allows access to a large amount of computing power needed to process cardiac cine functional data in real time. The software includes 4-D Flow and 2-D phase contrast workflows, and cardiac function measurements. The software is the first clinically available cardiovascular solution that delivers cloud-based, real-time processing of images with resolutions previously unattainable. The company gained U.S. Food and Drug Administration (FDA) 510(k) clearance in November 2016 and showed several new advancements at RSNA 2016. Arterys is partnering with GE Healthcare to introduce the software on the Signa MRI systems under the GE name of ViosWorks. However, Arterys said it has aspirations to be a software OEM for several MRI vendors. An additional introduction was Arterys? regurgitation evaluation software that offers several ways to view regurgitation, which has traditionally been difficult to assess on MRI. One view visualizes blood flow velocities with arrows to show direction of flow and a color code to show the speed of the flow. It presents very similar to cardiac ultrasound color flow Doppler. The software can help identify regurgitation jets, vortices and sheer wall stresses, and offers automated quantification. In cardiovascular research, sheer stress evaluation has become a big area of interest because it is believed these stresses may play a role in the formation of atherosclerosis, the degradation of heart valve function, and possibly play a role in the progression of heart failure. So, Arterys also introduced a research sheer stress analysis software package.

20. National Liquid State Physics Symposium 16 December 2016

20. National Symposium on  Liquid State Physics was held in Piri Reis University.

The symposium was obtaining various studies about liquids as water and climate change, simulating strait systems, oceans, spin glass phases, liquid crystals, serum transferring,  swollen gells, GO composites, metals with  glass-like structure, super hidrophobic polistren and, biofluids {yes, this was mine ;) }.

It was an incontrovertible experience for me that i could meet new studies in the field and spend nameable times with  physics authors.

Many thanks to organizing comitee (especially to Gülşen Evingür) and Sevtap Yıldız Özbek.

‘Go with the flow’ by Victoria Stoll

The British Heart Foundation (BHF) announced the winners of its annual ?Reflections of Research? image competition, reflecting the charity?s research into heart and circulatory disease.
The winning image ? titled ?Go with the flow,? by Victoria Stoll, a BHF-funded researcher at the University of Oxford ? captures the blood flowing within an adult heart frozen in time. Blood flows within the main pumping chambers (ventricles) of the heart and the vessels leaving the heart. The blue flow is blood that lacks oxygen and is travelling to the lungs. The red flow is blood that has been through the lungs and received oxygen and is now ready to be pumped around the body.
Stoll is using this type of imaging, four-dimensional cardiac magnetic resonance imaging (MRI), to look at the blood flow in four dimensions within the hearts of people with heart failure, whose hearts are not pumping effectively. She has already found that in people with severe heart failure the blood flows around the heart in a more disordered and disrupted pattern.

PRINT THYSELF

This sort of procedure is becoming more and more common among doctors and medical researchers. Almost every day, I receive an e-mail from my hospital?s press office describing how yet another colleague is using a 3-D printer to create an intricately realistic surgical model?of a particular patient?s mitral valve, or finger, or optic nerve?to practice on before the actual operation. Surgeons are implanting 3-D-printed stents, prosthetics, and replacement segments of human skull. The exponents of 3-D printing contend that the technology is making manufacturing more democratic; the things we are choosing to print are becoming ever more personal and intimate. This appears to be even more true in medicine: increasingly, what we are printing is ourselves.

Measure Your Blood Flow

The inventors of the new ?epidermal electronic? sensor system say it is ready for use in a clinical setting, specifically for monitoring skin health, for example in patients who have recently had skin grafts. They say down the road it may also be possible to use it inside the body. In a recent demonstration, the researchers showed that the device can record accurate data from human subjects about the flow of blood in larger vessels, specifically veins in the forearm, as well as in the network of tiny vessels near the surface of the skin.

Compared with state-of-the-art methods for noninvasively measuring blood flow, which rely on optical systems or ultrasound technology, the new sensor is much simpler and less expensive, says John Rogers, one of the inventors and a professor of materials science and engineering at the University of Illinois at Urbana-Champaign. More importantly, he says, it is much less sensitive to motion thanks to the way it ?intimately laminates? to the skin.

Characteristics of the blood flow in any given tissue are a good indicator of that tissue?s health. Some conditions, like infection and inflammation, can lead to an increase in local blood flow, whereas others, like atherosclerosis, heart failure, and diabetes, can cause a decrease. If doctors could precisely and even continuously monitor this flow, they could better tailor care to individual patients and conditions.

3D Printing for Pediatric Cardiothoracic Surgeons

Having worked in product development for the past few years, Dr. Enrique Garcia had seen what 3D printers were capable of and began investigating the possibilities for creating models for pediatric cardiologists to use before an operation. She began by asking surgeons from around the country what they thought of the idea. To say that their response was overwhelmingly positive is an understatement. The value of this idea was immediately apparent.

?Pediatric heart surgery is the hardest thing that I can imagine a person doing. A surgeon doesn?t know what he?s going to see until he opens a child?s chest. Every heart is different and every cardiopathy is different,? said Garcia. ?A baby?s heart is the size of a walnut, and surgeons need to go in and move around structures that are as small and thin as a human hair; and they?re doing it with their own two hands. And all of this is occurring against a ticking clock.?

?Having something in your hands, and being able to turn it any way you want, and to be able to cut and open it up and see the inside; and to be able to physically hold it, to feel it, is something that can?t be replicated in a computer.?

cSound

Researchers have created software that can model internal organs in ‘extreme 4D’.
The system, dubbed cSound, is currently being used by cardiologist Bijoy Khandheria, who has been fixing broken hearts for more than three decades.

Dr Khandheria describes the images as ‘exquisite’, and says it’s like opening up someone’s chest and watching their heart beat.’

‘Traditionally, ultrasound has allowed us to see the heart but not in as much detail as we might like,’ he said.
‘We used the signal to image the heart layer by layer, almost like a butcher using a knife, and then mentally splice the layers together to see the whole picture’.
Dr Khandheria and his colleagues at Aurora St Luke’s Medical Center in Milwaukee, have recently started ‘extreme 4D’ software.
The images are so clear that it allows doctors to see how blood swirls around clots in arteries.
This can then be used to measure the severity of blood leakage around the valves and assess the damages.
‘It’s almost as if I took out the valve and started turning it with my hands,’ said Dr Khandheria.
