headline-marker Karl-Heinz-Höhne-Preis und Dissertation – Frank Heckel gleich zweimal erfolgreich

09 September 2014

As in 2012, a researcher of the ICCAS could receive the award for the 2nd place of the Karl-Heinz-Höhne-Preis (MedVis-Award). Frank Heckel got the honor, which is awarded every two years from the Visual Computing for Biology and Medicine (VCBM) Group, for his scientific work on interactive post-correction of automatically generated segmentation results in oncology. The computer scientist from the Fraunhofer-Institut für Bildgestützte Medizin (MEVIS) has been working as guest researcher at the ICCAS for over one year. Here, he analyzes image qualities for the collaborative project OR.NET and supports the cooperation between the ICCAS and the Fraunhofer MEVIS within the scope of the OR.NET-initiatives.

Four days after the award ceremony, Frank Heckel could celebrate another professional success. He defended his doctoral thesis entitled “Sketch-Based Interactive Segmentation and Segmentation Editing for Oncological Therapy Monitoring“ at the Jacobs University Bremen. In this work, he dealt with methods for more accurate and reproducible volumetric measurements of tumors in computer tomography data. The procedures were developed to support radiologists evaluating the effective of chemotherapy. Heckel’s success at the MedVis-Award is based on findings of the dissertation.

The ICCAS congratulates to the outstanding achievements and looks forward to another year, from now on with Dr. Frank Heckel in the research team.

headline-marker Sandra von Sachsen mit Vortrag auf ICBES in Prag

01 September 2014

Sandra von Sachsen was speaker at the International Conference on Biomedical Engineering and Systems (ICBES) in Prague. At the specialist conference, researchers met who deal with theories and applications of biomedical sciences and biomedical engineering.

Von Sachsen’s lecture on computer-assisted defect classification for the treatment of cervical spinal stenosis presented important research results of the HWS-group – a coding scheme for the description of identified defect characteristics of degenerative modified cervical spinal stenosis and a method for the fully automated detection of stenosis of the spinal canal in the MRT image. The audience asked questions concerning the applicability of the method in the diagnosis of vertebral body fractures. According to Sandra von Sachsen, this is quite possible. A crucial prerequisite is the providing of a greater amount of image data for the image-based classification of the relevant vertebral fractures.

headline-marker ICCAS-Workshop zum Teilprojekt 6 – Demonstratoren im OR.NET

09 August 2014

OR.NET is a collaborative project funded by the Federal Ministry of Education and Research and stands for “Secure and dynamic networking in the operation room”. From the very start, the ICCAS has been partner in nearly all sub-projects of this lighthouse project. Since the beginning of this year, the ICCAS has been working on the coordination of the construction of all demonstrators and on the establishment of the integration demonstrator at the Leipzig location.

About 20 partners including representatives of renowned medical technology companies, manufacturers of clinical information technology, provider of integrated operating rooms as well as scientists from research institutes are involved in the sub-project 6. The synchronization of the partners takes regularly place in workshops. At the end of July, such a workshop was organized by the subproject leaders Max Rockstroh (ICCAS) and Markus Birkle (UKL Heidelberg) at the ICCAS. The workshop included in-house presentations on workflow management and guest lectures about the current work on the central components of the Open Surgical Communication Platform (OSCP). Furthermore, updated versions of the storyboards for the demonstrators were presented. The demonstrators will be used to apply the overall project concepts and systems in a realistic environment.
The workshop on sub-project 6 left enough room for proposed solutions. Besides, participants took the opportunity to inspect the current demonstrator–OR.

headline-marker Dr. Kerstin Denecke bringt Leipzig – Auckland – Forschungsvorhaben ins Rollen

08 August 2014

Last year in autumn, employee of New Zealand’s National Institute for Health Innovation (NIHI) visited the ICCAS to explore common research interests. They already showed interest in working together with the ICCAS at that time. Now the return visit followed by Dr. Kerstin Denecke, who traveled to Auckland with plenty information material about the ICCAS and the work of the research group Digital Patient- and Process Modell. Her points of reference were the NIHI – where studies for information technologies in the healthcare sector are conducted – and the Department of Computer Science at the University of Auckland. Furthermore, an initial meeting with the Bioengineering Institute took place which also deals with patient modelling.

The conversations at the NIHI were successful. Both sides see benefits in a closer cooperation. While the Leipzig scientists are leading in methodical development, the Auckland researchers have much to offer in the field of patient studies. The reason for that is a good availability of patient data gathered over decades. Just as the ICCAS, the National Institute endeavors developments of standardized applications which use openEHR – a good reason to remain in contact.
Further research periods are planned. The Leipzig – Auckland – Research is taking shape.

headline-marker Dabeisein während der Digital Operating Room Summerschool (DORS) des ICCAS

DORS 2014 When the ICCAS – Summerschool will open its doors for one week on 22nd September 2014, participants can expect a richly filled program which has the developments and challenges in the field of information technology for the digital operating room as subject matter.

In the premises of the new Augusteum and the Bibliotheca Albertina, experienced scientists from medicine, engineering and computer science will share their experiences in the fields of medical image processing, computer vision and IT-technologies. They will also provide advisory support to the participants. Furthermore, hospital operators speak about the possibilities of implementing new IT-infrastructures in their institutions. During a practical session participants will be introduced into the human physiology and anatomy. An operating room visit will show the current state of the art OR-technologies and workflows in practice. Latest developments can finally be tested on prototypes and simulators in the ICCAS Concept-OR.

Especially young researchers and Ph.D. students should feel concerned who want to face the new requirements on personalized medicine and who want to receive firsthand knowledge from experts. But all other interested persons who are looking for a direct exchange within the scientific community of computer-assisted surgery are very welcome.

The number of participants is limited. Registrations can be submitted until 31st August 2014.
The ICCAS is looking forward to informative days in Leipzig where also the mutual acquaintance should not be neglected.

headline-marker DPM-Beitrag auf 37. ACM SIGIR Konferenz in Australien

23 July 2014

Information processing and knowledge management are important workspaces of the DPM research area. Sentiment Analysis of clinical texts is one part of it and the specialty of Yihan Deng. The computer scientist reported about the current research results of this rather unusual method of information retrieval in the medical field at this year’s International ACM SIGIR Conference in Gold Coast (Australia). Among the participants was also DPM junior research group leader Dr. Kerstin Denecke, who is involved in the investigations just like the physician Matthäus Stöhr. The scientists prove that medical records are far away from being objective data sets. They rather include important observations and assessments of the clinical staff about the current health situation of the patients. This allows deducing indications for further therapeutic measures. The sentiment analysis can thus provide important information for the digital patient model which otherwise would remain hidden in the patient records.

The conference – organized by the Association for Computing Machinery (ACM) and the Special Interest Group on Information Retrieval (SIGIR) – is one of the most important events on the topic of “Information Retrieval”. Here, scientists come together who are concerned with the recognition, organization, storage, retrieval and distribution of information in public and private sectors.

headline-marker Neun Jahre Forschung am ICCAS – Dr. Stefan Bohn sagt Adieu

Dr.-Ing. Stefan Bohn17 July 2014

If anyone knows how the research at the ICCAS got rolling, then Dr. Stefan Bohn. The likeable scientist was one of the first employees in the founding year of the Innovation Center. Now, after nearly nine years of work he leaves his employment in the Semmelweisstraße to start a new career. It is with deep regret that the ICCAS lets him go, because with Stefan Bohn it loses a reliable, dedicated and very creative colleague.

Already in 2005, Bohn brought with his Master of Biomedical Engineering important knowledge about the development of medical technology systems into the ICCAS. From the beginning, he worked on the conception and implementation of a system architecture for the vendor-independent integration of medical devices, clinical IT systems and surgical assistant systems. These activities also included the doctoral thesis which he successfully defended at the Leipzig University in 2013. Health professionals and patients at the Leipzig University Hospital already benefit from the suitable overall system. Solution strategies of the engineer can also be found in the BMBF-funded joint project OR.NET. In addition, Dr. Bohn was involved in the conception and construction of the ICCAS demonstrator OR which is used today for the preclinical testing of new technologies. Most recently, he worked on the completion of the clinical information system oncoflow which received an innovation award this year. Besides the leading of scientific and clinical projects, Stefan Bohn was also active in teaching and got involved with the ICCAS at many internal and external events.

Nine years of excellent collaboration, dynamic commitment and outstanding scientific achievements will be hard to substitute. The team of the ICCAS thanks the long-time colleague a lot for his great efforts for the benefit of the institute and its employees. It wishes him all the very best for the future and furthermore a good nose for medical technology innovations, because Dr. Stefan Bohn will stay within the medical technology sector at his new place of activity.

headline-marker ICCAS empfängt russische Delegation

10 July 2014

A delegation of academics, physicians and students from the Faculty of Fundamental Medicine of the Buryat State University in Ulan-Ude visited the ICCAS on 9th July 2014.
After Professor Thomas Neumuth had warmly welcomed the guests from the capital of the Russian Republic of Buryatia, Mario Cypko and Stefan Franke gave insights into current research work at the ICCAS. Mario Cypko presented previous results and further projects relating to the digital patient model. He initiated the guests into the development and use of Multi-Entity Bayesian Networks for improving the therapeutic decision making. Following, interesting questions about actuality and scope of the applicability and about privacy had to be answered.
During the live demonstration in the ICCAS concept-OR Stefan Franke was closely surrounded by the participants. Whether surgical milling tool, ultrasound with navigating puncture needle or navigation system for ENT surgery – the modern devices were carefully examined. Unfortunately, the guests had very little time in their bags, because the ICCAS was only one of many program points of the Leipzig stay.

The Buryat State University is one of the oldest universities in Siberia and an important establishment for modern science and higher education in the Russian Republic. Professors and students of the Faculty of Medicine regularly organize fact-finding trips to technologically advanced institutions in Germany and other European countries to promote the concept of Integrative Medicine using traditional and modern methods of treatment and innovative technologies and to forge collaborations.

headline-marker Erfolgreiche Präsentation auf dem International Congress of Computer Assisted Radiology and Surgery

03 July 2014

With visionary thoughts in mind the ICCAS participants of the 28th CARS-Congress returned to their research places.
Both the own technical contributions and the visits of other sessions and presentations strongly boosted the dialogue with international medical experts and clinical informatics. After his lecture on system development for the modeling of medical treatment decisions Mario Cypko received a cooperation request from an institute in Moscow. Furthermore, he could take new approaches and solutions to ethical questions for his project, concerning computer-assisted therapeutic decisions.
Matthäus Stöhr’s tumor board – analysis from a researching clinician’s point of view also met with great response. An US American company sees great potential in the information models and is striving for cooperation with the ICCAS.
Also Philipp Liebmann found suggestions for the further research work of the Standard-group. In his lecture on the status of DICOM and IHE in surgery, he presented existing solutions as well as data objects and IHE-profiles currently under development. During the DICOM WG 24 Meeting further development approaches were discussed.
