Objective: Dedicated measuring instruments for health-related quality of life (HrQoL) gain importance in doctor-patient communication and multiprofessional care teams. However, HrQoL in diagnosis and treatment of brain tumor patients is still routinely screened by clinical scores such as Karnofsky Performance Index (KPI) and clinical neurological s...

Image-guided surgery near anatomical or functional risk structures poses a challenging task for surgeons. To this end, surgical navigation systems that visualize the spatial relation between patient anatomy (represented by 3D images) and surgical instruments have been described. The provided 3D visualizations of these navigation systems are often c...

The follow-up event to the international workshop imagINe surgery: Collaborative Surgical Tool Development in 2017 will focus on the multi-faceted impact of high-tech equipment in operating rooms and perioperative care on surgical education and training. As part of the outcomes of the first imagINe surgery workshop, the organizers have identified t...

Historically, the role of visual media in diagnostic narratives seems clear and unambiguous. In the age of image-guided therapy, visual control over the human body has attained a completely new level, significantly shaping scientific and public debates on illness, imaging, and medical procedures. Practical functions of medical imaging continue to e...

Augmented reality (AR) visualization of surgically relevant information provides a virtual manifestation of the surgeon's mental projections applied to the surgical area. Thereby, the technology can reduce intraoperative cognitive load and make visual representations more precise and explicit for the surgical team. While several types of AR technol...

Neurosurgical working environments started to change significantly due to the amount of implemented technological support. Computer-assisted surgery (CAS) and image-guided therapy (IGT) enable neurosurgeons to perform complex interventions more safely, faster, with better control and updated intraoperative information. New devices also introduce di...

Objective: Augmented reality (AR) visualization is a promising tool to increase imaging data use efficacy during surgical procedures.

Objective: Image-guided technology supporting brain tumor interventions has become standard in most neurosurgical centers in Europe and the US. Yet there has been no structured qualitative assessment of the practical, context-sensitive demand in neurosurgical visualization so far. In order to improve not only the intraoperative setup and technical...

In surgical practice, skin equals an ever-present reference plain: a physical barrier to the body's inside, a topographical planning surface, a tension-carrying material and a visible screen for all lasting traces of previous interventions, it still steps in for other media such as analogue sketches or digital planning software, further diagnostic...

The evaluation of current practices in neurosurgery reveals a broad range of computer-assisted tools, to some extent well established in clinical routines. Especially in the field of presurgical mapping/planning and intraoperative application of navigation and (near) real-time imaging, several technical solutions are available and installed in many...

Bilder zeigen nicht nur, sondern fordern zu Handlungen auf und bedingen diese. Die zunehmende Verschaltung von Technologien, Körpern und Objekten durch visuelle Schnittstellen wie Graphical User Interfaces, Touchscreens oder Augmented-Reality-Anwendungen macht Betrachtende zuallererst zu Benutzerinnen und Benutzern. Derartige Verknüpfungen von Bild...

Nietzsches thematische wie methodische Auseinandersetzung mit der Medizin seiner Zeit durchzieht vor allem seine mittlere Schaffensperiode wie ein Wasserzeichen, das seine Kerndefinitionen von Wissenschaft über Kultur bis Gesellschaft merklich prägt und sich doch dem systematischen Zugriff der Philosophie bis heute immer wieder entzieht. Von der Wi...

In kaum einem anderen klinischen Fach sind Bild und Handlungsspielraum so sensibel miteinander verschaltet wie in der vergleichsweise jungen Fachdisziplin der Neurochirurgie: Mit Hilfe von Bildern werden in den Neurowissenschaften und in der Klinik komplexe Hirnfunktionen wie zum Beispiel Sprache kartographiert, Bilder schaffen Voraussetzungen für...

Background: Awake surgeries in eloquent gliomas yet have to prove their unique relevance for both the improved functional outcome of the patients in relation to the extent of resection (EOR) and the contested validity of preoperative and intraoperative speech mapping results. Due to variable mapping techniques, performance standards and evaluation...

Wolfgang Herrndorf hat sein Weblog »Arbeit und Struktur« über drei Jahre lang während seiner Hirntumorerkrankung bis zu seinem Suizid geführt und selbst zur späteren Veröffentlichung in Buchform bestimmt. Gattungstheoretisch bedient sich der Text der Form des »Illness diary« bzw. des »Cancer blog«, doch sticht er zugleich aus dieser Gattung durch s...

Bilder, die in der gegenwärtigen neurochirurgischen Praxis die Durchführung von operativen Eingriffen vorbereiten und begleiten, erweisen sich bei näherer Betrachtung als hochgradig konstruiert. Ausgehend von konventionellen 2D-MRT-Schnittbildsequenzen, die die strukturellen Verhältnisse des Gehirns sowie die Lage und Ausdehnung von Tumoren dokumen...

Die Projektvorstellung konzentriert sich auf das medizinische Kernnarrativ der »Diagnose« am Beispiel von Hirntumorerkrankungen. Die Diagnose steht nicht nur am Übergang von Untersuchung und Behandlung, sondern auch an der Schnittstelle disziplinärer und interdisziplinärer Verhandlungen guter medizinischer Praxis und nicht zuletzt zwischen Arzt und...

Rooted in visual cultures of anatomy and pathology, the epistemic complexity and capacity of medical images in clinical practice nowadays postulate a profound understanding of the multidimensionality to which medical visualizations implicitly – and often invisibly – refer. Having been significantly expanded during the past 100 years’ evolution in m...

Im Rahmen bildgeführter Interventionsszenarien in der Medizin kommen gegenwärtig Visualisierungstechniken zum Einsatz, die morphologische und funktionelle Daten multimodal kombinieren und auf diese Weise neue bzw. erweiterte Bildtypen hervorbringen, die den therapeutischen Prozess entweder – präoperativ – maßgeblich bestimmen oder sogar intraoperat...
