  • An actuated larynx phantom for pre-clinical evaluation of droplet-based reflex-stimulating laryngoscopes 
    Fast, Jacob Friedemann; He, Jiazhen; Ortmaier, Tobias; Jungheim, Michael; Ptok, Martin; Kahrs, Lüder Alexander (Berlin : De Gruyter, 2019)
    The laryngeal adductor reflex (LAR) is an important protective function of the larynx to prevent aspiration and potentially fatal aspiration pneumonia by rapidly closing the glottis. Recently, a novel method for targeted ...
  • Cochlear shape description and analyzing via medial models 
    Gaa, Johannes; Kahrs, Lüder Alexander; Müller, Samuel; Majdani, Omid; Ortmaier, Tobias (Bellingham, Wash. : SPIE, 2015)
    Planning and analyzing of surgical interventions are often based on computer models derived from computed tomography images of the patient. In the field of cochlear implant insertion the modeling of several structures of ...
  • Comparison of tablet-based strategies for incision planning in laser microsurgery 
    Schoob, Andreas; Lekon, Stefan; Kundrat, Dennis; Kahrs, Lüder Alexander; Mattos, Leonardo S.; Ortmaier, Tobias (Bellingham, Wash. : SPIE, 2015)
    Recent research has revealed that incision planning in laser surgery deploying stylus and tablet outperforms stateof-the-art micro-manipulator-based laser control. Providing more detailed quantitation regarding that approach, ...
  • Endoluminal non-contact soft tissue ablation using fiber-based Er:YAG laser delivery 
    Kundrat, Dennis; Fuchs, Alexander; Schoob, Andreas; Kahrs, Lüder Alexander; Ortmaier, Tobias (Bellingham, Wash. : SPIE, 2016)
    The introduction of Er:YAG lasers for soft and hard tissue ablation has proven promising results over the last decades due to strong absorption at 2.94 μm wavelength by water molecules. An extension to endoluminal applications ...
  • Experimental visualization of labyrinthine structure with optical coherence tomography 
    Mohebbi, Saleh; Mirsalehi, Marjan; Kahrs, Lüder Alexander; Ortmaier, Tobias; Lenarz, Thomas; Majdani, Omid (Mashhad : Mashhad University of Medical Sciences, 2017)
    Introduction: Visualization of inner ear structures is a valuable strategy for researchers and clinicians working on hearing pathologies. Optical coherence tomography (OCT) is a high-resolution imaging technology which may ...
  • Fast and automatic depth control of iterative bone ablation based on optical coherence tomography data 
    Fuchs, Alexander; Pengel, Steffen; Bergmeier, Jan; Kahrs, Lüder Alexander; Ortmaier, Tobias (Bellingham, Wash. : SPIE, 2015)
    Laser surgery is an established clinical procedure in dental applications, soft tissue ablation, and ophthalmology. The presented experimental set-up for closed-loop control of laser bone ablation addresses a feedback ...
  • Feature tracking for automated volume of interest stabilization on 4D-OCT images 
    Laves, Max-Heinrich; Schoob, Andreas; Kahrs, Lüder Alexander; Pfeiffer, Tom; Huber, Robert; Ortmaier, Tobias (Bellingham, Wash. : SPIE, 2017)
    A common representation of volumetric medical image data is the triplanar view (TV), in which the surgeon manually selects slices showing the anatomical structure of interest. In addition to common medical imaging such as ...
  • Forces and trauma associated with minimally invasive image-guided cochlear implantation 
    Rohani, Pooyan; Pile, Jason; Kahrs, Lüder Alexander; Balachandran, Ramya; Blachon, Gregoire S.; Simaan, Nabil; Labadie, Robert F. (London : SAGE Publications Ltd., 2014)
    Objective. Minimally invasive image-guided cochlear implantation (CI) utilizes a patient-customized microstereotactic frame to access the cochlea via a single drill-pass. We investigate the average force and trauma associated ...
  • Methods for a fusion of Optical Coherence Tomography and stereo camera image data 
    Bergmeier, Jan; Kundrat, Dennis; Schoob, Andreas; Kahrs, Lüder Alexander; Ortmaier, Tobias (Bellingham, Wash. : SPIE, 2015)
    This work investigates combination of Optical Coherence Tomography and two cameras, observing a microscopic scene. Stereo vision provides realistic images, but is limited in terms of penetration depth. Optical Coherence ...
  • Methods for intraoperative, sterile pose-setting of patient-specific microstereotactic frames 
    Vollmann, Benjamin; Müller, Samuel; Kundrat, Dennis; Ortmaier, Tobias; Kahrs, Lüder Alexander (Bellingham, Wash. : SPIE, 2015)
    This work proposes new methods for a microstereotactic frame based on bone cement fixation. Microstereotactic frames are under investigation for minimal invasive temporal bone surgery, e.g. cochlear implantation, or for ...
  • Panorama imaging for image-to-physical registration of narrow drill holes inside spongy bones 
    Bergmeier, Jan; Fast, Jacob Friedemann; Ortmaier, Tobias; Kahrs, Lüder Alexander (Bellingham, Wash. : SPIE, 2017)
    Image-to-physical registration based on volumetric data like computed tomography on the one side and intraoperative endoscopic images on the other side is an important method for various surgical applications. In this ...
  • Semantic denoising autoencoders for retinal optical coherence tomography 
    Laves, Max-Heinrich; Ihler, Sontje; Kahrs, Lüder Alexander; Ortmaier, Tobias (Bellingham, Wash. : SPIE, 2019)
    Noise in speckle-prone optical coherence tomography tends to obfuscate important details necessary for medical diagnosis. In this paper, a denoising approach that preserves disease characteristics on retinal optical coherence ...
  • Stereo vision-based tracking of soft tissue motion with application to online ablation control in laser microsurgery 
    Schoob, Andreas; Kundrat, Dennis; Kahrs, Lüder Alexander; Ortmaier, Tobias (Amsterdam : Elsevier BV, 2017)
    Recent research has revealed that image-based methods can enhance accuracy and safety in laser microsurgery. In this study, non-rigid tracking using surgical stereo imaging and its application to laser ablation is discussed. ...
  • User evaluation study on illumination requirements to design an augmented reality projector for open liver surgery 
    Ilango, Shivaraman; Knöchelmann, Marvin; Kahrs, Lüder Alexander; Wolf, Alexander; Ortmaier, Tobias; Lachmayer, Roland (Bellingham, Wash. : SPIE, 2018)
