Automatic Unstained Cell Detection in Bright Field Microscopy Abstract Bright field microscopy is preferred over other microscopic imaging modalities whenever ease of implementation and minimization of expenditure are main concerns. This simplicity in hardware comes at the cost of image quality yielding images of low contrast. While staining can be employed to improve the contrast, […]

Cell Culture Monitoring with Novel Bright Field Miniature Microscopy Prototypes Abstract Cell cultures are monitored to develop new drugs, to find efficient ways to produce vaccines and to perform toxicity tests. The cells are cultivated in an incubator and the monitoring steps such as the acquisition of images and the counting of cells are often […]

Motion-Corrected Reconstruction in Cone-Beam Computed Tomography for Knees under Weight-Bearing Condition Abstract Medical imaging plays an important role in diagnosis and grading of knee conditions such as osteoarthritis. In current clinical practice, 2-D radiography is regularly applied under weight-bearing conditions, which is known to improve diagnostic accuracy. However, 2-D images cannot fully cover the complexity […]Motion-Corrected Reconstruction in Cone-Beam Computed Tomography for Knees under Weight-Bearing Condition Abstract Medical imaging plays an important role in diagnosis and grading of knee conditions such as osteoarthritis.

Evaluation Methods for Stereopsis Performance Abstract Stereopsis is one mechanism of visual depth perception, which gains 3D information from the displaced images of both eyes. Depth is encoded by disparity, the offset between the corresponding projections of one point in both retinas. Players in ball sports, who are adapted to highly competitive environments, can be […]

Hybrid RGB/Time-of-Flight Sensors in Minimally Invasive Surgery Abstract Nowadays, minimally invasive surgery is an essential part of medical interventions. In a typical clinical workflow, procedures are planned preoperatively with 3-dimensional (3-D) computed tomography (CT) data and guided intraoperatively by 2-dimensional (2-D) video data. However, accurate preoperative data acquired for diagnose and operation planning is often […]Hybrid RGB/Time-of-Flight Sensors in Minimally Invasive Surgery Abstract Nowadays, minimally invasive surgery is an essential part of medical interventions.

Region-of-Interest Imaging with C-arm Computed Tomography Abstract C-arm based flat-detector computed tomography (FDCT) is a promising approach for neurovascular diagnosis and intervention since it facilitates proper analysis of surgical implants and intra-procedural guidance. In the majority of endovascular treatments, intra-procedural updates of the imaged object often are restricted to a small diagnostic region of interest […]Region-of-Interest Imaging with C-arm Computed Tomography Abstract C-arm based flat-detector computed tomography (FDCT) is a promising approach for neurovascular diagnosis and intervention since it facilitates proper analysis of surgical implants and intra-procedural guidance.
