The stereomicroscope is a light microscope that works with separate beam inputs and in this way creates a spatial impression in the sense of three-dimensionality. Stereomicroscopes correspond to either the Greenough or the Abbe type, with some additional special forms existing. In applied medicine, the devices are used in variations as slit lamps and colposcopes. … Stereomicroscope: Applications & Health Benefits
As early as the mid-17th century, the microscope, invented fifty years earlier, enabled natural scientists to conduct new research. Blood cells, sperm, and anatomical structures were discovered, and it began to be used to search for causes of disease. Many findings would be unthinkable even today without this tool. Cells and tissues – basic substance … Smears and Biopsies
The term scanning probe microscope covers a range of microscopes and associated measurement techniques that are used to analyze surfaces. As such, these techniques fall under surface and interfacial physics. Scanning probe microscopes are characterized by passing a measuring probe over a surface at a small distance.

What is a brain biopsy? A biopsy is a tissue sample taken from a specific area of the body. Consequently, one speaks of a brain biopsy when sample material is taken from the brain. One has to decide between the different sections of the brain. Samples can be taken particularly well from the superficial areas … Brain biopsy
Preparation In the preparation for a brain biopsy, the indication initially plays an important role. Due to some severe complications, the benefits of the biopsy should be carefully weighed. If, however, preliminary examinations reveal the suspicion of a malignant disease, the biopsy must be performed for meaningful therapy planning. Before the biopsy is performed, precise … Preparation | Brain biopsy
Results The results of brain biopsy vary considerably depending on the underlying disease. For example, in the case of spatial demands, a distinction should first be made between benign and malignant processes. Then it must be determined more precisely from which brain tissue the lesion originates. In this way, in addition to the individual large … Results | Brain biopsy
Duration The duration of a brain biopsy is usually determined by how many biopsies have to be taken and how easily the affected areas can be reached. If the biopsy is performed under general anesthesia, the duration of the anesthesia induction and ejection must also be added. Due to the good technical preparation using computer … Duration | Brain biopsy
