Sinopsis: Bioimagiologia is a lecture + practical course where students learn a variety of techniques used to obtain images of cells, tissues, organs, embryos and adult organisms. The techniques addressed include all major light microscopy (wide-field, fluorescence, confocal, multiphoton, super-resolution), macro & mesoscopy (light-sheet and optical tomography), and medical imaging techniques such as ultrasound/MRI/CT imaging, and pre-clinical imaging. We also adress digital image acquisition (including techniques such as temporal compression and high-speed video, time-lapse and 3D/4D images), processing and analysis (densitometry, 3D image reconstructions, cell tracking, etc...) using mainly the open-source imageJ software. During the practicals, students attend demonstrations and use different types of equipment to obtain images to later process and analyse. The course also includes lectures by invited speakers and visits to microscopy labs outside UL. Classes are taught in english or portuguese depending on students choice.
