RATOC Otolith analysis

　This system measures the number and spacing of concentric rings in otoliths, equilibrium stones, fish scales, etc. in the inner ear of fish, and enables statistical processing of the measurement data.


Usage
★☆spanApplication to otolith day ring analysis, scale annual ring analysis, growth curve/survival curve analysis

feature
★Scale patterns can be tracked while adjusting the focus on the live image
  • Ring patterns can be marked on the microscope live image.
  • Focusing and ring pattern marking can be done at the same time.
  • Marking is possible while operating the microscope without the need to freeze the image.
★Automatic measurement of ring pattern interval and graph display of ring pattern interval
  • The intersecting point between the measurement line and the ring pattern can be automatically determined,
    and the ring pattern interval can be measured automatically.
  • Since the ring pattern interval is displayed in a graph in real time, it is possible to check
    for measurement errors on the spot.
★Wide-field otoliths can also be measured
  • If the ring pattern does not fit in one field of view, it can be measured while moving
    the microscope stage and moving the field of view.
  • Interlocking with an XY stage with a digital scale is also possible.
★Correlation between fluorescent label and ring pattern image
  • Fluorescent label image and ring pattern image can be superimposed and displayed.
  • Clicking on the fluorescent label will display the data of the corresponding measurement point.
★Clicking on the fluorescent label will display the data of the corresponding measurement point.
  • A dedicated file conversion tool allows you to integrate large amounts of
    measurement data into Excel format files.
