Abstract
Some embodiments are directed to planning treatment of an area of interest on a tissue section with a motorized treatment tip. The planning may include computing for each pixel in the area of interest a distance to the nearest pixel in the tissue section outside the area of interest or in the background, and selecting a position for a treatment area from the result of the distance transform.
Claims16
A method (700) for planning treatment of an area of interest on a tissue section with a motorized treatment tip, the motorized treatment tip being arranged for treating multiple treatment areas having a geometric shape, the method comprising
- obtaining (710) one or more images representing a tissue section, an area of interest which is part of the tissue section, and background,
- iteratively (720) perform
- computing (721) for each pixel in the area of interest a distance to the nearest pixel in the tissue section outside the area of interest or in the background,
- applying (722) a distance transform to the distance, the distance transform having a preferred value for a radius of the geometric shape and having less preferred values for values higher and/or lower than the radius,
- selecting (723) a position for a treatment area from the result of the distance transform,
- recording (724) the selected position for a treatment area, and removing from the area of interest a geometric shape corresponding to a treatment area at the selected position.
A system for planning treatment of an area of interest on a tissue section with a motorized treatment tip, the motorized treatment tip being arranged for treating multiple treatment areas having a geometric shape, the system comprising:
- one or more processors;
- and one or more storage devices storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations for
- obtaining one or more images representing a tissue section, an area of interest which is part of the tissue section, and background,
- iteratively perform
- computing for each pixel in the area of interest a distance to the nearest pixel in the tissue section outside the area of interest or in the background,
- apply a distance transform to the distance, the distance transform having a preferred value for a radius of the geometric shape and having less preferred values for values higher and/or lower than the radius,
- select a position for a treatment area from the result of the distance transform,
- recording the selected position for a treatment area, and removing from the area of interest a geometric shape corresponding to a treatment area at the selected position.
