Methods, apparatuses and computer program products for generating regions of interest using gestures via a user interface
View Patent ↗An apparatus is provided for generating a region(s) of interest for a medical image(s). The apparatus includes at least one memory and at least one processor configured to receive an indication of one or more touches at corresponding locations on a touch enabled display. The respective touches define a touch point at the corresponding location. The processor is further configured to generate one or more regions of interest associated with areas of a medical image(s) responsive to receipt of the indications. A location of respective regions of interest corresponds to locations of touch points. The processor is further configured to define a diameter of regions of interest based on a width/pressure of the touch points and define the regions of interest to include a disc including a contour(s). The regions of interest correspond to an area for annotating the medical image(s). Corresponding computer program products and methods are also provided.
