   Hi All
   I am actually working on this example
   http://www.k-wave.org/documentation/example_us_bmode_linear_transducer.php
   I need to know the acurate the accurate position of each transducer array element (cartesian coordinate)
   there is a command called :
   transducer.active_elements_mask
   but it returns a 3d matrix filled with zeros and ones. ones for the voxels occupied by the transducer.

   how can i get the cartesian position of the center of each transducer element.

   Best regards

   Hi aelbekkali,

   If you just want to convert you binary matrix to Cartesian positions you can use grid2cart. Alternatively, you can use the position property, along with element_width, element_length, and element_spacing to work out where the element centres are in grid space. The you can then convert this to a Cartesian position using the known grid spacing (or using kgrid.x_vec etc).
