Alternatively, you can use the <code>position</code> property, along with <code>element_width</code>, <code>element_length</code>, and <code>element_spacing</code> 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 <code>kgrid.x_vec</code> etc).</p> <p>Brad </p> http://www.k-wave.org/forum/topic/accurate-transducer-array-position#post-7989 Tue, 22 Dec 2020 12:19:08 +0000 aelbekkali 7989@http://www.k-wave.org/forum/ <p>Hi all<br /> can you chekc my request?<br /> thanks </p> http://www.k-wave.org/forum/topic/accurate-transducer-array-position#post-7986 Wed, 16 Dec 2020 23:10:15 +0000 aelbekkali 7986@http://www.k-wave.org/forum/ <p>Hi All<br /> I am actually working on this example<br /> <a href="http://www.k-wave.org/documentation/example_us_bmode_linear_transducer.php" rel="nofollow">http://www.k-wave.org/documentation/example_us_bmode_linear_transducer.php</a><br /> I need to know the acurate the accurate position of each transducer array element (cartesian coordinate)<br /> there is a command called :<br /> transducer.active_elements_mask<br /> but it returns a 3d matrix filled with zeros and ones. ones for the voxels occupied by the transducer.</p> <p>how can i get the cartesian position of the center of each transducer element.</p> <p>Best regards </p>
