Good-day.
I am designing ultrasonic transducer array. The scheme what I am trying to make is axially symmetric circular design, so called annular array.
What I want to simulate is ultrasonic radiation pattern of the annular array.
The problem what I faced is "how to define geometries of transducer array"
I think K-WAVE dosen't support the annular array scheme.
However, is there any way to simulate the annular array scheme using K-WAVE toolbox?
Thank you in advance.
Hi Joontaek Jung,
There is no in-built way to specify an annular array. However, you could create an annular array by defining source.p_mask in the shape of the array (e.g., a disk in a plane), and then assign the source values to source.p in ring shaped blocks, being careful to order the source points following MATLAB's column-wise linear matrix indexing. For example, if the source is centred on the grid, you could order the points based on radius and angle, similar to reorderSensorData.
Hope that helps,
Brad.
