Image reconstruction with a circular tranducer array

[carmsignes]

Hello!

I am trying to use kspaceFirstOrder2D to detect and map temperature changes in water, particularly hot and cold regions within a 2D media. For this, I am simulating a circular array, building up from the Array as Sensor example. At the moment, I managed to manually create a for loop to cycle between all the elements of the array, such as that every time one element is emitting and the rest are receiving (therefore, doing N_elements simulations, and saving combined_sensor_data for each of them).

I have access to the traces of the sensor data, but I am trying to use this information to reconstruct the initial density/sound speed maps. However, I cannot find a way to do this. I tried building up on the B-mode linear transducer example, but I do not know how to (or if it is possible) to adapt it to a circular array, as it relies on scan lines.

In short, my questions are:

1. How to do a reconstruction of a 2D density/sound speed field using a circular array?
2. Is there a more elegant way to use the circular array for this purpose, instead of using a loop to perform N_elements simulations and store all the independent data?

Thank you kindly for your help @waltsims ! I can provide with snippets of my code so far or answer any questions!
