Convert 3d image into 2d matlab8/23/2023 This step is performed using scanConversion % set the desired size of the image This means the scan lines must be converted from polar coordinates to Cartesian coordinates. However, in this example, the scan lines are taken at different steering angles. Scan_lines(angle_index, :) = transducer.scan_line(sensor_data) Īfter simulation, the scan lines are processed before display following the steps described in Simulating B-mode Ultrasound Images. % extract the scan line from the sensor data Sensor_data = kspaceFirstOrder3D(kgrid, medium, transducer, transducer, input_args) Transducer.steering_angle = steering_angles(angle_index) % loop through the range of angles to test The scan lines are then simulated sequentially, with the value for transducer.steering_angle modified for each scan line. This is used to replace both the source and sensor inputs. In this example, a 64 element sector transducer is defined with all the elements active. The simulation is run in a similar same way to Simulating B-mode Ultrasound Images.
