Module contents

Time reversal reconstruction module for k-Wave.

This module provides functionality for time reversal reconstruction in photoacoustic imaging. The main class is TimeReversal which handles the reconstruction process using time reversal of the acoustic wave equation.

class TimeReversal

Bases: object

Time reversal reconstruction for photoacoustic imaging.

This class handles time reversal reconstruction of initial pressure distribution from sensor data. It supports both 2D and 3D simulations and automatically applies compensation for half-plane recording.

Parameters:

• kgrid – Computational grid for the simulation

• medium – Medium properties for wave propagation

• sensor – Sensor object containing the sensor mask

• compensation_factor – Factor to compensate for half-plane recording (default: 2.0)

Raises:

ValueError – If inputs are invalid for time reversal

Note

Future versions may support: - GPU acceleration via use_gpu parameter - Differentiable operations via differentiable parameter - Custom boundary conditions via boundary_condition parameter - Elastic wave propagation via elastic parameter

__init__(kgrid, medium, sensor, compensation_factor=2.0)

Initialize time reversal reconstruction.

Parameters:

• kgrid (kWaveGrid) – Computational grid for the simulation

• medium (kWaveMedium) – Medium properties for wave propagation

• sensor (kSensor) – Sensor object containing the sensor mask

• compensation_factor (float) – Factor to compensate for half-plane recording (default: 2.0)

Raises:

ValueError – If inputs are invalid for time reversal

Return type:

None
