Adaptive beamforming for photoacoustic imaging [PDF]
Optics Letters, 2008 An adaptive photoacoustic image reconstruction technique that combines coherence factor (CF) weighting and the minimum variance (MV) method is introduced. The backprojection method is widely used to reconstruct photoacoustic tomography images. Owing to the scattering of light, the quality of the photoacoustic imaging can be degraded.

Multi-Rank Adaptive Beamforming
IEEE/SP 13th Workshop on Statistical Signal Processing, 2005, 2005 This paper presents a multi-rank generalization of the Capon beamformer to accommodate model mismatch in situations where the unknown signal of interest lies in a multidimensional subspace. By expanding the beamforming subspace robustness (or diversity) is achieved at the expense of resolution.

Genetic algorithm assisted adaptive beamforming [PDF]
Proceedings IEEE 56th Vehicular Technology Conference, 2003 Genetic algorithm (GA) assisted beamforming techniques are proposed as an alternative to conventional beamforming algorithms. The design of the corresponding GAs is highlighted and the achievable performance is characterised in terms of the signal-to-interference ratio (SIR) and the signal-to-interference-plus-noise ratio (SINR).
