Barbano R, Kereta Z, Hauptmann A, Arridge S, Jin B
Inverse Probl . 2023 Sep; 38(10):104004. PMID: 37745782
Deep learning-based image reconstruction approaches have demonstrated impressive empirical performance in many imaging modalities. These approaches usually require a large amount of high-quality paired training data, which is often not...

Macdonald C, Arridge S, Munro P
Sci Rep . 2023 Jan; 13(1):1507. PMID: 36707545
We examine the inverse problem of retrieving sample refractive index information in the context of optical coherence tomography. Using two separate approaches, we discuss the limitations of the inverse problem...

Mozumder M, Hauptmann A, Nissila I, Arridge S, Tarvainen T
IEEE Trans Med Imaging . 2021 Dec; 41(5):1289-1299. PMID: 34914584
Diffuse optical tomography (DOT) utilises near-infrared light for imaging spatially distributed optical parameters, typically the absorption and scattering coefficients. The image reconstruction problem of DOT is an ill-posed inverse problem,...

Arridge S, Ehrhardt M, Thielemans K
Philos Trans A Math Phys Eng Sci . 2021 May; 379(2200):20200205. PMID: 33966461
Imaging is omnipresent in modern society with imaging devices based on a zoo of physical principles, probing a specimen across different wavelengths, energies and time. Recent years have seen a...

Papadimitriou K, Vidal Rosas E, Zhang E, Cooper R, Hebden J, Arridge S, et al.
Biomed Opt Express . 2020 Oct; 11(7):3477-3490. PMID: 33014545
Near-infrared spectroscopy has proven to be a valuable method to monitor tissue oxygenation and haemodynamics non-invasively and in real-time. Quantification of such parameters requires measurements of the time-of-flight of light...

Huynh N, Lucka F, Zhang E, Betcke M, Arridge S, Beard P, et al.
J Biomed Opt . 2019 Sep; 24(12):1-6. PMID: 31535537
Since it was first demonstrated more than a decade ago, the single-pixel camera concept has been used in numerous applications in which it is necessary or advantageous to reduce the...

Davis S, Wisniewski L, Kumar S, Correia T, Arridge S, Frankel P, et al.
Opt Lett . 2018 Nov; 43(22):5555-5558. PMID: 30439894
To improve the imaging performance of optical projection tomography (OPT) in live samples, we have explored a parallelized implementation of semi-confocal line illumination and detection to discriminate against scattered photons....

Tick J, Pulkkinen A, Lucka F, Ellwood R, Cox B, Kaipio J, et al.
J Acoust Soc Am . 2018 Nov; 144(4):2061. PMID: 30404490
The image reconstruction problem (or inverse problem) in photoacoustic tomography is to resolve the initial pressure distribution from detected ultrasound waves generated within an object due to an illumination by...

Papadimitriou K, Dempsey L, Hebden J, Arridge S, Powell S
Biomed Opt Express . 2018 Sep; 9(6):2648-2663. PMID: 30258680
We introduce a compact time-domain system for near-infrared spectroscopy using a spread spectrum technique. The proof-of-concept single channel instrument utilises a low-cost commercially available optical transceiver module as a light...

Markiewicz P, Ehrhardt M, Erlandsson K, Noonan P, Barnes A, Schott J, et al.
Neuroinformatics . 2017 Dec; 16(1):95-115. PMID: 29280050
We present a standalone, scalable and high-throughput software platform for PET image reconstruction and analysis. We focus on high fidelity modelling of the acquisition processes to provide high accuracy and...
