“…JWAVE simulates the solution of time-harmonic wave propagation problems by solving the heterogeneous Helmholtz equation in the complex domain, using a regular Fourier spectral collocation method and linear iterative solvers such as restarted generalized minimal residual method (GMRES). 49,50 Absorbing boundary conditions are enforced using a PML, 51 while the definition of the sources is done by projecting them on the discrete collocation grid by approximately convolving them with the band limited interpolant. 52 The source field is modeled as a mass source.…”

Computational models of acoustic wave propagation are frequently used in transcranial ultrasound therapy, for example, to calculate the intracranial pressure field or to calculate phase delays to correct for skull distortions. To allow intercomparison between the different modeling tools and techniques used by the community, an international working group was convened to formulate a set of numerical benchmarks. Here, these benchmarks are presented, along with intercomparison results. Nine different benchmarks of increasing geometric complexity are defined. These include a single-layer planar bone immersed in water, a multi-layer bone, and a whole skull. Two transducer configurations are considered (a focused bowl and a plane piston operating at 500 kHz), giving a total of 18 permutations of the benchmarks. Eleven different modeling tools are used to compute the benchmark results. The models span a wide range of numerical techniques, including the finite-difference time-domain method, angular spectrum method, pseudospectral method, boundary-element method, and spectral-element method. Good agreement is found between the models, particularly for the position, size, and magnitude of the acoustic focus within the skull. When comparing results for each model with every other model in a cross-comparison, the median values for each benchmark for the difference in focal pressure and position are less than 10% and 1 mm, respectively. The benchmark definitions, model results, and intercomparison codes are freely available to facilitate further comparisons.

“…Esta herramienta puede ser realmente útil si se pretende evaluar el desempeño de los algoritmos de reconstrucción o de distintas configuraciones de los elementos que conforman al sistema de TCUS de forma anticipada a su armado. En este contexto, se presentó como una opción viable el uso del programa j-Wave [16]. Este novedoso simulador da la posibilidad de realizar simulaciones acústicas rápidas, paralelizables y personalizables sacando provecho de la aceleración por GPU.…”

En este trabajo se aborda el estudio y desarrollo de un sistema que posibilita la obtención de imágenes de ultrasonido bidimensionales. El enfoque principal del desarrollo consistió en conseguir que el sistema sea apto para reutilizarlo en otras aplicaciones de índole semejante. Para este propósito, se empleó un transductor de inmersión comercial, se diseñó e implementó un subsistema para explorar la muestra bajo estudio desde distintos ángulos, y se desarrolló un algoritmo de reconstrucción para generar las imágenes a partir de las mediciones acústicas registradas. Asimismo, se desarrolló un modelo computacional para simular el funcionamiento del tomógrafo en su totalidad. Para evaluar el desempeño del sistema real y el simulado, se utilizaron dos figuras de mérito (correlación de Pearson y relación señal a ruido pico) entre las imágenes de referencia y las reconstrucciones obtenidas.
