“…Then the model (2) can be efficiently solved by using some optimization algorithms, such as FPCA [26], APGL [37], LMaFit [40], 16 and the alternating direction method (ADM) [30,43]. 17 For tensor completion, the low-rank based methods have also been widely studied [9,24,25,42,44].…”

“…41 It is also expected that working Compton cameras based on silicon microstrips and segmented germanium detectors will be demonstrated in the near future. 39,42 In parallel, appropriate analytic 43,44 and iterative 45 image reconstruction algorithms were developed specifically for single-photon images acquired with electronic collimation. Significant development still is required before this technology can be considered to be practical and cost-effective in a clinical arena owing to the complexity of the detector technologies, data acquisition system, and image reconstruction techniques needed for Compton imaging.…”

“…Algunas de las propuestas que se han presentado, consisten en el empleo de píxeles creados a partir de una familia de funciones de enventanado KaiserBessel [68], que son conocidos como blobs, el uso de píxeles naturales en el que la discretización se hace a partir de las formas que surgen de la intersección entre los rayos en el FOV [40] y el empleo de píxeles polares [38,42]. También se ha abordado este problema desde otra perspectiva complementaria al uso de un píxel no cuadrado que consiste en variar la colocación de los píxeles en el FOV siguiendo un esquema que permita reducir el número de píxeles.…”

“…Los píxeles polares se han empleado en cámara Comptom [42], Positron Emission Tomography (PET) [43], Single Photon Emission Computed Tomography (SPECT) [38,44,45] y TAC industriales [46] y han demostrado su capacidad para adaptarse a las simetrías presentes en un escáner TAC. El empleo de estas simetrías hace posible la utilización de una parte de la matriz del sistema y la obtención de la matriz restante mediante el uso de la relación de simetría.…”
