Background: Heart transplantation is an uncommon treatment for unresectable and non-metastatic primary cardiac sarcomas, and the role of it is unclear. This study aims to offer a survival analysis of it.

We propose and demonstrate a computational imaging technique that uses structured illumination based on a twodimensional discrete cosine transform to perform imaging with a single-pixel detector. A scene is illuminated by a projector with two sets of orthogonal patterns, then by applying an inverse cosine transform to the spectra obtained from the singlepixel detector a full-color image is retrieved. This technique can retrieve an image from sub-Nyquist measurements, and the background noise is easily canceled to give excellent image quality. Moreover, the experimental setup is very simple.
