WebA Digitally Reconstructed Radiograph (DRR) is a simulation of a conventional 2D x-ray image, created from computed tomography (CT) data. A radiograph, or conventional x-ray image, is a single 2D view of total x-ray absorption through the body along a given axis.Two objects (say, bones) in front of one another will overlap in the image. By contrast, a 3D CT … WebCombine SEL-CTs and Summing CTs to build an inexpensive maximum demand ammeter that sums up to five individual CT inputs into a single output. This solution lets you … WebThe sum of the currents can add up to Zero e.g. in case of a differential current measurement. The standard application is the addition of currents of the same phase. With a reverse connection of the main current transformers … greatest team of all time meme
