Kilovoltage cone-beam computerized tomography (kV-CBCT) systems integrated into the gantry of linear accelerators can be used to acquire high-resolution volumetric images of the patient in the treatment position. Using on-line software and hardware, patient position can be determined accurately with a high degree of precision and, subsequently, set-up parameters can be adjusted to deliver the i...

Generative Adversarial Networks (GANs) have been widely used and it is expected to use for the clinical examination image. The objective of current study was synthesize material decomposition images bone-water (bone(water)) fat-water (fat(water)) reconstructed from dual-energy computed tomography (DECT) using an equivalent kilovoltage-CT (kV-CT) image a deep conditional GAN. effective atomic nu...
