Radiation Therapist ☢️🥼 on Instagram: "# What is 4DCT..? 4-Dimensional Computed Tomography. 4DCT is an extension of traditional 3DCT imaging, which captures the tumor’s movement over time. The “4th dimension” refers to the addition of time to the traditional 3D spatial coordinates (x, y, z). # How Does 4DCT Work? Respiratory Gating: The patient’s respiratory cycle is monitored using a respiratory gating system. CT Scans: Multiple CT scans are acquired at different phases of the respiratory cycl
