Rpm motion phantom
WebMar 1, 2024 · For activating the gating function, the RPM system was used to track the movement of a marker block on a motion phantom that has an elliptical wheel generating a cycle period of 5.2 seconds. A gating window of 40% to 60% phase was preset to trigger the beam on and off during the plan delivery. WebIncluded with the MRI⁴ᴰ phantom is an intuitive programmable respiratory motion QA software. This locally-installed package enables the control of the phantom’s motion, …

WebJun 17, 2024 · Hello there bob37. Thank you for reaching out and for these information you have posted. The DJI Mavic Air 2 has a hovering rotation speed ( average ) : 6000 rpm and a maximum rotation speed ( extreme test ) : 12300 rpm. Thank you. Thanks DJI Stephen, the kv is similar to the old phantom, The calculations are there supporting a four cell pack. Webusing the model 008A. This phantom study allowed them to assess image quality of the 30-mm spherical insert for different motion profiles. In their protocol, an A*cos4(ωt) motion profile was used, where the amplitude of motion A was set to 20 mm and the frequency ω was changed to produce different degrees of motion artifact.
