Phantom device for adjusting prostate magnetic resonance imaging protocol in patients with hip metal structure

摘要

This useful model belongs to the field of medical technology,Image quality control,Magnetic resonance imaging of metal structures in areas of interest. Technically, we know a useful model similar to what we call,This is a phantom for monitoring diffusion weighted image parameters in magnetic resonance imaging (useful model Ru 187202 U1),Disadvantages of prostate imaging in patients with metal structures include the inability to place the implant in the phantom, and the lack of Simulate the geometric characteristics of the prostate. Technical challenges,A useful modelIt provides a possibility to simulate the measured diffusion coefficient and prostate geometric characteristics, and place the implant in the phantom,This will help to adjust the prostate magnetic resonance imaging protocol in patients with hip metal structure. The technical achievement isIn the establishment of a prostate imaging quality evaluation device for magnetic resonance imaging in patients with hip metal structureThat is, the accuracy of measuring the diffusion coefficient,The geometry of the prostate,Including the central and peripheral areas,And tumors,Non uniformity of image brightness,The nonlinearity of the image,Signal to noise ratio
