Deep Resolve Sharp is a Close deep learning algorithm and increases the perceived sharpness. Please note: In this Job Aid, the focus will be on some application strategies of Deep Resolve. These strategies depend on the body region examined, the coil, and the contrast medium. The strategies can also be combined with each other. 3 Effective Date: 03 Feb 2021 | HOOD05162003156399 Unrestricted © Siemens Healthineers, 2021 Deep Resolve – SIEMENS Healthineers Deep Resolve Protocol Overview HR 1 SR_I-spine_12_tse_sag AR 2020 08 07-09:39:29-00021 MAGNETOM Sola #171/1900 F. 120Y MR XA30 CURRENT HE'S +LPH Depending on the SNR level of the original protocol or the image quality that you want to achieve, you can select between the following combinations of Deep Resolve (DR): TP F397 SP.R128 FoV 260-250 1 Deep Resolve Gain: suppression of locally 307 384. 1.
