WebAnswer (1 of 4): They are all subdivisions of the category of deviated drilling. Any intentionally deviated well is by nature directional no matter the angle from 1 degree to 90 from vertical. Slant is different from horizontal by the matter of the angle from vertical. Slant hole can be any angle... WebWe previously developed an OS-EM reconstruction method for rotating multi-segment slant-hole SPECT with compensation for non-uniform attenuation and collimator-detector response. In this study we performed simulations to Investigate the imaging characteristics of RMSSH SPECT mammography using signal-to-noise ratio as a criterion. jean\\u0027s 3z
