positions: (i) the center of the axial FOV and (ii) one-fourth of the axial FOV
(31.75 mm away from the center along axial direction). For each of the two
axial positions, the source was stepped towards the edge of the transverse FOV.
For the central 5 mm of the transverse FOV, the source was stepped at 1 mm
increments and then at 5 mm steps up to the edge of the FOV. </span></p><p style="margin: 0px 0px 0.26px -0.53px;"><span lang="EN-US" style="margin: 0px; color: black; line-height: 116%; font-family: Times New Roman,serif; font-size: 10pt;"> </span></p><p style="margin: 0px 0px 0.26px -0.53px;"><span lang="EN-US" style="margin: 0px; color: black; line-height: 116%; font-family: Times New Roman,serif; font-size: 10pt;"><span style="display: inline !important; float: none; background-color: transparent; color: rgb(0, 0, 0); font-family: gulim,sans-serif; font-size: 13.33px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;">I tried setting up by looking at the following</span></span></p><p style="margin: 0px 0px 0.26px -0.53px;"><span lang="EN-US" style="margin: 0px; color: black; line-height: 116%; font-family: Times New Roman,serif; font-size: 10pt;"><span style="display: inline !important; float: none; background-color: transparent; color: rgb(0, 0, 0); font-family: gulim,sans-serif; font-size: 13.33px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;">this is not yet complete code</span></span></p><p style="margin: 0px 0px 0.26px -0.53px;"><span lang="EN-US" style="margin: 0px; color: black; line-height: 116%; font-family: Times New Roman,serif; font-size: 10pt;"><span style="display: inline !important; float: none; background-color: transparent; color: rgb(0, 0, 0); font-family: gulim,sans-serif; font-size: 13.33px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;"><br></span></span></p><span lang="EN-US" style="margin: 0px; color: black; line-height: 116%; font-family: Times New Roman,serif; font-size: 10pt;"><span style="text-align: left; color: rgb(0, 0, 0); text-transform: none; text-indent: 0px; letter-spacing: normal; font-family: gulim,sans-serif; font-size: 13.33px; font-variant: normal; word-spacing: 0px; display: inline !important; white-space: normal; orphans: 2; float: none; -webkit-text-stroke-width: 0px; background-color: transparent;"><p style="margin: 0px;"><span lang="EN-US" style="margin: 0px;">/gate/source/18CylinderSource_1/attachTo mouse</span></p><p style="margin: 0px;"><span lang="EN-US" style="margin: 0px;">/gate/source/18CylinderSource_1/gps/confine
