CTF determination and correction for low dose tomographic tilt series.
The resolution of cryo-electron tomography can be limited by the first zero of the microscope's contrast transfer function (CTF). To achieve higher resolution, it is critical to determine the CTF andExpand

Physical characterization of a high-resolution CCD detector for mammography.
The physical characteristics of charge-coupled device (CCD) mammography detector with 16-bit dynamic range and 27 microm detector element size were investigated. The detector, with an active area ofExpand
