  We study the potential of the MCP-PMT read-out to detect single
photo-electron using transmission lines. Such a solution limits the number of
read-out channels, has a uniform time resolution across the PMT surface and
provides quasi-continuous measurement of the spatial coordinates. The proposed
solution is designed to be used in the BOLD-PET project aiming to develop an
innovative detection module for the positron emission tomography using the
liquid detection media, the tri-methyl bismuth. In this study we use the
commercial MCP-PMT Planacon from Photonis, with 32x32 anode structure. The PCB
gathers signals from anode pads in 32 transmission lines which are read-out
from both ends. Amplifier boards and SAMPIC modules, developed in our labs,
allow us to realize the cost-effective, multi-channel digitization of signals
with excellent precision. For a single photo-electron, we measured a time
resolution of 70~ps (FWHM) simultaneously with a spatial accuracy of 1.6~mm and
0.9~mm (FWHM) along and across transmission lines correspondingly.
