  Modified Newtonian Dynamics (MOND) is a gravitational framework designed to
explain the astronomical observations in the Universe without the inclusion of
particle dark matter. Modified Newtonian Dynamics, in its current form, cannot
explain the missing mass in galaxy clusters without the inclusion of some extra
mass, be it in the form of neutrinos or non-luminous baryonic matter. We
investigate whether the MOND framework can be generalized to account for the
missing mass in galaxy clusters by boosting gravity in high gravitational
potential regions. We examine and review Extended MOND (EMOND), which was
designed to increase the MOND scale acceleration in high potential regions,
thereby boosting the gravity in clusters. We seek to investigate galaxy cluster
mass profiles in the context of MOND with the primary aim at explaining the
missing mass problem fully without the need for dark matter. Using the
assumption that the clusters are in hydrostatic equilibrium, we can compute the
dynamical mass of each cluster and compare the result to the predicted mass of
the EMOND formalism. We find that EMOND has some success in fitting some
clusters, but overall has issues when trying to explain the mass deficit fully.
We also investigate an empirical relation to solve the cluster problem, which
is found by analysing the cluster data and is based on the MOND paradigm. We
discuss the limitations in the text.
