  Quantum imaging with undetected photons (QIUP) has recently emerged as a new
powerful imaging tool. Exploiting the spatial entanglement of photon pairs, it
allows decoupling of the sensing and detection wavelengths, facilitating
imaging in otherwise challenging spectral regions with mature silicon-based
detection technology. All existing implementations of QIUP have so far utilised
the momentum correlations within the biphoton state. Here, for the first time,
we implement and examine theoretically and numerically the complementary
scenario - utilising the tight position correlations formed within photon pair
at birth. This image plane arrangement facilitates high resolution imaging with
comparative experimental ease, and we experimentally show resolutions below 10
$\mu$m at a sensing wavelength of 3.7 $\mu$m. Moreover, imaging a slice of
mouse heart tissue at the mid-IR to reveal morphological features on the
cellular level, we further demonstrate the viability of the technique for the
life sciences. These results offer new perspectives on the capabilities of QIUP
for label-free wide-field microscopy, enabling new real-world applications in
biomedical as well as industrial imaging at inaccessible wavelengths.
