Minimally invasive surgery continues to prioritize patient safety by improving imaging techniques and tumor detection methods. In this work, an all-optical alternative the current image based for in vitro minimally procedures has been explored. The technique uses a highly fluorescent marker surgical needle be tracked inside simulated tissues. A series of markers were explored including inorganic (Perovskite PbS) organic (carbon dots) nanoparticles dye (Rhodamine 6G) identify layers different stiffnesses within tissue. Rhodamine 6G was chosen on its high fluorescence signal track 3D position homogeneous inhomogeneous gelatin tissues successfully. This exploratory study tissue characterization tip tracking using or photoluminescence show potential real-time application robot-assisted insertions during vivo procedures.

Photoacoustic imaging (PAI) is an emerging hybrid technology that combines the advantages of optical and ultrasound imaging. Despite its excellent capabilities, PAI still faces numerous challenges in clinical applications, particularly sparse spatial sampling limited view detection. These limitations often result severe streak artifacts blurring when using standard methods to reconstruct images from incomplete data. In this work, we propose improved convolutional neural network (CNN) architecture, called multi-scale dense UNet (MSD-Net), correct 2D photoacoustic tomography (PAT). MSD-Net exploits information fusion connections improve performance CNN. Experimental validation with both simulated
