Artificial intelligence (AI) tends to emerge as a relevant component of medical care, previously reserved for medical experts. A key factor for the utilization of AI is the user’s trust in the AI itself, respectively the AIt’s decision process, but AI-models are lacking information about this process, the so-called Black Box, potentially affecting usert’s trust in AI. This analysis’ objective is the description of trust-related research regarding AI-models and the relevance of trust in comparison to other AI-related research topics in healthcare. For this purpose, a bibliometric analysis relying on 12985 article abstracts was conducted to derive a co-occurrence network which can be used to show former and current scientific endeavors in the field of healthcare based AI research and to provide insight into underrepresented research fields. Our results indicate that perceptual factors such as “trust” are still underrepresented in the scientific literature compared to other research fields.
