Some embodiments of this disclosure relates to systems and methods for imaging a patient’s vasculature. For example, near infrared (NIR) light can be used to illuminate a target area and light that is reflected or scattered from the target area can be used for generate an image of the target area. In some embodiments, the system can be configured such that the image shows the presence, absence, or extent of infiltration or extravasation in the target area. The system can be configured to document that presence, absence, or extend of infiltration or extravasation at an infusion site. In some embodiments, an imaging system can be mounted onto a patient so that the imaging system can monitor an infusion site, and the imaging system can be configured to automatically detect the presence of infiltration or extravasation.本發明之一些實施例是有關於用於成像患者之脈管系統之系統及方法。舉例而言，近紅外線(near infrared，NIR)光可用以照射目標區域，且自目標區域反射或散射之光可用於產生目標區域之影像。在一些實施例中，系統可經組態以使得影像展示在目標區域中浸潤或外滲之存在、不存在或程度。系統可經組態以記錄在注入位點處浸潤或外滲之存在、不存在或程度。在一些實施例中，成像系統可安裝於患者身上，使得成像系統可監視注入位點，且成像系統可經組態以自動地偵測浸潤或外滲之存在。
