摘要： The present disclosure is directed to a system and method that detects and measures a vault of an anterior segment of an eye of a patient. The system and method locate an implanted contact lens (ICL) between a cornea and a natural lens, form a B-scan of the eye based on the received ultrasound pulses, removes background pixels, such as by binarizing and thresholding, from the B-Scan from a grayscale color palette to a black/white color palette, determines, from the resulting B-scan a fiduciary location in the anterior segment of the eye, and forms using the resulting B-scan and fiduciary location, a vault map mapping a distance between an anterior segment surface and a posterior surface of the ICL along a plurality of lines drawn perpendicular to a local surface of the anterior segment surface.

摘要： Systems, processes, and apparatuses are provided for imaging a body part of a patient such as an eye of the patient. In some embodiments, a process is provided for adjusting the readings from an ultrasound probe to account for the different speeds of sound through different portions of the eye. In various embodiments, a process is provided for combing multiple images of the body part together. In some embodiments, a process is provided for determining the diameter of the lens of the eye.

摘要： Methods, systems, and devices include locating one or more target structures comprised in an eye of a patient based on processing image data of the eye of the patient, determining one or more measurements associated with an anterior portion of the eye based on the location data, and determining a presence, an absence, a progression, or a stage of a disease of the eye based on the one or more measurements. Locating the one or more target structures may be based on an output provided by a machine learning model.
