摘要： Systems and methods are disclosed for determining individual-specific blood flow characteristics. One method includes acquiring, for each of a plurality of individuals, individual-specific anatomic data and blood flow characteristics of at least part of the individual's vascular system; executing a machine learning algorithm on the individual-specific anatomic data and blood flow characteristics for each of the plurality of individuals; relating, based on the executed machine learning algorithm, each individual's individual-specific anatomic data to functional estimates of blood flow characteristics; acquiring, for an individual and individual-specific anatomic data of at least part of the individual's vascular system; and for at least one point in the individual's individual-specific anatomic data, determining a blood flow characteristic of the individual, using relations from the step of relating individual-specific anatomic data to functional estimates of blood flow characteristics.

摘要： Systems and methods are disclosed for estimating patient-specific blood flow characteristics. One method includes acquiring, for each of a plurality of individuals, a geometric model and estimated blood flow characteristics of at least part of the individual's vascular system; executing a machine learning algorithm on the geometric model and estimated blood flow characteristics for each of the plurality of individuals; identifying, using the machine learning algorithm, features predictive of blood flow characteristics corresponding to a plurality of points in the geometric models; acquiring, for a patient, a geometric model of at least part of the patient's vascular system; and using the identified features to produce estimates of the patient's blood flow characteristic for each of a plurality of points in the patient's geometric model.

摘要： An infrared (IR) imaging system is presented. The system includes a cooling chamber associated with a cooler generating a certain temperature condition inside the chamber. The cooling chamber has an optical window, and includes thereinside an IR detection unit including one or more detectors thermally coupled to the cooler and at least two cold shields thermally coupled to the cooler and carrying at least two imaging optical assemblies. The at least two imaging optical assemblies are enclosed by the cold shields in between the detection unit and the optical window and thereby define at least two different optical channels for imaging light from the optical window onto the one or more detectors of the detection unit.

摘要： An infrared (IR) imaging system is presented. The system comprises a cooling chamber associated with a cooler generating a certain temperature condition inside the chamber. The cooling chamber has an optical window, and comprises thereinside an IR detector and a cold shield both thermally coupled to said cooler, and an imaging optical assembly comprising one or more imaging lenses defining a certain fixed focus of the imaging assembly and being enclosed by the cold shield in between the detector and the optical window. The imaging optical assembly and the detector are therefore under the same cooling temperature thereby reducing thermal noise in the detected image.
