摘要： Provided is a method of processing image data and detecting a region of an image represented by the image data to be excluded from an analysis of the image. According to the method, image data captured by a medical modality is received. An evaluation of a portion of the image data representing a two-dimensional view of a subject appearing in the image is conducted to locate, in the two-dimensional view, the region to be excluded from the analysis of the image. A feature pertinent to the analysis appearing in a remaining portion of the image, that is outside of the region to be excluded from the analysis located by the evaluation, is detected.

摘要： An angle detection device (30) includes photoemitters (35), photodetectors (36), a scale plate (34) disposed therebetween, and a control section (33) to control them. The control section (33) includes an AFE (43) to convert analog signals (Ia) of the photodetectors (36) to digital signals (Id) and an arithmetic processor (44) to detect a rotating posture of the scale plate (34) based on the digital signals (Id). The control section (33) simultaneously emits lights from the photoemitters (35) and simultaneously receives the lights by the photodetectors (36). The control section (33) then executes the following data processing for each photodetector (36) one by one in sequence: outputting the analog signals representing an entire area of a light-receiving area of one of the photodetectors and outputting the digital signals converted by the AFE to the processor (44).

摘要： Geographic atrophy of the eye can be detected and measured by imaging the eye at a depth greater than the retinal pigment epithelium (RPE) at a plurality of locations of the eye, for example, using optical coherence tomography (OCT); determining a ratio of the intensities of imaging signals of a retinal layer(s) with respect to the intensity of imaging signals of a sub-RPE layer(s) at each location; determining representative values based at least in part on the determined ratios; generating a map of the representative values; and identifying diseased areas from the map. Contours and binary maps may be generated based on the identified diseased areas. The size and shape of the identified areas may be analyzed and monitored over a period of time.
