In some aspects, the method includes analyzing fMRI data to identify signals related to blood flow, and selecting a zero time lag seed regressor using the identified signals. The method also includes correlating the selected seed regressor to identify a subset of the fMRI data that correlates with the seed regressor and is offset in time, combining the subset of the data to determine a time-delayed regressor, and performing repetitions to obtain a number of time-delayed regressors, where for each repetition, the seed regressor is adjusted using a previous time-delayed regressor. The method further includes analyzing the data using the time-delayed regressors to determine blood delivery from vessels across the brain, and generating a report. In some aspects, a second recursive procedure may be performed using an optimized seed regressor obtained from a first recursive procedure.

Abstract: A tomographic image forming apparatus is disclosed, which divides light output from a light source inside the apparatus into measurement light and reference light, and which generates a cross-sectional image of an imaging target, based on light intensity of interference light obtained from reflected light obtained by emitting the measurement light to the imaging target and the reference light. A second image is generated by converting a first image in which line data generated based on the light intensity and having information in a direction of a first axis which serves as a depth direction of the imaging target is arranged in a direction of a second axis, into a frequency domain. An artifact is removed or reduced by performing filtering on the second image. A third image is generated by inversely converting the processed second image into a spatial domain.

Abstract: Determining the progression of reflux disease in the esophagus of a patient includes identifying the location of an endoscopic gastroesophageal junction in the esophagus, removing a length of tissue of the esophagus that includes a portion of the endoscopic gastroesophageal junction, and identifying the proximal limit of tissue containing cardiac epithelium. Determining the length of the squamo-oxyntic gap of the biopsied tissue can involve measuring the length of tissue extending between the proximal limit of tissue containing gastric oxyntic epithelium to the proximal limit of tissue containing cardiac epithelium. A linear relationship can be determined from a slope of a line extending between a first data point and a second data point that can determine a target age of the patient when the lower esophageal sphincter will have a certain length.

Abstract: Methods and system perform tool tracking during minimally invasive robotic surgery. Tool states are determined using triangulation techniques or a Bayesian filter from either or both non-endoscopically derived and endoscopically derived tool state information, or from either or both non-visually derived and visually derived tool state information.

The endoscopically derived tool state information is derived from image data provided by an endoscope inserted in the body so as to view the tool.
