Abstract: A Bowman's Refractive Index (BRI) for quantification of microdistortions in Bowman's Layer (BL) after Small Incision Lenticule Extraction (SMILE) is defined for a patient. BRI is summation of one or more areas of the OCT image of anterior edge of Bowman's layer, quantifies the smoothness of the Bowman's layer. The anterior edge of Bowman's layer is segmented into pixels. After segmentation, a 3rd order polynomial is curve fit to the segmented pixels of the edge of Bowman's layer. BRI is calculated by segmentation of the 3-Dimensional (3-D) OCT image. BRI acts as a marker for mechanical stability and is useful for diagnosis of disease and prognosis of treatments in human.

Abstract: A handheld, multipurpose medical diagnostic instrument capable of examining a patient's ears and eyes, detecting the patient's body temperature, capturing the patient's photograph for a patient profile and capturing the target of interest, and transmitting the collected data to an external device. The obtained images, video, and/or data may be displayed on at least one display screen for viewing in real time or for later viewing.

Abstract: An ultrasound diagnostic apparatus includes: a collation pattern memory that stores a plurality of collation patterns corresponding to a plurality of examination parts of a subject in advance; an information input unit that is used by a user to input examination type information; a determination order decision unit that decides a determination order of the plurality of examination parts to be continuously examined, on the basis of the examination type information input to the information input unit; and a part determination unit that reads the collation patterns corresponding to the examination parts to be continuously examined from the collation pattern memory according to the determination order decided by the determination order decision unit and sequentially collates the ultrasound image in the determination order using the read collation patterns to determine an imaging part of the subject.

Abstract: A method for computing fractional flow reserve (FFR), including receiving geometrical parameters of a blood vessel segment including a proximal end and a distal end, the geometrical parameters including a first geometrical parameter, a second geometrical parameter and a third geometrical parameter; and with the proximal end as a reference point, deriving a reference lumen diameter function and a geometrical parameter difference function based on the geometrical parameters and the distance from the position along the segment of blood vessel to the reference point. Derivatives of the geometrical parameter difference function are calculated in multiple scales. FFR is computed as a ratio of a second blood flow pressure at the first location of the blood vessel to a first blood flow pressure at the proximal end of the segment based on the multiple scales of derivative difference functions and the maximum mean blood flow velocity.

Abstract: Provided herein is a phantom capable of mimicking both a dense breast and a fatty breast. A phantom for ultrasound measurement includes: a first member that mimics an object of interest for measurement; and a second member having provided therein the first member. The second member has the property to decrease its sound speed with a temperature increase brought by external temperature control. The sound speed of the second member at a predetermined temperature is equal to the sound speed of a third member surrounding the second member. The first member and the second member are immiscible with each other.

Abstract: A capsule for measuring motility of a target area is provided. An article of manufacture for measuring motility of a target area, comprises a first capsule and a second capsule. The first capsule comprises a first capsule enclosure; a first identification marker, having a weight of Wm1, wherein the first identification marker comprises a first visible element under X-ray, substantially circular shaped and having an outer diameter of A. The second capsule comprises a second capsule enclosure; a second identification marker, having a weight of Wm2, wherein the second identification marker comprises a second visible element under X-ray, substantially circular shaped and having an outer diameter of B. The first capsule enclosure and second capsule enclosure are substantially identical under all measurements in digestive behaviors; the weight of the first identification marker Wm1 and the weight of the second identification marker Wm2 differs less than 0.01 g; A is less than B.

Abstract: A physiological signal measurement device includes a housing, a bracket, a rigid circuit board fastened in the housing, a first flexible circuit board assembled in the housing and the in-ear portion, and a protective sleeve. The housing protrudes frontward to form an in-ear portion. The bracket has a base portion fastened to the in-ear portion. Several portions of a front surface of the base portion protrude frontward to form a plurality of first elastic portions. The first flexible circuit board has a resilient end. The resilient end of the first flexible circuit board surrounds the plurality of the first elastic portions. The protective sleeve has a fastening portion, and a plurality of spaced second elastic portions protruded from the fastening portion. The plurality of the spaced second elastic portions surround the plurality of the first elastic portions and the resilient end of the first flexible circuit board.
