Present disclosure provides an insert that is at least partially inserted into a subject, the insert includes: a first light guide member that guides light with a first wavelength; a first light emitting portion from which the light guided by the first light guide member is emitted; a second light guide member that is provided so as to be adjacent to the first light guide member and guides light with a second wavelength different from the first wavelength; a second light emitting portion from which the light guided by the second light guide member is emitted; and a light absorption/conversion member.
Abstract:
Peak specification unit 31 specifies, based on a plurality of photoacoustic-images according to detection signals of photoacoustic-waves detected in a plurality of postures, a photoacoustic-image with the strongest detection signal of a detected photoacoustic-wave among the plurality of photoacoustic-images in a peak search mode. Posture determination unit 32 determines whether or not the posture of the probe 11 at the time of detecting photoacoustic-waves of a generation source of the photoacoustic-image matches the posture of the probe 11 at the time of detecting photoacoustic-waves of a generation source of the photoacoustic-image specified by the peak specification unit in a normal mode. Display control unit 27 displays the photoacoustic image on a display screen, and in a case where the posture determination unit 32 determines that the postures match each other, displays a report indicating the postures matching each other on the display screen.
Abstract:
The invention provides a photoacoustic measurement device that can confirm the position of a puncture needle in a photoacoustic image even in the case where the puncture needle is stuck to a deep position from the surface of a subject. Further, the invention provides a puncture needle that is used for the photoacoustic image generating device. The puncture needle 14 is a hollow needle that has an opening formed at a tip thereof. The puncture needle 14 includes a puncture needle body 31 and a light guide 32. The light guide 32 extends in a longitudinal direction of the puncture needle body. The light guide 32 emits light at least in part to the puncture needle body 31 while guiding light emitted from a light source toward the tip of the puncture needle body.
Abstract:
An acoustic wave detection probe includes a light projection section that emits measuring light to be projected onto a subject, an acoustic wave transducer disposed adjacent to the light projection section and capable of detecting an acoustic wave, an acoustic lens provided on a detection side of the acoustic wave transducer, and a housing accommodating the light projection section, the acoustic wave transducer, and the acoustic lens, in which the acoustic lens and a surface portion of the housing adjacent to the acoustic lens are formed to have an optical property in which the average diffuse reflection factor is 85% or more and the average absorption factor is 10% or less in a wavelength range of the measuring light.
Abstract:
A test device includes a specimen having a circular cross section that accommodates a test target, a specimen holding part that holds a plurality of the specimens in a row, light emitting elements in which light is incident on two adjacent specimens among the plurality of specimens, a first light guide path 46 that guides light emitted by the light emitting elements, and a second light guide path that is formed to have a smaller diameter than a diameter of the first light guide path and that guides the light emitted by the light emitting elements from the first light guide path to the specimen.
Abstract:
A management system including at least one processor, wherein the processor is configured to acquire a captured image obtained by imaging an outer surface of each of plural sample containers which contains a sample and in which discrimination information for discriminating a subject from whom the sample is collected is given to the outer surface, and associate a test result related to the sample contained in each of the sample containers with a test order in which information of a discrimination image including the discrimination information is registered in advance for each subject, based on the captured image and the test order.
Abstract:
A management system includes a label imaging unit that images labels of a plurality of sample containers, a label recognition unit that recognizes a subject by using label images, a test order acquisition unit that acquires a test order of the subject, an automatic association unit that automatically associates a test result related to the sample of each sample container with the test order acquired by the test order acquisition unit by using a recognition result of the label recognition unit, and a display unit that displays the test result and the test order in association with each other.
