Abstract: The invention relates to a photonic probe apparatus and a method for probing tissue to detect and mark biological tissue with cancerous or precancerous states. The apparatus involves a probe for illuminating tissue and collecting light from an illuminated tissue region through the probe, a unit for analyzing collected light to determine whether a threshold measure of probability of a cancerous or precancerous lesion in the probed tissue region in contact with the probe is exceeded, and an integrated tissue marking facility which can be activated to mark the probed tissue region through the probe when the threshold measure is exceeded. The photonic probe apparatus and the method are especially suitable for probing regions in squamous and columnar epithelia to detect and mark regions with cervical cancer or cervical intraepithelial neoplasia (CIN).
Abstract: In a rigid distal end portion of an ultrasonic endoscope, a side-viewing optical observation portion and a wave transmission/reception face of an ultrasonic probe are provided on respective sides, in the width direction, of a boundary side wall of a pair of side walls constituting a laterally open recess. The wave transmission/reception face is arranged in a range in which at least a part of the wave transmission/reception face overlaps the boundary side wall, while being offset from an elevator in the longitudinal direction of an insertion portion. When the rigid distal end portion is viewed in an observation direction of the optical observation portion, a top portion of the elevator is located on a line connecting a center of the outer shape of the wave transmission/reception face of the ultrasonic probe, and a center, in the width direction, of the distal end connecting portion of a treatment tool conduit.
Abstract: Systems, apparatuses, methods, and non-transitory computer-readable media for assessing signal quality of a signal are described herein, including determining a signal quality assessment (SQA) metric of the signal based on at least one energy function of the signal, determining whether the SQA metric is above a threshold, and in response to determining that the SQA metric is above the threshold, performing additional signal processing of the signal.

Abstract: Vital sign information of a subject is determined using a marker for application to the subject. The marker is configured to change an optical property due to a mechanical manipulation of the marker caused by a physiological process of the subject. The change in the optical property is detected and analyzed to determine vital sign information of the subject.

Abstract: An exemplary device for detecting a heartbeat of a patient can be provided which can include a transmitter which can provide ultrasonic waves, a receiver that can receive Doppler-shifted ultrasonic waves, and a hardware analyzer coupled to the receiver and which can evaluate a particular moment of the heartbeat of the patient based on a time-dependent signal obtained from the receiver. The hardware analyzer device can comprise a spectrum analyzer configured to extract time-varying frequency component(s) from the time-dependent signal provided by the receiver, and a processing module which can evaluate the moment of the heartbeat based on a variation of at least one of the frequency components in time. The processing module can determine a window of interest (WOI) in time from the variation of the frequency component(s) in time, and the moment when the time-dependent signal provided by the receiver assumes a maximum within the WOI as the moment of the heartbeat.

Abstract: A method and system determines a utility of performing a re-planning on a patient during a radiation therapy planning. Quality improvements which may be made possible by re-planning the patient are automatically estimated, independent of clinician bias. This enables the clinician to make an informed decision regarding whether to re-plan the patient in a fast and efficient manner. This achieves more uniformity and predictability in the adaptive re-planning.
Abstract: The invention generally relates to intravascular imaging system and particularly to processing in multimodal systems. The invention provides an imaging system that splits incoming image data into two signals and performs the same processing step on each of the split signals. The system can then send the two signals down two processing pathways. Methods include receiving an analog image signal, transmitting the received signal to a processing system, splitting the signal to produce a first image signal and a second image signal, and performing a processing operation on the first image signal and the second image signal. The first and second signal include substantially the same information as one another.
