The disclosed embodiments relate to a system that implements a side-viewing imaging catheter. This system includes a catheter sheath enclosing an imaging core, wherein the imaging core resents an internal optical channel coupled to an optical element located at the distal end of the imaging core. The optical element includes an internal reflective surface that reflects and focuses light transmitted via the optical channel in a direction orthogonal to a rotational axis of the catheter toward a target location, and returns reflected light from the target location back through the optical channel. This internal reflective surface of the optical element is shaped to focus the light so that a resulting beam shape at the target location has a small cross section area and substantially equal axial and transaxial dimensions.

A subject is avascularized while changing the avascularization pressure between the avascularized condition and the non-avascularized condition. A receiving circuit receives a detection signal obtained by detecting a photoacoustic wave generated in the subject by emission of measurement light to the subject. Photoacoustic image generation means generates a photoacoustic image based on the detection signal of the photoacoustic wave. Motion detection means detects the motion of each of a plurality of control points set in each photoacoustic image based on photoacoustic images at a plurality of times. Region of interest setting means sets a region of interest based on the motion detected at each control point. Blood flow information generation means generates blood flow information based on the signal strength of the photoacoustic image in the region of interest.

The present disclosure provides methods for path planning, and methods, devices, and systems for determining operation guidance information. The methods include obtaining an X-ray image of a target object, and marking a location of a lesion on the X-ray image of the target object; obtaining an ultrasonic image of the target object, and obtaining a fused image by fusing the ultrasonic image of the target object with the marked X-ray image; and obtaining a planned path by performing a path planning based on a location of the lesion in the fused image. According to the methods provided herein, the problem that a single medical image providing relatively little information and without effective reference for surgery can now be solved. The surgical instrument can be implanted based on the planned path, thereby improving the success rate of surgery and reducing surgical complications.

A device comprises a cannula having a first end, a second end, and a channel between the first end and the second end; an imaging probe couplable to the first end of the cannula, where the imaging probe includes: a transducer, and a reflective surface; and a biopsy device coupled to the cannula, where the biopsy device is configured to collect a tissue sample from an organ of a patient.

This invention relates generally to the detection of objects, such as stents, within intraluminal images using principal component analysis and/or regional covariance descriptors. In certain aspects, a training set of pre-defined intraluminal images known to contain an object is generated. The principal components of the training set can be calculated in order to form an object space. An unknown input intraluminal image can be obtained and projected onto the object space. From the projection, the object can be detected within the input intraluminal image. In another embodiment, a covariance matrix is formed for each pre-defined intraluminal image known to contain an object. An unknown input intraluminal image is obtained and a covariance matrix is computed for the input intraluminal image. The covariances of the input image and each image of the training set are compared in order to detect the presence of the object within the input intraluminal image.

An interventional hysteroscope includes a shaft, an optical imaging element, an ultrasonic imaging element and a treatment element, such as an ablation needle. The shaft has a distal end, a proximal end, and a longitudinal axis therebetween, and the optical imaging element is disposed at the distal end of the shaft. The ultrasonic imaging element is also disposed at the distal end of the shaft and is configured to image along a laterally oriented image path. The treatment element is configured to be deployed from the shaft along a laterally oriented treatment path, and the imaging path and the treatment path intersect at an intersectional location spaced laterally away from the shaft. A display is configured to present both an optical image from the optical imaging element and an ultrasonic image from the ultrasonic imaging element and to present a marker on the ultrasonic image at a location corresponding to the intersectional location.
