A method and apparatus for obtaining an image to determine a three dimensional shape of a stationary or moving object using a bi dimensional coded light pattern having a plurality of distinct identifiable feature types. The coded light pattern is projected on the object such that each of the identifiable feature types appears at most once on predefined sections of distinguishable epipolar lines. An image of the object is captured and the reflected feature types are extracted along with their location on known epipolar lines in the captured image. Displacements of the reflected feature types along their epipolar lines from reference coordinates thereupon determine corresponding three dimensional coordinates in space and thus a 3D mapping or model of the shape of the object at any point in time.

Compositions and methods for dual imaging and for dual chemotherapy and radiotherapy are disclosed. More particularly, the invention concerns compounds comprising the structure X1—Y—X2, wherein Y comprises two or more carbohydrate residues covalently attached to one another, X1 and X2 are diagnostic or therapeutic moieties covalently attached to Y, provided that when Y does not comprise a glucosamine residue, X1 and X2 are diagnostic moieties. The present invention also concerns methods of synthesis of these compounds, application of such compounds for dual imaging and treatment of hyperproliferative disease, and kits for preparing a radiolabeled therapeutic or diagnostic compound.

Disclosed are an intravascular photoacoustic and ultrasonic dual-mode imaging system and an imaging method, wherein the intravascular photoacoustic and ultrasonic dual-mode imaging system comprises a laser (10), an endoscopic probe (50), an ultrasound transmitting and receiving device (60), a data acquisition system (70) and an image reconstruction and display system (80), wherein the laser (10) is used to output a laser beam and send a trigger signal, the ultrasound transmitting and receiving device (60) is used to control the transmission of an ultrasonic wave, according to the trigger signal, while receiving a photoacoustic signal and an ultrasonic signal, the endoscopic probe (50) is used to laterally reflect the laser beam, after it has been focused or collimated, to a lumen sample to generate the photoacoustic signal by excitation while laterally transmitting an ultrasonic wave and receiving the ultrasonic signal reflected by the lumen sample, the data acquisition system (70) is used to collect a lumen sample photoacoustic signal and ultrasonic signal, and the image reconstruction and display system (80) is used to reconstruct the photoacoustic image and ultrasonic image of the lumen sample. The above-mentioned intravascular photoacoustic and ultrasonic dual-mode imaging system and imaging method improve the utilization of light and the penetration depth of a target tissue, increase the depth and the signal to noise ratio of photoacoustic imaging, and have a better imaging quality.

A dual modality probe is disclosed having both a gamma probe sensor and an ultrasound sensor. A dual imaging system is provided having the probe and at least one external gamma imaging detector and a data acquisition computer system for collecting data simultaneously from the gamma probe sensor, the gamma imaging detector, and the ultrasound sensor of the probe. A method for evaluating a target organ of a patient utilizing the probe and imaging system, and performing a biopsy of the organ is disclosed.
