The present invention provides a triple fusion imaging device for sentinel lymphadenectomy for laparoscopic surgery including: a composite laparoscope for near infrared ray/gamma ray/visible ray acquisition configured to acquire triple images of a gamma ray from a gamma ray radioactive material injected to a diseased part, a visible ray, and a near infrared ray; an optical fiber configured to transmit the triple images acquired from the composite laparoscope; an optical source configured to generate a white light for acquiring a visible image through the optical fiber and a near infrared ray excitation light for acquiring a near infrared ray image by exciting a near infrared ray emitting fluorescence material at the disease part; an optical-to-electrical conversion module configured to separate individual images of the visible ray, near infrared ray and gamma ray from the triple images delivered through the optical fiber and then respectively convert the individual images to electrical signals; a matching unit configured to match a visible image signal, a near infrared image signal and a gamma ray image signal from the optical-to-electrical conversion module to one image; and an image display unit configured to display the image from the matching unit.

Provided are apparatuses and methods of resampling event data for quantitative improvement of a PET image, which acquire a quantitatively-improved new PET image by analyzing a storage format of list data prior to conversion into the PET image and nonparametrically resampling event data from the list data based on the analysis results to improve noise and statistical characteristics thereof. The quantitatively improved new PET image may be acquired by analyzing a storage format of list data constituting the PET image and nonparametrically resampling event data to improve noise and statistical characteristics thereof.

An apparatus and method for determining an optimal energy window for optimal positron emission tomography (PET) is disclosed. An optimal energy window determining apparatus may include a data corrector configured to correct data measured from an image quality phantom, an image quality measurer configured to measure an image quality for the corrected data, and an optimal energy window determiner configured to determine the optimal energy window based on the measured image quality. The data corrector may correct the measured data based on a difference between sensitivities measured using different radiopharmaceuticals in at least one energy window.
