An apparatus includes a transformation table acquiring unit, a blood-flow information acquisition unit and a blood-flow image generating unit. The transformation table acquiring unit obtains a transformation table for transforming unspecified information representing a concentration of a contrast medium in a myocardium into an unspecified blood flow value image based on a CT image acquired in a concentration transition period. The blood-flow information acquisition unit obtains information representing the concentration of the contrast medium based on a CT image acquired during a constant concentration period. The blood-flow image generating unit generates a blood flow value image based on the information representing the concentration of the contrast medium according to the transformation table.

An X-ray CT apparatus has an image generating unit and a blood flow information acquiring unit. The image generating unit acquires projection data at rest and at non-rest from a myocardial part of an object into which contrast medium is injected continuously in a state in which each concentration of the contrast medium can be considered to be constant and reconstructs contrast CT image data at the rest and at the non-rest using the acquired projection data. The blood flow information acquiring unit obtains third blood flow information based in first blood flow information derived from the contrast CT image data at the rest and second blood flow information derived from the contrast CT image data at the non-rest.

The picture archiving and communication system (PACS) substantially optimizes a post-scanning command process in accordance with a user-specified priority for further processing a selected set of imaging data that has been collected by medical imaging devices such as a CT scanner and a MRI scanner and stored in distributed storage units on the network. The user-specified priority includes the least response time, the least costs and the least network traffic. The user-specified priority is optionally fixed in some preferred embodiments.

An X-ray CT apparatus 1 comprises a blood-flow information acquisition unit, a correction value calculating unit and a blood-flow image generating unit 24e. The blood-flow information acquisition unit obtains information of a relative blood flow rate in the myocardium of the subject P based on the CT image. The correction value calculating unit obtains a correction value based on the CT image in a concentration transition period defined to be a period from immediately after starting of a continuously injection of a contrast medium into the subject P until the contrast medium injected reaches to the myocardium, increases, and will be in a state where it can be considered that the contrast medium is saturated in a constant value. The blood-flow image generating unit 24e generating a blood flow value image in the myocardium by correcting the information of the relative blood flow rate with the correction value.

摘要:
SPECT data is collected to produce a SPECT image and transmission CT projection data is collected to produce a transmission CT image. The contours of the body of a subject under examination is extracted from the SPECT image. Using data representing the contours of the body, a portion of the transmission CT projection data is approximated by a curve. The sum of the curve-approximated transmission CT projection data and the center of gravity of the transmission CT image are computed. The truncated portion is estimated from the sum of the transmission CT projection data and the center of gravity of the transmission CT image and the transmission CT projection data is then corrected. The correction of the transmission CT projection data involves producing (extrapolation) anew a curve represented by a quadratic polynomial for that region (truncated region) of the transmission CT projection data which has been approximated tentatively by an ellipse in order to determine the sum and the center of gravity.
摘要:
A diagnostic apparatus for nuclear medicine capable of performing an operation of counting gamma rays for a TCT simultaneously with an operation of counting gamma rays for an SPECT has a SPECT counter for counting, as the number of photons, gamma rays passed through a SPECT energy window centered at a photoelectric peak of the SPECT gamma rays and a TCT counter for counting, as the number of photons, gamma rays passed through a TCT energy window centered at a photoelectric peak of the TCT gamma rays. The number of photons of the gamma rays passed through the SPECT energy window contains the number of photons of K-X rays generated due to a photoelectric effect produced by the TCT gamma rays in collimators of the detector. A K-X ray processor estimates the number of photons of mixed K-X rays on the basis of the number of photons counted at the TCT counter. The K-X ray correction processor performs K-X ray correction on the photon number counted at the SPECT counter on the basis of the photon number of the estimated K-X rays. Since the number of photons passed through the TCT energy window and number of photons of K-X rays passed through the SPECT energy window have a very strong correlation from the standpoint of probability statistics, the accuracy with which the number of photons of the K-X rays passed through the SPECT energy window is estimated is very high. It is, therefore, possible to effectively reduce the K-X rays passed through the SPECT energy window.
