Medical image diagnosis apparatus and image data processing apparatus

摘要

A medical image diagnosis apparatus and an image data processing apparatus that diagnoses vascular invasion status of a tumor and decides the most appropriate therapy method for the tumor by extracting tumor candidate regions and vascular regions based on extensive volume data derived from covering a therapy target organ, and specifying an adjacent vascular region existing within a prescribed scope from a gravity center of a tumor. The tumor candidate regions and vascular regions are generated as 3D image data or MPR image data for submitting a recommended therapy method for the tumor by adding branch data of the adjacent vascular.

1. A medical image diagnosis apparatus comprising;
a volume data generator including an image data memory configured to store image data sequentially acquired from a therapy target organ through an image acquisition device, a high speed arithmetic processor configured to generate 3D data based on the image data read out from the image data memory and an interpolation processor configured to generate volume data in time series based on the 3D data; a vascular region detector implemented by circuitry configured to detect vascular regions in the therapy target organ using volume data of vascular enhanced phases selected by processing circuitry from among the volume data generated in time series, the vascular enhanced phases corresponding to timings of brightness changes; a tumor candidate region detector implemented by circuitry configured to detect tumor candidate regions in the therapy target organ using volume data of tumor enhanced phases selected by the processing circuitry from among the volume data generated in time series, the tumor enhanced phases corresponding to timings of brightness changes; tumor position data measuring circuitry configured to detect each gravity center of the tumor candidate regions; an adjacent vascular detector implemented by circuitry configured to
obtain first information of the vascular regions detected by the vascular region detector and second information of the tumor candidate regions detected by the tumor candidate region detector, anddetect, using the first and second information, the vascular regions adjacent to the tumor candidate regions that exist within a prescribed range from each gravity center of the tumors as adjacent vascular regions; and an image data generator implemented by circuitry configured to generate therapy assisting image data based on narrow scope volume data including the tumor candidate regions and the adjacent vascular regions extracted from the volume data.
