An image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry recognizes at least one of chest wall, vessels, nodules, and tumors by increasing sensitivity to a gradient and a sensitivity to a cavity structure in three-dimensional data including a lung area. The processing circuitry generates a data removing process for removing data derived from the chest wall and a data holding process for holding data derived from at least one of the vessels, the nodules, and the tumors on a basis of a result obtained by the recognizing. The processing circuitry outputs the lung image data. 1. An image processing apparatus comprising processing circuitry con figured to:recognize at least one of chest wall, vessels, nodules, and tumors by increasing sensitivity to a gradient and a sensitivity to a cavity structure in three-dimensional data including a lung area,generate lung image data corresponding to the lung area by performing a data removing process for removing data derived from the chest wall and a data holding process for holding data derived from at least one of the vessels, the nodules, and the tumors on a basis of a result obtained by the recognizing, andoutput the lung image data2. The image processing apparatus according to claim 1 , wherein the processing circuitry generates pre-processed lung image data which is obtained by extracting the lung area from the three-dimensional image data through pre-processing different from the data removing process and the data holding process claim 1 , and performs the data removing process and the data holding process on the pre-processed lung image data claim 1 , thereby generating the lung image data.3. The image processing apparatus according to claim 1 , wherein the processing circuitry recognizes the data derived from the chest wall by using claim 1 , as the sensitivity to the gradient claim 1 , a function including the grey value as an exponent.4. The image processing ...
