Multi-volume rendering of single mode data in medical diagnostic imaging
Separate renderings are performed for data of a same medical imaging mode. The data is processed differently prior to rendering and/or rendered differently to enhance desired image information. For example, a same set of ultrasound B-mode data is rendered with opacity rendering and with maximum intensity projection or surface rendering. The surface or maximum intensity projection highlights strong transitions associated with bones. The opacity rendering maintains tissue information. Different sets of B-mode data may be separately rendered, such as one set processed to emphasize contrast agent response and another set processed to emphasize tissue. The separate renderings are aligned and combined. The combined rendering is output as an image.
