Hello organizers, I would like to clarify the runtime requirement for Task 3. According to the FAQ, the total runtime for each task should not exceed 1 hour. For Task 3, we understood that there are 300 cases and up to 4 target field-strength generations per input image (excluding the source field strength), which would result in approximately 1200 inference runs. Given the image size (364 × 436 × 364), this seems to imply only a few seconds per volume including I/O and preprocessing/postprocessing, which feels extremely challenging for full-volume 3D models. Could you clarify the expected runtime requirement per case/volume, and whether the test phase will use cropped regions (similar to validation) or full-volume scans? Also, does the runtime budget include file I/O and preprocessing/postprocessing? We want to make sure we correctly understand the intended evaluation setting. Thank you.

Dear Changseon, Thank you for your questions. For each case, the required submission is the central axial slab only: z in [150, 180), i.e. the (364, 436, 30) region instead of the full 364-slice volume. The amount of data to generate and submit per case is therefore much smaller than the full 364x436x364 grid. Please feel free to reach out if anything remains unclear. Thanks, Jiahao
