Methods: A prospective controlled-study, in two ICUs with assignment to two groups: "US-group" with systematic ultrasound examination of the optic nerve, thorax, heart, abdomen, venous system, performed at the bedside by trained Intensivist.
Brains, hearts, thoraxes, hands – these are called "pro-sections", and it takes a skilled hand to prepare them.

Prior to the electrophysiology study, a maximum of 224 unipolar body surface mapping electrodes compatible with MRI or CТ imaging were placed onto the patient's torso, followed by same-day ECG-gated contrast MRI (Magnetom Avanto, 1.5 T, Siemens AG) or CT (Somatom Definition 128, Siemens AG) scanning of the heart and thorax.

In this study, segmentation of PAT was achieved by isolating the PAT and heart from the thorax using specific anatomic landmarks.
The "gauge point" (GP) on the skin was defined as the position of the mitral valve projected on the skin, estimated on the basis of the contour of the heart on the thorax.
Furthermore, additional patient dose at the kV-CBCT imaging could be less than that at the MV-CBCT imaging, because the mean dose of the simulated tumor in the lung screening phantom was 5.8 cGy at the MV-CBCT imaging used in this study, which was larger than D50 of 0.2 to 0.42 cGy to the heart for representative thorax images at the kV-CBCT imaging reported by Ding and Munro [ 28].
The severity of truncation is influenced by thorax size, heart size, and the axial heart position on the projection.

On postoperative day 1, chest X-ray findings revealed protrusion of the heart into the right thorax (Fig. 3a) and a re-thoracotomy was performed, during which we found cardiac herniation from the repaired pericardial defects (Fig. 3b).
