Dicom Director

Dicom Director DICOM Director provides secure and rapid transfer of images between clinicians within and between institutions; and creates 3D holographic AR/VR images.

For about a decade, SphereGen has been working in the healthcare data integration space. One of the main problems we discovered was in the area of radiology images and transferring them. We created Dicom Director as a solution to some of the challenges radiologists were bringing to our attention.

Case of the Week from DICOM Director

Right Ventricular Assist Device
A right ventricular assist device does just what it claims, assisting the right heart in pumping blood from the venous system into the lungs.
In this video, we first see the external view with right and left chest tubes seen in blue, cardiac pacing wires in purple and the RVAD itself entering the patient’s left chest wall in green.
With the skin removed, we see more clearly the sternal closure wires in light blue, the right chest tube, placed laterally and coursing superiorly and posteriorly in the pleural space and the left tube placed anterolaterally, running posteriorly and inferiorly. If we enter the right chest directly, we are able to see the both chest tubes in their full orientation within the pleural spaces.
Isolating all the foreign bodies with our Cutting Plane, we are able to clearly see the sternal wires, both thoracostomy tubes, a nasogastric tube running posteriorly, two cardiac pacing wires anteriorly in purple and the three components of the RVAD in green.
Finally, we focus on just the RVAD itself, with pump input catheters in the superior and inferior vena cavae and the pump output catheter, punctured directly into the pulmonary artery. Note the shape of the collapsed balloon on the SVC and PA catheters, indicating that the image was taken during diastole.

Case of the Week:

Stabilization of C1-C2 subluxation with preservation of vertebral artery flow.
A dangerous shift in the uppermost cervical vertebrae was threatening the blood flow to the patient's brain. Dr. Julio Sampaio used INTRAVISION XR from DICOM Director to plan and navigate this delicate procedure and preserve cerebral blood flow.

Case of the week:

A dramatic case of a crush injury to the chest…the transverse ‘lines’ seen are not artifact, but actual tissue imprint from the impact.
In the first segment, we see the shattered sternum, with the cortical bone in white and the medullary bone fragments in blue.
We then see the massive subcutaneous emphysema in black and a large posterior hemothorax in dark red.

The left renal vein normally passes in front of the aorta to reach the left kidney from the inferior vena cava. In some cases, however, there is a vein passing posterior to the aorta, creating a CIRCUMAORTIC LEFT RENAL VEIN.

This occurs in about 3.5% of people, but estimates of the true incidence vary widely. It is rarely of any clinical significance…unless you are a surgeon operating in the area and are not aware that it exists!

Tetralogy of Fallot Part 4

Right ventricular hypertrophy

In normal fetal development, the right and left ventricle pump against similar pressures, resulting in similar myocardial development before birth. In normal development at birth, however, the left ventricle begins pumping against the significantly greater systemic pressure, resulting in rapid hypertrophy of the left ventricle. Normal left myocardium is quickly two to three times the thickness of the right ventricular wall. In Tetralogy of Fallot, however, the right heart pumps against the restricted outflow of the malformed conotruncal outflow tract: right ventricular blood can either go out the overriding aortic valve to the high pressure systemic circulation, or through the stenotic pulmonic valve. This added pressure load on the right ventricle results in hypertrophy of the right ventricular myocardium.

INTRAVISION XR from Dicom Director is defining the era of human digital twins...and what they can do for medicine.

Tetralogy of Fallot Part 3
Ventricular septal defect
Externally, there is no indication of developmental issues with the ventricular septum. As we enter the right ventricle, we again see the trabeculae carnae, and the leaflets of the tricuspid valve with the attached chordae tendinae. As we approach the ‘overriding’ aortic valve, note that we can suddenly enter into the left ventricle through a large defect in the intraventricular septum, just below the aortic valve. Within the left ventricle, we again see the papillary muscles and associated chordae tendinae. Note that what appeared to be the lateral edge of the aortic valve, is in fact the inferior edge of the ventricular septal defect itself; the aortic valve sits almost perfectly astride the intraventricular septum. The developmental defect of the aortic root and the VSD are intimately related.

As promised, Tetralogy of Fallot as you have never seen it before.

Part 2: Over-riding Aorta
As noted last time, the root cause of the syndrome is conotruncal/outflow tract malformation…it all starts with incomplete development of the outflow tract from both ventricles. Just as we saw atresia of the pulmonary outflow tract, we also see the corresponding ‘over development’ of the aortic root.
From the outside, again note the size of the aorta relative to the pulmonary artery, both expected to carry the same volume of blood with each contraction. As we enter the right ventricle, we see the three leaflets of the open tricuspid valve, and the delicate chordae tendinae connecting them to the papillary muscles.
What we don’t expect to see is the three closed leaflets of the aortic valve, outlined in yellow, from within the right ventricle. The malformation of the conotruncal outflow tract leads to the aorta ‘overriding’ the pulmonary artery into the right ventricle and subsequent inefficient left ventricular outflow.

As promised, Tetralogy of Fallot as you have never seen it before.

Part 1: Pulmonary stenosis/atresia

The root cause of the syndrome is conotruncal/outflow tract malformation…it all starts with incomplete development of the outflow tract from both ventricles.

In this video, we first see the external structure of the heart; notice the size of the pulmonary artery (with the purple band) relative to the aorta. These vessels must carry the same volume of blood with each heartbeat. Moving inside the heart, we see the aortic valve from inside the right ventricle, outlined in yellow, consistent with the overriding aorta (stay tuned for Part 2!) and the two leaflets of the pulmonic valve within the very stenotic pulmonary outflow tract. Note both the aortic and pulmonic valves are closed, consistent with the image being obtained during diastole.

Travelling through the pulmonic valve, we enter the pulmonary artery, make a sharp U-turn and then head back through the pulmonic valve again into the right ventricle. Note the trabeculae carneae of the right ventricular wall as well as the papillary muscles and the chordae tendinae connecting them to the valve leaflets.
