The invention provides therapeutic methods for inhibiting, ameliorating or alleviating the hyperproliferative cellular activity of diseases of the breast, e.g., breast cancer, which includes administering to a patient in need thereof an active vitamin D analogue and another anticancer agent. Cell differentiation is promoted, induced or enhanced without causing to the patient dose-limiting hypercalcemia and hypercalciuria.

A radiation therapy system optimized for treating extremities such as the breast has unique geometrical features that enable the system to deliver an accurately located prescribed dose to a target volume while eliminating or reducing the collateral dose delivered to the rest of the patient. The patient lies in a prone position on a rotating, shielded table, with the anatomy to be treated protruding through an orifice in the table into the path of a radiation beam. An optional integral imaging system provides accurate target volume localization for each treatment session. Utilizing the effects of gravity on a prone patient maximizes the separation of a target volume within the breast to adjacent critical structures such as the chest wall, heart and lungs, thereby reducing long term complications not associated with the primary disease. A shielded interface surface between the radiation source and the patient reduces patient dose due to scattered or stray radiation. A shielded enclosure for the radiation sources combined with the shielded interface surface eliminates the need for primary shielding in the room and allows the therapy system to be used in a transportable, mobile facility.

A method for visualizing a dose of X-ray radiation applied to a surface of a patient in a defined time period by an X-ray apparatus is proposed. The X-ray apparatus is adjustable to different angular positions. A model of the surface of the patient is provided. The dose of X-ray radiation applied to the surface of the patient in the defined time period is calculated. The model and the calculated dose on the model is visualized. The visualization of the model and the calculated dose on the model is effected in an angular position coupled to the angular position in which the X-ray apparatus is currently disposed.

The present disclosure relates generally to methods for the increased processing of tissue for the generation of cardiac stem cells, wherein the stem cells are suitable for use in cardiac stem cell therapy. In particular, several embodiments relate to the processing of allogeneic donor cardiac tissue for the generation of multiple patient doses of cardiac stem cells.

In an X-ray CT apparatus including an X-ray area detector that has a matrix structure and is represented by a multi-array X-ray detector or a flat-panel X-ray detector, radiographic conditions (protocols) for imaging of each position represented by a z-coordinate are optimized in relation to an X-ray cone beam that spreads in a z direction. A slice thickness of a tomographic image is freely controlled in the z direction using a z filter during a conventional scan or a cine scan. For each tomographic image, a reconstruction function, an image filter, a scan field, a tomographic-image tilt angle, and a position of a tomographic image are freely adjusted or independently designated for scanning of each position in the z direction. Thus, a tomographic image is reconstructed. Moreover, the position of a beam formation X-ray filter in the z direction is shifted in order to optimize a patient dose that depends on the size of the scan field, and X-ray quality.
