    Abstract: A medical image processing method performed by a computer, for measuring the spatial location of a point on the surface of a patient's body including: acquiring at least two two-dimensional image datasets, wherein each two-dimensional image dataset represents a two-dimensional image of at least a part of the surface which comprises the point, and wherein the two-dimensional images are taken from different and known viewing directions; determining the pixels in the two-dimensional image datasets which show the point on the surface of the body; and calculating the spatial location of the point from the locations of the determined pixels in the two-dimensional image datasets and the viewing directions of the two-dimensional images; wherein the two-dimensional images are thermographic images.

    Abstract: The present invention relates to an immobilization mask comprising a first layer comprising a low temperature thermoplastic material, the first layer having a first side and a second side; at least one dimensionally stable attachment section connected to the first layer; and at least one deformable molding member connected to the first side or to the second side of the first layer. The present invention also relates to a method of immobilizing a patient's body part, comprising the steps of applying an immobilization mask comprising a first layer having a low temperature thermoplastic material and at least one dimensionally stable attachment section connected to the first layer, wherein at least one deformable molding member is placed between the first layer and the patient's head; and molding the first layer tightly to the patient's head and to the molding member.
