Abstract: A system and method for displaying MRI parameters measured from a tissue sample such a tumor. A computer system receives MRI data and determines a number of parameters including, a normalized cerebral blood volume (nCBV), a contrast transfer rate constant (kTrans) and apparent diffusion coefficient (ADC) calculated from Bo and B1000 MRI images for data points in the MRI data. These parameters are plotted onto a three-dimensional graph of voxels where the data in the MRI are mapped to a normalized radial distance and angle in the plot. The parameters nCBV, kTrans and 1/ADC are mapped to a color of the voxel and to height of a voxel in the +Z and ?Z axes of the three dimensional plot.

Abstract: A lamp retaining device for holding a lamp within a housing. The lamp retaining device includes a bracket adapted to mount to a housing. The bracket includes a channel formed therein which has a portion oriented such that an end of the lamp will rest unaided thereon. To positively secure the lamp into the bracket, a retainer is coupled to the bracket. More specifically, the retainer includes a retaining portion which is configured for insertion into the channel to positively secure the end of the lamp into the oriented portion of the channel. The retainer further includes a coupler to allow selective coupling and uncoupling of the retainer and the bracket.

Abstract: A lamp assembly comprising an elongate source of radiation, a reflector with an elongate reflective surface partly surrounding the source and having an opening for emission of radiation down towards a substrate for curing a coating thereon. The reflective surface has a generally concave profile and the source is located near the base of the concavity. The reflector includes two reflector elements each having a shaped surface which combines with the other when the elements are held in a first relative position to form a cavity in which the source is located and on the surface of which the reflective surface is provided. The source is mounted to be movable with one element to a second position relative the other element in which the source is located in a user accessible position.

Abstract: A lamp assembly has an elongate source of radiation and an elongate reflective surface partly surrounding the source for reflecting radiation from the source onto a substrate for curing a coating on the substrate. The reflective surface has a profile which is substantially continuously concave curved and is shaped with respect to the source such that less than 10% of the radiation emitted from the source is reflected back onto the source.
