Organotin patterning compositions have radiation sensitive ligands with acetal functional groups. Precursor compositions are compositions comprising (OR)(OR)RCRSnL, where the R groups are substituted or unsubstituted hydrocarbyl groups and L is a hydrolysable ligand. The precursors can be formed into coating that can be patterned with radiation, in particular EUV radiation. Coatings formed with blended precursors with hydrocarbyl-based ligands with some having acetal groups and others lacking acetal groups can be particularly effective for improving positive tone patterning.

A self-disinfecting system can include a cladding having a flexible body that conforms to a substrate. The system can further include a disinfection means for disinfecting an exterior surface of the cladding. The disinfection means can be selected from a germicidal irradiation means, a photocatalytic disinfection means, or a chemical disinfection means for disinfecting the exterior surface of the cladding. The germicidal irradiation means can employ germicidal radiation from one or more locations within the body or the substrate to disinfect the cladding. The photocatalytic disinfection means can employ excitation radiation to produce reactive oxygen species using a photosensitizer incorporated into one or more polymeric layers of the body or a coating thereover to disinfect the cladding. The chemical disinfection means can employ a chemical disinfectant incorporated into the one-or-more polymeric layers of the body to disinfect the cladding.

An image processing device 20 comprises an image reconstruction unit 21, an image conversion unit 22, a CNN processing unit 23, and an attenuation correction unit 24. The image conversion unit 22 generates converted images in which the pixel value of a partial region has been changed on the basis of tomographic images for respective slice positions of a subject. In the CNN processing unit 23, the converted images for the slice positions generated by the image conversion unit 22 are inputted to a CNN 31, and slice position information of the converted images is inputted to an embedding layer 32. Output data from the embedding layer 32 is added to a feature map of the CNN 31. The CNN processing unit 23 outputs output images from the CNN 31 as attenuation distribution images for the subject. Thus, even when a medicine administered to a subject when acquiring tomographic images of an attenuation correction target is different from a medicine administered to the subject when acquiring tomographic images for CNN learning, a device capable of creating more accurate attenuation distribution images from the tomographic images of the attenuation correction target is realized.

A method for generating a radiation treatment plan for proton FLASH arc therapy (PF AT) includes receiving at least one image of the region of interest of the subject, where the region of interest includes a target and performing arc selection based on the at least one image to determine a set of arcs. Each arc in the set of arcs is associated with at least one beam angle from a predetermined set of beam angles and one or more radiation beams. The method further includes identifying whether each voxel of the image in the region of interest is a normal tissue voxel or a voxel within the target, optimizing a temporal spread of dose delivery within the normal tissue voxels only, and storing the radiation treatment plan including at least the arc selection and the optimized temporal spread of the dose delivery within the normal tissue voxels.
