DSF Set
Brand: Leeds Test Objects | Category: Nuclear Medicine & Imaging
A set of four test objects supplementary to the SFS set, checking the parameters most relevant to digital subtraction fluoroscopy imaging. After mask images are taken, the image content is changed by manipulating the plates.

|---|---|
| TO J3 | log and linear subtraction, ADC and DAC operation, 10 step linear and 9 step logarithmic transmission wedges |
| Specification | TO J3 also checks operating headroom with a 9 step wedge exceeding the peak reference level |
| TO Q3 | dynamic range of imaging capability, four quadrants of 100%, 33%, 10% and 3.3% relative transmission |
| Specification | TO Q3 quadrants each contain 16 details of 8 mm diameter |

More from Radiology & Radiotherapy QA Phantoms
- Fluoro 4 / Fluoro 4-L
An image quality phantom for digital and conventional fluoroscopy, used at acceptance and then routinely. It carries limiting spatial resolution, low contrast details, a seventeen step copper dynamic range wedge, a kV test area and an unstructured centre marked region.
- DSA 8/54
A constancy test phantom for digital subtraction angiography systems. A moveable PMMA insert carrying aluminium strips simulates blood vessels and is driven during the exposure by an attached pneumatic hand pump.
- FluoroMesh
A routine fluoroscopy resolution phantom scored by counting the number of mesh patterns resolved in the image. Keeping a record of the count over time reveals any trend towards deterioration in imaging performance.
