Radiographic projections are essential for accurate diagnosis and clinical interpretation. Each projection provides a unique view of anatomical structures and is selected based on the clinical indication. Study the provided radiograph and answer the following questions: Radiograph 1. Identify the radiographic projection used. (1 mark) 1.1 [BLANK-1] 2. Justify your answer by referring to key anatomical features and positioning cues visible in the image. (2 marks) 2.2 [BLANK-2] [BLANK-3]

What is meant by the term ‘pleural effusion’?

40. You are required to perform thoracic spine radiographic imaging. Explain four (4) methods used to improve image quality across the thoracic region. 

# Q8. Which call correctly creates a modern, reproducible NumPy Generator seeded with 404?#     A) rng = np.random.RandomState(404)#     B) rng = np.random.seed(404)#     C) rng = np.random.default_rng(404)#     D) rng = np.random.Generator(404)
