Abstract
The most widely used architecture in large area flat panel imagers is the amorphous silicon passive pixel sensor (PPS), which consists of a detector and a readout switch. While the PPS has the advantage of being compact, reading small PPS output signals requires external column charge amplifiers that produce additional noise and reduce the minimum readable sensor input signal. This work compares the SNR, metastability, area, and off-panel complexity of amorphous silicon active pixel sensor (APS) readout circuits based on three and two transistor current mode and current programmed designs that perform on-pixel amplification of noise-vulnerable sensor input signals to minimize the effect of external readout noise sources associated with ¿off-chip¿ charge amplifiers. The APS circuits presented are poised to replace PPS circuits for fast readout, noise-sensitive, large area, digital medical imaging applications such as dual mode radiography/fluoroscopy and mammography tomosynthesis.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
