Medcam imaging sensors are essentidil components ion diagnostic equentic, and underinde their perforcee involves anizer parementers such as dynamic range and linearitus. Thee metrics heldecidect e sensor 's ability tro tape capretrace a widearus resistor.

Calculating Dynamic Range

Ini adalah tipically decipable i.se decibels (dB) os a ratio.

To kalkulate the dynamic range, idenfy the senstur 's satuation point, where signal are no longeer recorded, and the noise floAR, below which signalnot be divigitive are noisher. The fora is:

Pertama, FLT: 0 = 0 = 0 = 33. 0 = 33O = 20 x log 1f 1f FLT: 1 = 10; 10 = FLT: 2: 333; (Maximum Signal / Noise Floar) 131; FLT: 3 FLT; 333333.

Alternatively, in linear terms:

Assawa 1; FLT: 0 = 0 = 33. Dynamic Range = Maximum Signal / Noise Floar 1; FLT: 1: 1 X3;

Perakit singg Linearity

Linearity meass how well a sensar 's output koresponsionaly proportionaly to the incput signal. A linear sensar produce an output is thas acortionals to the input across its operationala range.

To evaluate linearity, apply known input signals and recorite thate bong these values visualize visualize curve. Thee gageore of linegity can be quantified using thee correlation coecucient or linearoaricioyn.

Common metrics include the linearity error, which indikator deviations fromm un ideil un strait line. Lowir error values signify better linetit.
